Research team aims to enhance security of medical devices
Tamer Nadeem, Ph.D., the principal investigator of the VCU-based MedKnights project, explained that the project’s focus is on the Internet of Medical Things (IoMT). Nadeem and co-PI Irfan Ahmed, Ph.D., both associate professors in the VCU College of Engineering Department of Computer Science, recently received $600,000 from the NSF’s Office of Advanced Cyberinfrastructure to put together a framework to improve IoMT security.
IoMT devices are used in a range of diagnostic, monitoring and therapeutic applications. IoMT includes patient monitors, ventilators, MRI machines — even “smart beds.” Ahmed cited the internet-connected insulin pump is a good example of an IoMT device. Internet connectivity allows for both monitoring and adjusting the dosage remotely — functions that require a high degree of security for patient privacy as well as safety.
All IoMT devices are potentially vulnerable to ransomware, denial of service and other malicious hacker attacks. Nadeem points out that IoMT devices have a higher security requirement than traditional IoT devices such as smart doorbells and smart thermostats in homes.
“The most important thing in the medical domain is privacy,” Nadeem said. “For IoT devices in your home, you wouldn’t care that much about privacy, but for medical devices, it is an essential thing. You wouldn’t want anyone to know what your health conditions are, or what problems you might have had.”
The work of the MedKnights group is important, as the IoMT domain is expanding; there is growth in terms of types of devices, number of patients using them and number of IoMT vendors. Nadeem added that the COVID pandemic and accompanying quarantine and stay-home orders increased the focus of medical-technology providers on the possibilities of IoMT.
“Talking to some of the medical-device providers, I’ve learned that they are considering a line of products where they can remotely monitor patients on those devices, and they also can configure those devices remotely,” Nadeem said.
Security is a large concern for the new generation of devices, because the current IoMT devices have been hit hard by hackers, he said. Security is an issue that extends from the individual patient to the institution.
“Statistics show there are a lot of ransom attacks being done on the health sectors during the pandemic,” Nadeem said. “That motivated us.”
The MedKnights team’s preparation for taking on the dragon of malicious IoMT attacks includes building a “test bed,” an isolated hardware/software assembly that Nadeem says will mimic the internet-enabled hospital setting.
“In the hospital environment, there’s set of rooms. Each room has a lot of medical devices; they could be wired, or they could be wireless devices,” he said. “But there is no way that we can do what we want to do in a hospital.”
The test bed will incorporate IoMT datasets based on typical device behavior, traffic and known malicious attacks. Nadeem explained that MedKnights will explore vulnerabilities of various IoMT hardware and software by subjecting the elements of the IoMT test bed to a range of attacks.
“We will try to see in real time how efficient our technologies to monitor or detect these attacks, then try to intervene if we notice any change in the activities on the network,” he said. “Now, if the attacks manage to get into the device, we would like to also to start to see whether we can monitor these devices and observe abnormality or any misbehavior.”
Nadeem said the next step is to isolate the source of fishy activity in the test bed network and begin to reverse-engineer the malware. He explained the group will work on understanding the question by looking for the “hole” that created the vulnerability.
Ahmed said the MedKnights will bring undergraduates into the project through DURI, the Dean’s Undergraduate Research Initiative at the VCU College of Engineering. High school students will have an opportunity to join the team through a similar program known as the Dean’s Early Research Initiative, or DERI. DURI and DERI are just two ways of getting younger scientists and engineers involved in actual research.
“For the last couple of years, I’ve been contacted by local high schools to host a couple of their students during the summer,” Nadeem added. “The students were really excited about it. We came up with some nice ideas about how to extend that work to their classrooms. As we continue this project, we will reach out to the schools, because we would love having a couple of their students involved.”

Generative AI for Robust Communication and Efficient Networking
Generative AI is revolutionizing communication by enabling intelligent, automated content creation across text and multimedia, improving efficiency, accuracy, and personalization. It supports diverse applications, from customer service to real-time translation, while advancing technologies like transformers and reinforcement learning to enhance global knowledge sharing. We introduce LoRaFlow, a generative modeling approach using diffusion transformers and rectified flow to reconstruct LoRa signals from noisy inputs, improving demodulation. Integrated with existing LoRa infrastructure, LoRaFlow enhances signal recovery under low SNR conditions with minimal hardware changes, extending the range and reliability of IoT communications.
