RTT Based Wormhole Detection Using NS-3

Battery driven devices are need more routing strategy and their caring to safe against attack. WSN is also vulnerable to attack like wormhole, in which a malicious node captures packets from one location (or from intermediated path) in the network, and channelized it to the wrong direction towards another malicious node at a remote point, that recursively replays it again or start dropping. A wormhole tunnel can actually be useful if used for forwarding all the packets. However, in its malicious personification, it is used with violent nodes to suppress the correct operation of ad hoc and sensor network routing protocols. In this article a RTT estimator based wormhole detection mechanism has been proposed to identify wormhole tunneling attack in MANET. Proposed method has been evaluated and simulated using NS-3 simulator. Obtained results shows our enhance mechanisms using RTT estimator works efficiently and able to detect all the wormhole suspicious activity in wireless network. For effective simulation of wormhole, a wormhole tunnel has been create using AODV routing protocol then detection mechanism bas been enabled in conjunction with RTT estimation on the nodes.
