Prevention of Wormhole Attack in WSN using Energy Optimized Scheme based on Hop

Computer Engineering

Sensor Network is infrastructure-less network in which communication takes place between mobile nodes, packet is transmitted with the help of intermediate nodes. Nodes are capable of moving free in the network, they can leave or join the network when it is needed. Hence with the dynamic changing nature of Sensor network is vulnerable to various security attacks. These attacks hinder the network performance Mobile ad hoc networks, security is considered as one of the critical issue. Sensor network are comprised of nodes that must cooperate to dynamically establish routes using wireless links. Routes may involve multiple hops with each node acting as a host and router. Since ad hoc networks typically work in an open entrusted environment with little physical security, they are subject to a number of unique security attacks like wormhole attack. The wormhole attack is considered to be a serious security attack in multi-hop ad hoc networks. Unlike many other attacks on ad-hoc routing, a wormhole attack cannot be prevented with cryptographic solutions because intruders neither generate new, nor modify existing, packets, but rather forward existing ones. In this paper work is concentrate on the noxious conduct of AODV under wormhole attack. On the premise of previous information check and zone data we identify wormhole and for counter active action we stream normal way node id in the system. In this paper a simple technique to effectively detect wormhole attacks without the need for special hard ware and/or strict location or synchronization requirements is proposed. The proposed technique makes use of variance in routing information between neighbors to detect worm holes. The proposed approach have higher packet delivery ratio, lower routing overhead, lower energy consumption and higher throughput.
