Location Privacy in Wireless Sensor Networks

The insecure atmospheres makes easy for an adversary to eavesdrop the network in a wireless sensor network. An eclectic collection of protocols are available for providing content privacy but the contextual information remains unprotected. So an adversary can use this contextual information to carry out attack on source node or the sink node in sensor network. The current approaches for location privacy protect the sensor network only against a local adversary. In this locale to provide location privacy for source node intervallic gathering and source imitation methods are proposed. Also for preventing sink node from adversary sink imitation and backbone flooding methods are proposed. These proposed approaches provide location privacy against global adversaries.
