The privacy threats of Wireless Sensor Networks (WSN) can be classified into two broad categories: content privacy and context privacy. Source location privacy comes under the purview of contextual privacy, in which the context information, like the location of the source node, its identity; or temporal information like the time and duration of transmission, is kept hidden from unintended users. Content privacy generally relies on data encryption for providing data security in WSN. This approach of encryption can become counter-productive because cryptographic algorithms are computationally intensive and can deplete the scarce energy resources of the WSN.
