Abstract
Source location privacy (SLP) in wireless sensor networks (WSN) intends to protect the location privacy of monitoring objects, as the resources of WSN are limited, the essence of the SLP is to balance the security and energy-cost. Among the existing solutions, the scheme based on random walk (DROW) is most attractive. However, DROW didn’t consider the balance of each node’s energy consumption and the safety period is unstable. What’s more, it didn’t change the data flow either. To solve these problems, in this paper, we put forward an energy-aware location privacy routing protocol which consists of two parts: non-repeat polling routing protocol and strategy of fake messages based on energy-aware. On the premise of not influence the network lifetime seriously, we make full use of the high-energy nodes, strength the security of the network and change the data flow. Simulation results verify that we can provide higher stability as the variance of our protocol is only about one over forty of that based on random-walk. Meanwhile, more nodes participate in packets transmission so the energy consumption is balanced and safety period is extended by 20 % to 30 %.