Modern computer networks, characterized by their high connectivity and heterogeneity, integrate a wide range of devices and protocols such as IoT, sensors, and robotic systems. While this complexity enables advanced services and adaptability, it also introduces significant security vulnerabilities, particularly in critical environments like the Internet of Battlefield Things (IoBT). To address these challenges, this project explores advanced cyber deception techniques aimed at mitigating reconnaissance-stage cyber threats. Two key contributions include MirageNet, a GAN-based framework for generating synthetic network traffic to enhance security and privacy, and MiragePkt, which synthetically generates network packets by learning from raw data. Additionally, a novel Graph Neural Network (GNN)-based approach for optimizing honeypot placement demonstrates superior performance over traditional methods, achieving 92.34% accuracy and a 139x speedup in inference. Together, these innovations highlight the potential of AI-driven solutions in fortifying modern network defenses.
HomePal: Developing a Smart Speaker-Based System for In-Home Loneliness Assessment for Older Adults
Experiences of loneliness are prevalent among older adults. Loneliness is a painful and pernicious state occurring when there is a perceived discrepancy between one’s optimal levels of social interactions and actual social relationships. Lonely older adults are more likely to experience functional decline, including activities of daily living, mobility, and stair climbing. Loneliness has been associated with negative health outcomes, such as increased morbidity and mortality, dementia risk, and cognitive impairment. With longer life expectancy rates, the number of older adults at risk for loneliness will increase substantially, presenting challenges to the healthcare system. However, studies reported that loneliness is a reversible condition, which could be achieved through appropriate interventions, such as improving physical health and social relationships. Detection measures are imperative to identify both lonely and at-risk individuals early enough to intervene before adverse health outcomes occur. The assessment of loneliness is challenging due to the social stigma of being labeled as lonely, resulting in underestimation. Although multidimensional scales exist that do not explicitly use the word “lonely,” healthcare providers do not routinely assess loneliness using validated instruments, making it challenging to be aware of the extent of loneliness among their older adult patients.
ClassyNet - Class-Aware Early Exit Neural Networks for Edge Devices
Edge-based and IoT devices have experienced phenomenal growth in recent years due to rapidly increasing demand in emerging applications that utilize machine learning models such as Deep Neural Network (DNN). However, one of DNN's main drawbacks lies in the large storage/memory requirement and high computational cost, which become a major challenge in adopting these models to edge devices. This led to the development of early-exit models such as BranchyNet that allow for the decision to be made on earlier stages by attaching dedicated exits to the inner layers of the architecture. However, existing early-exit models do not have control over what class should exit when. The need for these novel class-aware models can be observed in multiple edge applications where specific important classes need to be detected earlier due to their temporal importance. In this project, we aim to develop and design ClassyNet, the first early-exit architecture capable of returning only selected classes at each exit. This allows for speedups in inference time for sensitive classes by enabling the first layers to be deployed on edge devices, saving significant computational time and edge resources while maintaining high accuracy.
MedKnights - Towards Secure and Flexible Medical IoT (IoMT) Infrastructure using Generative Adversarial Network
With growing healthcare demands, the Internet of Medical Things (IoMT) has grown significantly in recent years and is dominating the healthcare industry. However, these smarter and advanced medical devices are “more” complicated in terms of software and hardware, with several defects and vulnerabilities that have been found and can lead to possible malicious attacks. Healthcare organizations are the new focus of attackers for carrying out IoMT-focused cyberattacks, which are becoming more common. In recent years, ransomware and distributed denial of service (DDoS) attacks are malware-based popular attacks on IoMT devices. Cyberattacks and disruptions in clinical care can have a catastrophic effect on patient safety, which trickles down to the medical staff’s responsiveness. Moreover, because different medical devices have varying vital capabilities, it is critical to enable differentiated network services for these devices with varying critical levels of operation under network dynamics. Hence, it becomes crucial to efficiently detect and identify any malicious network activities to eliminate or minimize the impact of these attacks, as well as to detect and identify network traffics belonging to different medical equipment.
