Sweety Goyal, Harish Rohil . Securing MANET against Wormhole Attack using Neighbor Node Analysis. International Journal of Computer Applications. 81, 18 ( November 2013), 44-48. DOI=10.5120/14227-2478
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.
