In order to improve the issue that the existing sink location privacy protection algorithms have lower safety period, sink location privacy protection algorithm based on tangential path in WSN is proposed. Sink determines circular security area, source nodes transmit real data packets through tangential path. Tangent point retransmits them to the sink and generates fake data packets through the original tangent path. In addition, fake sinks are randomly selected outside the security area by normal distribution model, and intersection nodes send fake packets to these fake sinks. Theoretical analysis and simulation results show that this algorithm can improve security period and achieve balance between sink location privacy protection and network energy consumption compared with the existing sink location privacy protection algorithm.
