The paradigm shift of network design from performance-centric to constraint-centric has called for new signal processing techniques to deal with various aspects of resource-constrained communication and networking. In this paper, we consider the computational constraints of a multimedia communication system and propose a video adaptationmechanism for live video streaming of multiple channels. T...

Data-Centric approaches based on data-aggregation strategies and in-network processing has been shown to be an interesting strategy to improve scalability conditions, optimize information dissemination, minimize redundancy and increase network lifetime in wireless sensor networks (WSN). In critical-mission WSN applications, secure in-processing strategies translates to both efficient, reliable,...

Since the last few years there has been a phenomenal growth in the wireless industry. Widespread wireless technologies, increasing variety of user-friendly and multimedia-enabled terminals and wider availability of open source tools for content generation has lead encouraged user-centric networks resulting in a need for efficient network design. The objective of this paper is comprehensive stud...

Motivation  Mobile Internet and explosion of its applications, users are experiencing abundant services from different content providers via different network service providers in heterogeneous network.  Information centric network (ICN) advocates getting rid of current host-centric network protocol because information dissemination rather than end-to-end communication contributes to majority...

the problem of posture detection is of considerable significance for assisted living (AL). In most cases, radio channel models for WBANs are fixed when a specific body posture is considered. To the best of our knowledge, little work has been done on the reverse body posture information extraction using WBAN radio channel characteristics. This paper aims to classify human postures from on-body n...

We propose a resilient cache replacement approach based on a Value of sensed Information (VoI) policy. To resolve and fetch content when the origin is not available due to isolated in-network nodes (fragmentation) and harsh operational conditions, we exploit a content caching approach. Our approach depends on four functional parameters in sensory Wireless Body Area Networks (WBANs). These four ...

In this paper, on-body propagation modelling has been investigated applying various numerical computational techniques. Propagation measurements with body-worn antennas have been carried out at 2.4GHz inside and outside an anechoic chamber respectively for narrowband communication channel characterisation. Both simulation and measurement results have been also obtained at the UWB (Ultra Wide-Ba...

Rakesh Kumar Yadav, Kusum Gupta, Ajay Singh Yadav Abstract— Due to many constraints of nodes in wireless sensor networks, a variety of data dissemination protocols have been developed for data gathering in wireless sensor networks. Sensors extract useful information from environment; this information has to be routed through several intermediate nodes to reach the destination. Effective informa...

—This paper explores the next generation of mobile communication system from different perspectives. A user-centric approach to 4G is considered. We envision 4G as a convergence platform where wide-area (cellular) technology, wireless metropolitan area network (WMAN) and wireless local area network (WLAN) will coexist and complete. Legacy systems, their evolution as well as newly developed acce...
