HEAT: Horizontal Moveable Energy-efficient Adaptive Threshold-Based Routing Protocol for Wireless Body Area Networks

Approaches of using Wireless Body Area Sensor Network (WBASN) in health care applications are getting much popularity. WBASN is a hot topic among the research community. Our proposed Horizontal moveable Energy-efficient Adaptive Threshold-based (HEAT) protocol is well suited for horizontally moving (walking) human body. The on body nodes attached at arms and legs of human body move forward and backward to sink during horizontal movement. We use direct communication for emergency data and multi-hop communication strategy for normal data transmission. Simulation results show that our proposed protocol performs better in terms of stability period and network lifetime. The stability period of HEAT is comparative with direct communication, while it outperforms direct communication in term of network lifetime.
