Prevention, Reduction and Recognition of Wormhole Attack by Coordination in the Wireless Adhoc Network

Abstract

The adhoc networks are the wireless networks that are briefly established and do not need to be mounted as infrastructure less network. These adhoc networks share a similar wireless medium and lack central coordination that makes them more vulnerable than wired networks to attacks. The intruder senses the packets in terms of bits and tunnels them (possibly selectively) from one location to another location in case of wormhole wireless attack it then sends them back to the network. This kind of wormhole attacks can be a major threat to wireless security systems based on location and adhoc networks per se. To provide strong protection, packet dynamic data can be changed to find a solution over wormhole attack. Wireless election algorithms have chosen the coordinator node to tackle the wormhole attack. The coordinator node's functions are to observe, isolate and prevent further attacks. The simulation experiments were conducted in this context to check the performance in various situations. We have identified from these experimental results that the suggested wireless protocol is adapted to improve the protection of resource-restricted wireless sensor networks.
