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 within a designed STaR area located around the SINK node. The STaR area is large enough to make it unpractical for an adversary to monitor the entire region. Furthermore, this routing protocol ensures that the intermediate node is neither too close, nor too far from the SINK node in relations to the entire network. While ensuring source location privacy, our simulation results show that the proposed scheme is very efficient and can be used for practical applications.
