Securing MANET against Wormhole Attack using Neighbor Node Analysis
Sweety Goyal, Harish Rohil · International Journal of Computer Applications · 2013
In mobile ad hoc networks (MANETs) security is of major concern because of its inherent liabilities.The characteristics of MANETs like infrastructure less network with dynamic topology pose a number of challenges to security design.There is an increasing threat of attacks in MANET.Wormhole attack is one of the security attacks on mobile ad hoc networks in which a pair of colluding nodes make a tunnel using a high speed network.This paper focuses on providing a solution for secure transmission through the network and proposes a neighbor node analysis approach to identify wormhole attack and removes wormhole link in MANET.The proposed work is simulated using NS-2 and is analyzed using certain parameters such as throughput, loss rate, delay rate.
