Book Chapter: Operating Secure Mobile Healthcare Services Over Constrained Resource Networks
Emergent Computation
2017-01-01
Constrained resource (lossy) networks are characterized by low-power and low-processing capability devices. Using lossy networks for service provision is a good approach to overcoming the technological constraints that characterize remote and rural areas of developing regions. In this chapter, we propose a framework for provisioning Healthcare-as-a-mobile-service over lossy networks, as a cost-effective approach to healthcare management in remote and rural areas of developing regions.
Personal Mobile Services
Service Oriented Computing and Applications
2014-09-17
Ubiquitous information access through mobile devices has become a typical practice in everyday life. The mobile service paradigm shifts the role of mobile devices from consumers to providers, opening up new opportunities for a multitude of collaborative services and applications ranging from sharing personal information to collaborative participatory sensing. Although many basic principles of the standard Web service approach continue to apply, the inherent constraints of mobile devices and broadband wireless access render the deployment of the standard architecture in mobile environments inefficient. This paper introduced personal services, a user-centric paradigm that enables service-oriented interactions among mobile devices that are controlled via user-specified authorization policies.
Cloud-Assisted Computation Offloading to Support Mobile Services
IEEE Transactions on Cloud Computing
2014-08-22
The widespread use and increasing capabilities of mobiles devices are making them a viable platform for offering mobile services. However, the increasing resource demands of mobile services and the inherent constraints of mobile devices limit the quality and type of functionality that can be offered, preventing mobile devices from exploiting their full potential as reliable service providers. Computation offloading offers mobile devices the opportunity to transfer resource-intensive computations to more resourceful computing infrastructures. We present a framework for cloud-assisted mobile service provisioning to assist mobile devices in delivering reliable services. The framework supports dynamic offloading based on the resource status of mobile systems and current network conditions, while satisfying the user-defined energy constraints. It also enables the mobile provider to delegate the cloud infrastructure to forward the service response directly to the user when no further processing is required by the provider.
DaaS: Cloud-based Mobile Web Service Discovery
Pervasive and Mobile Computing
2014-08-01
The proliferation of smartphones and the recent advancement in ubiquitous wireless access have made mobile Web services more possible than ever before. However, finding relevant Web services that can match requests and fit user context remains a major concern. The challenges facing Web service discovery are further magnified by the stringent constraints of mobile devices and the inherit complexity of wireless heterogeneous networks. Cloud computing, with its flexible design and theoretically unlimited computing resources, is a viable approach to bootstrapping Web service discovery. The cloud can build bridges between mobile devices, as a convenient ubiquitous interface, and a backbone infrastructure with abundant computing resources. This paper introduces “Discovery as a service (Daas)”, a novel cloud-based discovery framework that addresses the core components of mobile Web service discovery.
A Resilient P2P Architecture for Mobile Resource Sharing
The Computer Journal (Oxford)
2014-07-04
Peer-to-peer (P2P) systems present a unique medium for resource sharing among cliques of participants (peers) in a distributed and self-organized manner. With the advent of mobile users and the increasing power of mobile devices, the spectrum of P2P capabilities should scale. Peers establish transient or persistent relationships with other peers based on mutual interest. Communicating peers may use intermediary peers to forward communication messages, if a direct link is beyond their communication range. A critical design parameter is establishing a resilient communication topology, yet reduce the overhead of control messages required to instill and maintain it. This rises as a significant hindrance in mobile environments, which pose additional challenges on P2P networks due to the heterogeneity of nodes, limited resources, dynamic contexts in addition to the inherited wireless network stringencies. Thus far, efforts in establishing P2P networks via super peers (SPs) have been capped by considering a subset of peer properties to evaluate their candidacy. This paper presents RobP2P, a robust architecture to construct mobile P2P networks and efficiently maintain network state.
Mobile Web Services: State of the Art and Challenges
International Journal of Advanced Computer Science and Applications
2014-03-01
For many years mobile devices were commonly recognized as Web consumers. However, the advancements in mobile device manufacturing, coupled with the latest achievements in wireless communication developments are both key enablers for shifting the role of mobile devices from service consumers to service providers. This paradigm shift is a major step towards the realization of pervasive and ubiquitous computing. Mobile Web service provisioning is the art of hosting and offering Web services from mobile devices, which actively contributes towards the direction of Mobile Internet. In this paper, we provide the state of the art of mobile service provisioning as it currently stands. We focus our discussions on its applicability, reliability, and challenges of mobile environments and resource constraints. We study the different provisioning architectures, enabler technologies, publishing and discovery mechanisms, and maintenance of up-to-date service registries. We point out the major open research issues in each provisioning aspect. Performance issues due to the resource constraints of mobile devices are also discussed.
