Secure Probabilistic Location Verification for Wireless Sensor Networks

Security is one of the important factors for any Wireless Sensor Networks application. Location verification system provides that security for retrieving data from Wireless Sensor Networks application. Previous System requires group deployment knowledge of sensors or depends on highly expensive, dedicated hardware because of these requirement it is very expensive. In this paper location verification system with trusted token analyzer and Attack resistant location estimation scheme in secure manner is proposed. This system provides highly feasible true location estimation of sensor node with low cost and reduces false estimation due to attacks such as malicious attack, wormhole attack, pollution attack etc.
