A Token Based Approach for Detecting Replica Node Attack in Static WSNs

Geetha C, Ramakrishnan M

Wireless sensor network is a network of sensor nodes. Nowadays a common issue in this network is security. The sensor nodes are power constrained; resource constrained and so easily attacked by malicious nodes. One of the major attacks is node replica attack. A node captures the id and cryptographic information of another node and replicates this node and distributed in the network which will lead false data transmission, leaking the data, jamming the data transmission etc. The proposed algorithm is based on a token which is generated by the source node. This algorithm shows efficiency in detecting the clone nodes easily and simply. All the messages are combined into one token and so this reduces the number of message transmission also. The simulation results shows that the detection rate is high and the communication overhead is less compared with other existing algorithms.