DeepMAC – Towards A Deep Learning-Based Framework for Automated Design of Networking MAC Protocols
Networking protocols, practically, are designed through long-time and hard-work human efforts. However, these designed protocols, typically, are non-optimum with limited flexibility under several network scenarios and conditions. Moreover, due to evolving network technologies as well as increasing demands of modern applications, ”general-purpose” protocol stacks are not always adequate and need to be replaced by application tailored protocols. Therefore, replacing this inefficient human-based protocol designing process by a novel paradigm that enables rapid design of efficient, flexible, and high performance protocols that intelligently adapt to different device characteristics, application requirements, user objectives, and network conditions is highly desired. In this project, DeepMAC, we explore the first basic steps toward our vision of replacing the human driven network communication design by machine using ML techniques. This vision considers an intelligent system that automates the design of on-line adaptive protocols only by interacting with and learning from the environment, without having any prior knowledge. In this envisioned framework, network protocol stack is decomposed into core functionalities (e.g., switching, routing, congestion control, reliable connection, Backoff, etc.) in which the intelligent agent designs an efficient protocol by selecting the optimum set of functionalities in response to device characteristics, application requirements, user objectives, and network conditions.

US7630343B2
2009-12-08
Disclosed is a wireless station having a receiver and a network allocation vector associated with each of a plurality of directional antennas. The receivers concurrently listen for frames from remote stations. When any receiver detects a frame from a remote station, the receiver activates its associated NAV. The station has one or more transmitters that can transmit using the antennas. While transmitting a signal using an antenna, the receivers associated with any non-transmitting antennas continue to listen for signals from remote stations. The station cancels any signals from the transmitting antenna received by the non-transmitting antennas. To perform the cancellation, the station performs a self-calibration procedure. The station can self-calibrate by either silencing neighboring stations or by inserting null tones into a transmitted calibration signal.

HomePal: Developing a Smart Speaker-Based System for In-Home Loneliness Assessment for Older Adults
National Institue of Health/National Institute of Aging
2023-09-01
Project Abstract Experiences of loneliness are prevalent among older adults. Loneliness is a painful and pernicious state occurring when there is a perceived discrepancy between one’s optimal levels of social interactions and actual social relationships. Given that loneliness has been associated with negative health outcomes, detection measures are imperative to identify both lonely and at-risk individuals early enough to intervene before adverse health outcomes occur. However, the assessment of loneliness is challenging due to the stigma of being labeled as lonely and the lack of integration of loneliness assessments into primary care or community-based services. To tackle the problem, we will use smart speakers and passive sensing data to automatically assess older adults’ level of loneliness as correlates of self-report scores on the UCLA Loneliness Scale. Our goal in this project is to develop, deploy, and validate a smart speaker-based system for in-home loneliness assessment that integrates Internet of Things (IoT) devices to gather both speech (acoustic and prosodic features) and behavioral data (e.g., smart speaker use patterns, in-home mobility, sleep) from older adults. We will enroll 70 individuals (age 65+) living alone in the community to collect digital biomarker data continuously for 3 months. The specific aims are to: (1) Develop an innovative remote loneliness assessment system that allows passive and unobtrusive capture of speech and behavioral data in the home setting; (2) Using a train- test approach, develop and evaluate the performance of novel multi-class machine learning (ML) algorithms— semi-supervised type of Generative Adversarial Networks (SGANs) — to estimate older adults’ loneliness scores. The UCLA Loneliness Scale will be completed by participants every two weeks for 3 months to collect ground truth data; and (3) Identify potential implementation barriers to the effective use of the system among older adults (n=30). In particular, we will assess potential privacy and security concerns, social influence, cultural values, and the level of personification of virtual agents that could influence the adoption and use of the system. The novel ML models will allow us to identify not only “already” lonely individuals but also “at-risk” individuals. The proposed research seeks to provide preliminary evidence that digital biomarkers from smart speakers and IoT devices can be used for automatic loneliness assessment in the community.
