Wormhole Attack Avoidance Technique in Mobile Adhoc Networks

Abstract

Security is an essential service for wired and wireless network communication. This work concerned with a particularly sever security attack that affects the ad hoc networks routing protocols, called "wormhole attack". There are many solutions to detect and prevent this attack like packet leashes, cluster base, hop count analysis etc., but none of them is perfect solution. This paper contains a proposal for new technique for wormhole avoidance. Proposed technique has been implemented with NS2 simulator over the DSR protocol. This technique for wormhole avoidance addresses the malicious nodes and avoids the routes having wormhole nodes without affecting the overall performance of the network. The performance metrics used for evaluating network performance are jitter, throughput and end to end delay. The performance of proposed techniques is good.

Detection and Prevention of Wormhole Attack in MANET Using DSR Protocol

“…When wormhole nodes are introduced in the network, they try to validate its neighbouring nodes that they are its legitimate neighbours and the route through these nodes also exist. [1] In the figure 1, it is shown that when source and sink want to communicate, S-A-B-C-D route is followed which is a normal route. When wormhole nodes X and Y are introduced into the network, they lure their neighbours S and D that they are their immediate neighbours and have a path between X and Y.…”
