In wireless sensor networks(WSN) source location privacy protection issues,aiming at hop by hop backtracking attacker w ith the ability of local traffic analysis,a source location privacy routing protocol RAPFPR based on random angle and probability forw arding is proposed.The protocol is mainly divided into tw o 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 forw arding routing phase.The protocol of the phantom nodes can evenly distributed around the true source node,and probability forw arding routing greatly reduces the probability of overlapping path,increased the difficulty of hop by hop reverse attacker.Compared w ith the existing privacy protection scheme,simulation results show that under the premise of w ithout significantly increasing the communication overhead,this protocol can effectively prolong the average netw ork safety time and has a very good privacy protection performance.