OAC Core: MedKnights - Towards Secure and Flexible Medical IoT (IoMT) Infrastructure using Generative Adversarial Networks

With growing healthcare demands, the Internet of Medical Things (IoMT) has grown significantly in recent years and is dominating the healthcare industry. However, these smarter and advanced medical devices are very complicated in terms of software and hardware, with defects and vulnerabilities that are found regularly and they are also vulnerable to possible malicious attacks. Healthcare organizations are the new focus of attackers for carrying out IoMT-focused cyberattacks, which are becoming more common. In recent years, ransomware and distributed denial of service (DDoS) attacks are malware-based popular attacks on IoMT devices. Cyberattacks and disruptions in clinical care can have a catastrophic effect on patient safety, which trickles down to the medical staff?s responsiveness. Moreover, because different medical devices have varying vital capabilities, it is critical to enable differentiated network services for these devices with varying critical levels of operation under varying network dynamics. Hence it is crucial to efficiently detect and identify any malicious network activities to eliminate or minimize the impact of these attacks, as well as to detect and identify network traffic belonging to different medical devices.
The MedKnights project will extend knowledge in networking, machine learning, and the digital forensic domains in developing a holistic framework that can be deployed at the network edge components and effectively support different fine-grained security services for IoMT networks and devices. The main objectives of the project include: (1) creating a novel medical device testbed, IoMT network traffic datasets, IoMT device behavior signature datasets, and attack datasets; (2) employing generative adversarial networks (GANs) to identify many of the interesting features for medical networks and devices, to perform multi-class classification, automatic feature extraction, and be robust to noise, support drifts in networks, and support continual learning for new devices for securing IoMT networks and devices; and (3) enabling remote memory forensic capabilities for IoMT devices. The project will also carry out a number of educational activities involving K-12, undergraduate, and graduate students, make strong outreach efforts for recruiting and mentoring students from underrepresented groups, as well as enrich undergraduate and graduate curricula through exposing students to cutting-edge research in networking, security, and machin

NeTS: Small: SMILE -- Towards Smarter Network Edges for Next Generation Networks
National Science Foundation
2017-11-01
As the number of smart devices and their applications continue to grow, transmission of mobile traffic data over wireless links (i.e., Wi-Fi and cellular links) is continuing to increase significantly. To cope with the explosion of smart devices coupled with a growing proliferation of cloud or edge-based applications, best-effort Quality Of Service is no longer a satisfactory solution and a new breed of intelligent networks is required. More specifically, it is now necessary to have greater visibility and control over the traffic generated from the smart devices in order to deliver optimal performance and a high Quality of Experience to a variety of users and applications. Software Defined Networks (SDN) are a way to facilitate wired network evolution by enabling flexible, controllable, and efficient networks. Motivated by the unique difference of wireless (vs. wired), this project aims to develop and evaluate SMILE (SMart and Intelligent wireLess Edge framework) that supports SDN-like structure at network wireless edge that include both wireless access devices (e.g., Wi-Fi Access Points (APs)) and end-devices. Extending SDN paradigm all the way to smart end-devices would realize our objective in making the network, both wired and wireless, open, flexible and programmable to provide truly end-to-end management and control in which users could reap the full benefits of SDN. The proposed research is expected to advance the state of the art of networking and mobile computing.
