Detection of Wormhole Attack using Hop-count and Time delay Analysis

Abstract

Abstract- MANET, due to the nature of wireless transmission, has more security issues compared to wired environments. In this paper we specifically considering Tunneling attack which does not require exploiting any nodes in the network and can interfere with the route establishment process. Instead of detecting suspicious routes as in previous methods, we implement a new method which detects the attacker nodes and works without modification of protocol, using a hop-count and time delay analysis from the viewpoint of users without any special environment assumptions. The proposed work is simulated using OPNET and results showing the advantages of proposed work. Index Terms- Ad hoc network, hop-count analysis, network security, Tunneling attack
