A Survey on Wormhole Attack Detection Algorithm

Wireless sensor networks are the infrastructure- less network which are vulnerable to various routing attacks. This in- turn degrade the performance of the sensor network and information are received by wrong sinks. In this case, the wormhole attack poses a serious threat in compromising sensor nodes and adds new set of malicious nodes to the network. Hence the low latency links are established and packets are replayed between two nodes. To detect and avoid this wormhole attack, various algorithms are presented. This paper emphasis on the study of these algorithms and suggest the best algorithm to detect and avoid wormhole attacks in wireless sensor networks.