The proposed project, SMILE, aims to achieve the following main goals: i) Design and development of SMILE framework that supports wireless networks to be open, flexible, and programmable to cope with complexity, dynamic nature, and uncertainty associated with wireless networks, ii) Draw on the developed SMILE framework to design and develop three different network services such as edge-based fine-grained context-aware video adaptation service, and iii) Implement and evaluate the developed smart protocols and services on medium-scale testbed of smartphones and Wi-Fi APs as well as simulation tools. All schemes/protocols, software development, testbed realization, experimental results will be made open available to the research community. This project will also carry out a number of educational activities involving K-12, undergraduate, and graduate students, make strong outreach efforts for recruiting and mentoring under-represented students, and enriching undergraduate and graduate curri
STTR: Drone-Delivered Naloxone for Opioid Overdose Treatment by Bystanders
National Institutes of Health
2020-07-01
One hundred thirty Americans die from an opioid overdose (OD) daily. The key to improving this survival is the timely delivery of the antidote naloxone. Current US Emergency Medical Services (EMS) systems are often unable to deliver the life-saving drug fast enough manner to save the victim’s life. Our uniquely-qualified team (Virginia UAS, LLC commercial drone pilot training instructors; a Virginia Commonwealth University (VCU) faculty physician EMS medical director/jet and commercial drone pilot with extensive experience leading high-impact, multicenter, prehospital NIH clinical trials; and VCU engineers with experience in development and commercialization of drone hardware and software) has developed a novel prototype drone system that is interfaced to Richmond’s 9-1-1 dispatch computer. The system automatically loads a 9-1-1 bystander caller’s GPS phone location into a drone and launches it to the scene of an opioid OD carrying a lightweight, removable, patent-pending, real-time audio/video package (COMMRx) containing naloxone nasal spray. Just five drones in the City of Richmond could ensure delivery of the naloxone package to bystanders in ≤2 min as EMS first responders begin racing to the scene. Trained 9-1-1 pilot dispatchers would direct the bystander to remove COMMRx from the drone, take it to the victim, and administer the naloxone spray long before first responders can physically reach the victim. This Phase I project proposes to: 1) finalize the system customization; 2) train/FAA-certify seven 9-1-1 dispatchers drone pilots; and 3) perform realistic simulation testing of the system to guide design of a Phase II clinical trial to take place in Richmond, Henrico/Chesterfield counties, and Roanoke, VA. This novel system developed and executed by a uniquely qualified team shifts the paradigm of prehospital emergency care delivery by empowering and directing laypersons to initiate time-dependent, life-saving treatment to opioid OD victims long before EMS personnel can physically treat the patient. Our commercial goal is to expand our flight school business to provide similar capability throughout the 5,783 9-1-1 centers nationally.
Bridging the Disciplinary Gaps in Cybersecurity Curricula through General Education, High Impact Practices, and Training for Incoming Freshmen
US National Science Foundation
2017-08-01
Experts agree that cybersecurity is a multifaceted problem that should be addressed through an interdisciplinary framework; however, most of cybersecurity curricula are offered within specific disciplines. Developing interdisciplinary programs can be challenging with issues such as: student isolation, a disconnect between faculty from the disciplinary programs, a lack of coordination in course delivery, gaps in providing student support, and a lack of a basic interdisciplinary foundation among faculty and students alike. To address these challenges, the "Bridging the Disciplinary Gaps in Cybersecurity Curricula through General Education, High Impact Practices, and Training for Incoming Freshman" project will fully integrate student-focused high impact practices into an interdisciplinary cybersecurity major and minor at Old Dominion University. In addition, an interdisciplinary cybersecurity training module for incoming freshmen will be developed and delivered, and another interdisciplinary general education cybersecurity course will be made available through open education resources (OER). Developing an interdisciplinary general education cybersecurity course will provide students the foundation they need to learn about the topic through a multi-faceted lens.
Integrating high impact practices into interdisciplinary curricula is a novel approach that will bolster the quality of cybersecurity academic programs. These will include learning communities, service learning, internships, undergraduate research projects, and e-Portfolios. The learning communities will include freshmen learning communities, sophomore learning communities, and living learning communities. Each learning community will have a peer mentor assigned. A process will be developed so cybersecurity majors can develop an electronic portfolio in their first-year general studies cybersecurity course, providing a framework for usage over the course of their studies. The development of an open education resource (OER) general studies cybersecurity course will provide a framework that other higher education institutions can use to develop similar courses. Integrating high impact practices into the curricula will provide a framework that can be replicated in other institutions. Graduates of these curricula will be able to fill those occupational cybersecurity positions that require an interdisciplinary background in multiple fields, as well as strong communications and critical thinking skills.

