DETECTION OF VIRTUAL LINK ATTACK IN WIRELESS AD-HOC NETWORK

摘要

As the popularity of mobile device and wireless networks significantly increased over the past years. Wireless ad-hoc networks has now become one of the most vibrant and active field of communication and networks. Due to different challenges, the special features of MANET bring this technology great opportunistic together. In this study, the existing approach is AODV routing protocol without any detection mechanism. But proposed approach is AODV routing protocol with detection mechanism. The implemented mechanism detects malicious node that launch the proper attack in virtual link attack. The goal of virtual link attack is, to create virtual symmetric link between two nodes, which may leads to data packet loss. In order to combat this problem I implemented the mechanism for avoiding this attack.
