Trust Based Node Replication Attack Detection Protocol for Wireless Sensor Networks

The harmful attack against Wireless Sensor Networks (WSN) is Node Replication attack, where one or more node(s) illegitimately claims an identity, are also called clone attack due to identity theft. The Node replication attack can be exceedingly injurious to many important functions of the sensor network such as routing, resource allocation, misbehavior detection, This study proposes a method Randomized and Trust based witness finding strategy for replication attack detection mechanisms in wireless sensor networks (RTRADP) with trust factor. Resilient to malicious witness and increased detection rate by avoiding malicious witness selection. Performances are compared with the existing witness finding approach and how the malicious witness drops the claim without processing and how those malicious witnesses are avoided with trust based approach.
