摘要：There are many replica detection schemes in the past for the static sensor networks b ut due to the unattended nature of wireless sensor networks, an adversary can capture and co mpromise sensor nodes, make replicas of them, and then mount a variety of attacks with these replicas. These replica node attacks are dangerous because they allow the attacker to leverage the compromise of a few nodes to exer t control over much of the 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 work, our aim is to propose a fast and effective mobile replica node detection scheme using Sequential Probability Ratio Test. To the best of o ur knowledge, this is the first work to tackle the p roblem of replica node attacks in mobile sensor networks. We show analytically and through simulation experiments that our scheme detects mobile replicas in an efficient and robust manner at the cost of reasonable overheads.
