WDAP: Wormhole Detection and Avoidance Protocol for Mobile Ad-hoc Environment

Network security is an important criteria for wired and wireless communication. The advancement in wireless technologies and the high availability of wireless equipment in everyday devices is a factor in the success of infrastructure-less networks. MANETs are becoming more and more common due to their ease of deployment. The high availability of such networks and the lack in security measures of their routing protocols are alluring a number of attackers to intrude. In such environment, the presence of malevolent nodes may result in wormhole attacks. In this paper, a secured AODV-based routing scheme Wormhole Detection and Avoidance i.e. WDAP is proposed for mitigating such attacks. Implementation is performed in NS2 environment and results are provided to demonstrate the effectiveness of our approach, using the packet delivery ratio, Network throughput, Routing Overhead and the number of packets received by destination, as performance indicators.
