Abstract

In a WSN, sink-node gathers data from surrounding nodes and sends it to outside world via a gateway. Therefore, its location information is important to both attacker and network operator. The former can launch attacks on a sink-node to steal information or damage it, while the latter must hide its location to ensure data’s safety, and physical protection. As the central point of failure, sink location protection is critical to the viability of the whole sensor network. However, existing work related to sink location protection only focuses on local traffic analysis attack. In this paper, we examine the sink location protection problem under a more powerful attack, the global traffic monitoring attack for the first time. In order to hide the sink location, a scheme based on packet sending rate adjustment (SRA) is proposed. By controlling the packet sending rate of each node according to the current number of source nodes, SRA conceals the real traffic volume generated by new source nodes and hence disguises the location of the sink. Theory analysis shows that SRA can protect the sink location against global traffic analysis attack effectively.
