Detection of Sinkhole Attack based on Analysis of Routing Behavior in an AODV Routing Environment

Wireless Sensor Networks (WSN’s) one of them most prevalent technology emerging in various fields. It consist of a multiple/variable number of sensor and autonomous mobile nodes. Due to low-cost, energy efficiency, easy implementation WSN’s technology becomes popular therefore chances of attack on wireless network also increases. Sinkhole attack one of the most devastating security thread in the wireless sensor networks that disrupt the working of routing protocol. In this attack, a sinknode (attacker node) propagates the forge routing message to its neighbour that it exist in the shortest path to send the packet to the destination. Once a sinknode get a access on network data it may perform either selective forwarding, alter packet or drop packet. There are already various work have been done to detect the sinkhole attack such as based on redundancy mechanism, Hop-Count monitoring, a novel detection mechanism etc. In this paper we proposed a technique to detect a sinkhole based on the analysis of routing behaviour. This technique elevates the performance in terms of detection rate which is proved by simulation.
