Neighbour Node Ratio AODV (NNR-AODV) Routing Protocol for Wormhole Attack Detection in Manets

This paper aimed at the detection of wormhole attack and proposed a new method called as Neighbour Node Ratio Adhoc On demand Distance Vector Routing (NNR-AODV). NNR-AODV is an extended version traditional AODV routing protocol. The calculates neighbour node count for every based on that it will decide whether present or not. Furthermore, able to detect both external internal attacked nodes. Also, derived Neighbor Threshold value which cumulative distances between nodes in attack. For experimental validation, we have accomplished extensive simulation performance measured through Number bogus links, Detection rate, False positive Rate, Packet delivery ratio loss ratio. obtained results shown superior attacks than existing methods.
