Energy Hole Analysis for Energy Efficient Routing in BANs

Wireless Body Area sensor Networks (WBANs) enable innovative health care monitoring. Limited energy source of a sensor node limits WBANs for long time monitoring of health care. Efficient energy utilization is therefore one of the research challenges inWBANs. In this research work we analysed energy utilization of popular routing techniques. We formulate a mathematical framework to identify energy utilization in transmission, receive and over-hearing processes. Simulation results show that how distance, packet size, and over-hearing effect different routing techniques from energy consumption perspective. From the analysis, we produced useful results which are helpful in: identifying overloaded nodes in the network which may cause creation of energy holes, and in designing new routing techniques for specific WBANs application.
