In this paper, a heuristic adaptive routing algorithm for an energy-efficient configuration management has been suggested which can reduce energy consumption while guaranteeing QoS for the emergency data in wireless body area networks (WBANs). The priority and vicinity of the nodes are taken into account for the selection of reachable parent nodes, when the nodes are disconnected due to the mobile...
In this paper, we provide a comprehensive survey of recent energy-efficient medium access control (MAC) protocols for wireless body area networks (WBANs) and presents a comparison of the various approaches pursued. At the outset, we outline the crucial attributes for a good MAC. Several sources that contribute to the energy inefficiency are identified. Then, we investigate few MAC protocols devised...
Providing handover with guaranteed QoS for realtime multimedia service such as VoIP, video/audio streaming, and video conferencing in wireless LAN is a challenging task. In this paper, we present a context-aware mobility management mechanism in wireless LAN, which can provide fast handover with guaranteed QoS for real-time multimedia service. To this end, the scanning period and the number of channels...
