Wireless Sensor Networks: “A Review on Replica Detection Techniques”

Wireless sensor networks generally works on the principle of multipath propagation where multiple sensor nodes work together to collect the data and then transfer the sensed data to the sink node or base station. A replica node is the major issues in wireless sensor network is replica formation/creation. In this situation, an opponent node captures all the details of the original node and places the duplicate nodes in the network to get all the information related to the network. This paper presents a review of replica detection algorithm in wireless sensor network.