EAGER: Bluetooth Open-Source Stack (BOSS) - A Flexible and Extensible Bluetooth Research Platform
National Science Foundation
2014-12-01
Bluetooth technology continues to evolve and expand, taking advantage of the desirable attributes and features it possesses in comparison to other wireless technologies. With the latest update to the Bluetooth specification (version 4.1), Bluetooth devices are expected to become major players in the much-hyped Internet of Things market. A large body of the research community, utilizing this technology, will require modifications to the lower layers of the Bluetooth protocol. Given the lack of an open-source implementation of Bluetooth stack, the community efforts will be limited in validating and verifying their research under realistic scenarios. This ambitious project aims to design, develop, and disseminate a flexible and extensible open-source Bluetooth platform (BOSS) that will enable new research opportunities for the wireless and mobile computing community. The platform will enable development and evaluation of schemes, services, and applications across all layers of the Bluetooth stack, through the creation of a community-maintained, open-access repository. These goals will be accomplished by: 1) developing a complete Bluetooth open-source platform, by implementing lower layers of the protocol stack as firmware on an existing open-source Bluetooth hardware platform, and extending existing open source upper layers of the stack; and 2) creating and maintaining an open-access repository, where the community will play a key role in generating novel open-source modules.
This project will empower the network community with a tool-set facilitating the development and evaluation of new Bluetooth protocols, applications and services. These new protocols and services could be used to contribute to future Bluetooth standards. BOSS project will have an impact on multiple areas in wireless networks and mobile computing research, such as protocol design, security, wireless network coexistence, and multi-interface smart devices, among others. The project will expose students to cutting-edge research in wireless networks, mobile computing, and computer architecture. In addition, the project?s outcome will be utilized in lectures targeting high school students to educate them about Bluetooth technology and its application as an example of wireless technology as well as Internet of Things. Results from this work will be disseminated through presentations at conferences, journal publications, and reports. An open-access repository, which includes all the designed an
CC*IIE Networking Infrastructure: CHARMED – Campus High-Availability Scientific Research Environment and DMZ
National Science Foundation
2015-01-01
The project builds a full featured "scienceDMZ" that leverages the Old Dominion University's investment in operational high availability resources in the existing data centers routing and switching fabric, incorporates an enhanced and scalable High Performance Computing (HPC) model, and facilitates data intensive research while precluding the need for science projects to create their own stand alone environments. This high performance and high availability computing and networking environment accelerates scientific discovery by increasing the rate at which data can be transferred between collaborators, and by facilitating the creation of communities focused on the data. This project represents a significant shift in promoting and facilitating greater scientific research through collaboration by accommodating the needs of data driven discovery in Physics, Oceanography, Computer Science and Engineering, along with researchers from across campus. Three scientific domains are selected as first users to show the impact of the developed enhanced scientific research environment. The developed environment will have a broad impact on scientific discovery by being a common reliable infrastructure for scientists to host collaboration environments in support of their works. It is envisioned that this infrastructure could be more broadly utilized to accommodate further "Big Data" science in social sciences, biomedical research and public health. This project provides opportunities for enriching the undergraduate and graduate curricula and for exposing students to cutting-edge research in different science domains. Moreover, all of the designs, documentation, and developed tools are made available for other institutions.
CMSC 440: Data Communication and Networking - Spring 2025
This course explores computer networking, focusing on the applications and protocols that run on the Internet. We will take a top-down approach to the layered network architecture, studying applications first and then proceeding down the network “stack” towards the physical link. We will look at the operation of applications such as the web, FTP, e-mail, and DNS. At the transport layer, we will study both connectionless UDP and connection-oriented TCP. Since TCP is the protocol that the majority of Internet traffic uses, we will study its operation in-depth, including flow control and congestion control. We will also look at how data is routed through the Internet, regardless of transport protocol. We will also introduce current “hot” topics, such as network security and wireless/mobile network.
