Hosny M. Ibrahim, Nagwa M. Omar, Ebram K. William . A Lightweight Technique to Prevent Wormhole Attacks in AODV. International Journal of Computer Applications. 104, 6 ( October 2014), 1-9. DOI=10.5120/18203-9328
Mobile ad hoc network (MANET) is vulnerable to many types of routing attacks due to its dynamic topology and the collaboration of MANET nodes in finding routing paths. The wormhole attack is considered one of the most threatening attacks. The most popular MANET routing protocols such as ad hoc on demand distance victor (AODV) are vulnerable to this security threat. In this paper, a lightweight technique is proposed to detect and prevent wormhole attacks in AODV using a mobile reliable backbone network. The backbone network monitors the behavior of MANET nodes to judge their reliability. The simulation results using NS2 show that the proposed technique can efficiently prevent wormhole attacks.
