Body-to-Body Network Routing Algorithm Based on Link Comprehensive Stability

As an important part of the emergency rescue system, Wearable Wireless Sensor Network (WWSN) has developed rapidly which can realize accurate, efficient and stable data transmission among users. In this paper, considering frequent changing topology of body-to-body network, a Robust Routing Algorithm Based on Link comprehensive Stability in Body-to-Body Network (RRLS) was proposed. The RRLS algorithm includes two parts: route discovery and route maintenance. In the process of route discovery, considering the moving speed and direction of nodes, the optimal route is selected using the designed link comprehensive stability parameter. Frequent human movement will cause link breakage. Therefore, we adopt the route maintenance scheme to repair the link in time. The simulation results show that the RRLS algorithm proposed in this paper has good performance in terms of delay, packet loss rate and energy consumption.
