Wireless Sensor Networks (WSNs) consist of low-cost, resource-constrained sensor nodes and a designated node called a sink which collects data from the sensor nodes. A WSN can be used in numerous applications such as subject tracking and monitoring, where it is often desirable to keep the location of the subject private. Without location privacy protection, an adversary can locate the subject. In this paper, we propose an algorithm that tries to keep the subject location private from a global adversary, which can see the entire network traffic, in an energy efficient way.
