摘要：Sensor networks are composed of a number of sensor nodes with limited resources and used in application such as environment monitoring and object tracking. This allows a situation where the adversary can compromise one sensor node, fabricate many replicas having the same identity (ID) from the captured node, and place these replicas back into strategic positions in the network for further malicious activities. This is called clone node attack. The proposed system focuses on clone node attacks. Several clone node detection schemes have been proposed in the literature to defend against such attacks in static sensor networks. XED and EDD have been implemented for the detection of clone nodes. In XED and EDD, each node not only detects the replicas by its own effort, but also can revoke the replica in a communication-efficient way. XED algorithm have storage overhead of O(n). EDD algorithm's detection time increases based on the number of neighbor nodes. SED and BRSL algorithms are proposed to overcome the above mentioned drawbacks and to detect malicious anchor nodes. BRSL algorithm effectively distinguish malicious anchor node and increases detection accuracy. This algorithm improves localization accuracy.
