Source Routing Protocol Based on Bayesian Network for Wireless Sensor Networks

Multi-path routing is always the focus in wireless sensor networks. Either energy efficiency or QoS is taken into account in the existing multi-path routing, which makes the protocol not realize in both requirements. In this paper, the paths selection approach based on Bayesian network are introduced into the multi-path routing establishment, while two phase path selection mechanism according to Path ID and Path Ability respectively, are applied into the protocol. The simulation shows that BNSR is better than the other protocols on longivity and transmission delay.
