Efficient and Distributed Detection of Node Replication Attacks in Mobile Sensor Networks

In this paper, we study the challenging problem of node replication detection. Although defending against node replication attacks demands immediate attention, only a few solutions were proposed. In this paper, an Efficient and Distributed Detection (EDD) scheme and its variant, SEDD, are proposed to resist against node replication attacks in mobile sensor networks. The characteristics possessed by EDD and SEDD include (1) Distributed Detection; (2) Efficiency and Effectiveness; (3) Individual Detection; (4) Network-Wide Revocation Avoidance. Performance comparison with known methods are provided to demonstrate the efficiency of the EDD and SEDD schemes.
