TECHNOLOGY Defend the Locations in WSN from Snoopers

In detector network several protocols are exploitat ion for privacy and preservation of knowledge again st aggressor. Such connected data will be manipulate b y associate mortal to derive sensitive data like th e locations of observe objects and information receivers within th e field. Attacks on these elements will considerabl y undermine any network application.The snooper, is realistic a nd may defeat these existing technique. It initial formalizes the situation privacy problems in detector networks und erneath this robust mortal model and computes a bound on the communication overhead required for achieving a given level of location privacy. It proposes 2 techniq ues to produce location privacy to sender-location privacy —periodic assortment and sender simulation—and 2 techniques to produce location privacy to Receiver-location pr ivacy—Receiver simulation and backbone flooding. These techniques give trade-offs between privacy, communication value, and latency. Use of those propose tec hniques, it improves location privacy for each sender and recei ver locations.
