Performance Evaluation of AODV and AOMDV Routing Protocols Under Collaborative Blackhole and Wormhole Attacks

Abstract

Mobile Ad hoc Network (MANET) is easy to be attacked than wired networks due to its characteristics of open network topology, high mobility, lack of physical security and independent management. This paper analyzes the impact of routing attacks on the performance of the AODV and AOMDV routing protocol under several collaborative routing attack scenarios (blackhole and wormhole). We conclude that AOMDV is better than AODV in case of collaborative attacks and we show that collaborative Blackhole and Wormhole attacks can affect much performance of the network, especially in the case when we do not recognize the location area of malicious nodes.
