Abstract:With the aim of addressing the problem of high overhead and unstable performance of the existing Source Location Privacy (SLP) protection algorithms, this paper proposes an efficient algorithm based on Circular Trap (CT) which integrates the routing layer and MAC layer protocol to provide SLP protection for WSNs. This algorithm allocates time slots for each node in the network by using Time Division Multiple Access (TDMA) technology, so that data loss caused by channel collisions can be avoided. At the same time, a circular trap route is formed to induce an attacker to first detect the packets from the nodes on the circular route, thereby moving away from the real route and protecting the SLP. The experimental results demonstrate that the CT algorithm can prevent the attacker from tracking the source location by 20% to 50% compared to the existing cross-layer SLP-aware algorithm.
