Location Privacy in Wireless Sensor Networks Using Anonymity

A sensor network comprised of multiple devices with sensing abilities and communications technologies. Location privacy is crucial in WSN. Information on the position of the events or location of the sink node can be an initial attention of the enemy. The location privacy aims to cover the position of the sensor that senses the data and makes it tough for an attacker to discover back to the node or location. Location privacy is sorted into two categories, i.e., source node privacy and sink node privacy. Anonymous communication is a core feature of location privacy in WSN because it used to hide the identity of critical sensor nodes. The proposed location privacy schemes provide a solution for node anonymity and location privacy in WSNs.
