Data transmission reliability and energy efficiency are most crucial for Wireless Body Area Network (WBAN) to perform healthcare monitoring. In this paper, the authors jointly consider adaptive power control and routing in multi-hop WBANs, and develop a low overhead Energy-Efficient Routing Scheme (EERS). The proposed EERS can establish an energy-efficient end-to-end path as well as adaptively choose transmission power for sensor nodes. They conduct extensive experiments on a MicaZ platform to compare the performance of the proposed EERS and the Collection Tree Protocol (CTP) in terms of Packet Reception Ratio (PRR), collection delay, energy consumption, and energy balancing.
