An Efficient and Stable Route Protocol in Wearable Body Networks

Abstract

A wearable body network (WBN) can extract useful information from the human body. Meanwhile, it has little impact on human movement, although the energy is limited to a single wearable sensor. Then, an efficiency route protocol, which can save the energy-consumption available for WBN is important. On the other hand, the body sensors are movable with human movement. Then, a stable dynamic route protocol is more suitable for WBN. In this paper, a stable dynamic forward-connected route protocol (SDFR protocol) for WBN is proposed, which is a completely self-organized, energy-efficient, and dynamic network. In SDFR protocol, the energy consumption, network stability, and sensor-forward-connected range are considered. Compared with the random method, the SDFR protocol can save the energy and keep the network stable with theoretical and experimental simulations.
