A Reliable, Energy Aware and Stable Topology for Biosensors in Health-care Applications

摘要

Advancements in Wireless and Micro-Electro-Mechanical Systems (MEMS) devices empowered a vast variety of wearable wireless sensors to be used for Wireless Body Sensor Networks (WBSNs). With technological changes WBANs are most capable approaches for allowing remote patient monitoring, improving the quality life and other Medicare applications. In this paper a Reliable, Energy Aware and Stable Topology (REAST) is proposed for WBSNs. For deployment of heterogeneous bio-sensors on patient body this topology is employed. We used direct and indirect communication for real-time and normal data delivery respectively. With indirect communication, any node can be elected as forwarder node, which can gather information from bio-sensors and then aggregating it for further transmission to the sink. Temperature and cost function of the bio-sensor node is considered for selection of node as a forwarder. The proposed algorithm to be simulated by considering parameters such as network lifetime, path loss and packet delivery. These parameters of the proposed network are compared with ATTEMT.
