Survey of Detection of Sinkhole Attack in Wireless Sensor Network

Wireless Sensor Network (WSN) is emerging as a prevailing technology due to its wide range of applications in military and civilian domains. These networks are easily prone to security attacks. Unattended installation of sensor nodes in the environment causes many security threats in the wireless sensor networks. There are many possible attacks on sensor network such as selective forwarding, jamming, sinkhole, wormhole, Sybil and hello flood attacks. Sinkhole attack is among the most destructive routing attacks for these networks. It may cause the intruder to lure all or most of the data flow that has to be captured at the base station. Once sinkhole attack has been implemented and the adversary node has started to work as network member in the data routing, it can apply some more threats such as black hole or grey hole. Ultimately this drop of some important data packets can disrupt the sensor networks completely. This paper focuses on the various methods that can be implemented to overcome this attack likeLocation Based Compromise Tolerant Security Mechanism, Hop Count Monitoring Scheme and through Non Cryptographic Method of Sinkhole Attack Detection.
