Detection of Vulnerability Network Traffic and Relica Node Attak in Wireless Sensor Network
In Wireless Sensor Networks, an adversary can capture and compromise sensor nodes, make replicas of them and then mount variety of attacks with these replicas. These replica nodes are dangerous because they allow the attacker to leverage the compromise of a few nodes to exert control over much of network. Several replica node detection schemes have been proposed in the literature to defend against such attacks in static sensor networks. However, these schemes rely on fixed sensor locations and hence do not work in mobile sensor networks, where sensors are expected to move. In this paper, the GNAVE algorithm is proposed to find replica node and vulnerability metric in wireless sensor network.
