Abstract

This paper presents an energy efficient routing algorithm for heterogeneous Wireless Body Area Sensor Networks (WBASNs). A prototype is defined for employing heterogeneous sensors on human body. Direct communication is used for real-time traffic (critical data) and on-demand data while multi-hop communication is used for normal data delivery in this proposed routing algorithm. One of the prime challenges in WBASNs is sensing of heat generated by implanted sensor nodes. The proposed routing algorithm is thermal-aware which sense the link Hot-spot and routes the data away from these links. Continuous mobility of human body causes disconnection between previous established links. We introduce mobility support and energy-management to overcome the problem of disconnection due to continuous mobility of human body. MATLAB simulations of proposed routing algorithm are performed for lifetime and reliability in comparison with multi-hop communication. The results show that the proposed routing algorithm has less energy consumption and more reliable as compared to multi-hop communication.
