A Novel Approach to Detect and Prevent Wormhole Attack in Wireless Sensor Network

Abstract

In our previous study [1] we discussed about Wireless Sensor Network (WSN) and also about wormhole attacks, those are possible in wireless sensor network. In this presented work the previously performed work is extended to find an optimum solution for the wormhole link prevention in the wireless sensor network. The proposed technique discover alternative route to the target node. Because the shortest path can has the malicious attacker. The implementation of the secure route discovery protocol is performed using NS2 and by modification of the AODV routing protocol. Finally the performance of the protocol is measured in terms of throughput. That demonstrates the effectiveness of the presented routing protocol.
