An Two Dimension detection to node replication attacks in mobile sensor networks

The node replication attack is one of the notorious attacks which can be easily launched by the adversary in wireless sensor networks. A lot of literatures have studied to mitigate the node replication attack in static wireless sensor networks. However, the detection to the replica in the mobile sensor networks is more difficult to implement. To avoid centralized detection, some existing schemes try to identify a replicated node by meeting mobile nodes with the same ID but different characteristics. To facilitate discovery of the contradictory characteristics, a hybrid detection including local detection and global detection is proposed — Two Dimension Detecting Scheme. And for different malicious activity, we proposed a detection scheme can deal with different attacks — Advanced Two Dimension Detecting Scheme. The local detection is performed in a local area much smaller than the whole deployed area to improve the meeting probability of the contradictory locations. Furthermore, the distant replicated nodes can also be efficiently detected by the global detection. The complementary two levels of detection achieve quick finding of the replicas with reasonable overhead.
