Abstract:Â Wireless Sensor Networks are emerging as a promising platform for a variety of application areas. However many security issues impede its wide deployment in practice. The nature of the wireless communication, the fast deployment practices, and the hostile environments where they may be deployed, make them vulnerable to a wide range of security attacks. Among these attacks wormhole attack plays a major role. This paper analyzes and finds solution for wormhole attack and enhances the detection of innovative packets which is possibly done by DAWN. We rigorously prove that DAWN guarantees a good bound of successful detection rate. We perform analysis on the resistance of DAWN against collusion attacks. DAWN does not rely on any location information, global synchronization assumptions or special hardware/middleware. It is only based on the local information that can be obtained from regular network coding protocols, and thus the overhead of our algorithms is tolerable. The experimental results have verified the effectiveness and the efficiency of DAWN.
