In wireless sensor networks(WSN) source location privacy protection issues, aiming at hop by hop backtracking attacker with the ability of local traffic analysis, a source location privacy routing protocol RAPFPR based on random angle and probability forwarding is proposed. The protocol is mainly divided into two phases: the true source node according to the random angle and distance directed routing phase and the phantom node to the base station based on probability forwarding routing phase. The protocol of the phantom nodes can evenly distributed around the true source node, and probability forwarding routing greatly reduces the probability of overlapping path,increased the difficulty of hop by hop reverse attacker. Compared with the existing privacy protection scheme, simulation results show that under the premise of without significantly increasing the communication overhead, this protocol can effectively prolong the average network safety time and has a very good privacy protection performance.

Key words: wireless sensor networks; source location privacy; random angle; probability forwarding; safety time
