Abstract

Mobile ad hoc networks (MANETs) are structure-less networks in which the mobile nodes are communicate wirelessly with each other’s. This wireless channel makes the MANETs vulnerable against different types of attacks. Wormhole is one of these attacks, according to which, two active attackers create a virtual private communication tunnel; reduce message normal stream and pretend two non-neighbored nodes as neighbors. In this way, the path between these two nodes is pretended as the shortest possible route between the source and the destination. Thus, all data packets passing through this route can be eliminated by these attacker nodes. This paper inspires from human immune system to design a defense mechanism against wormhole attack, called WAAIS (Wormhole Attack Artificial Immune System). In this proposed mapping, all unsecure routes, are considered as antigen. These unsecure routes are recognized by some rules, which are considered as antibody. The simulation results show that WAAIS outperforms WormPlanar and AODV in terms of packet delivery rate, average end-to-end delay and drop packets rate.
