Abstract
Wireless sensor networks (WSNs) consist of a large number of sensor nodes which are deployed without selfdefense capability. The node replication attack is a specific attack mode to WSN and the detection of node replication attacks in WSNs became a fundamental problem. In this paper, we proposed a range-assisted distributed protocol (RADP) to detect node replication attacks in WSNs. The contributions of this work are threefold. First, we showed that the known solutions do not completely meet our requirements. Second, we tried to use wireless ranging information to detect node replication attacks. Third, we proposed a novel protocol for the detection of node replication attacks and Extensive theoretical analysis and experiment verified that it can maintain a high detection probability with low accuracy ranging among nodes. Keywords-wireless sensor networks; replication attacks; detection protocol; range-assisted.
