Abstract: To protect the source location privacy in wireless sensor network and realize the balance of security and network energy consumption, this paper proposes a source location privacy preservation Routing Protocol Based on Multi-Path（RPBMP）. The protocol is based on multi-path selection and multiple relay nodes, can greatly increase the routing path between source node and base station, and extend the security time. Theoretical analysis and simulation results show that RPBMP can improve the location privacy protection performance of the source node without significantly increasing the energy consumption.
