摘要：
Wireless sensor networks are widely deployed to monitor valuable objects. Attackers can find out the source node by hop-by-hop backtracking strategy. So, we need provide source anonymity for sensor networks. This paper examines that the phantom source nodes generated by the existing source location privacy preservation protocols are near the real source. So they can not protect the real source node well. As such, this paper proposes a protocol called PUSBRF(Source Location Privacy Preservation Protocol in Wireless Sensor Network Using Source-Based Restricted Flooding). And based on PUSBRF, it proposes another protocol called EPUSBRF (Enhancement Source Location Privacy Preservation Protocol in Wireless Sensor Network Using Source-Based Restricted Flooding) under the consideration of an attacker with enhancement visual ability. Simulation results show that compared to the existing protocols, the new protocols provide strong source location privacy preservation and the average safety period is increased by nearly one order of magnitude.
