Wireless sensor networks (WSNs) have been widely used in many areas for critical infrastructure monitoring and information collection. While confidentiality of the message can be ensured through content encryption, it is much more difficult to adequately address source-location privacy (SLP). For WSNs, SLP service is further complicated by the nature that the sensor nodes generally consist of low-cost...
In wireless sensor networks (WSNs), providing source-location privacy through secure routing is one of the most prosperous techniques. In this paper, we propose a routing technique to provide adequate source-location privacy with low energy consumption. We introduce this technique as the Sink Toroidal Region (STaR) routing. With this technique, the source node randomly selects an intermediate node...
