Analyse impact of malicious behaviour of AODV under performance parameters
Martin Parmar, Harikrishna B. Jethva · 2014
Mobile Adhoc Network is fully autonomous in which mobile node plays dual role as node itself and as a router to forward packets. Fully distributed operation in which there is no any centralized authority. Network structure are fully dynamic in which every nodes is free to move anywhere with different speed. As distributive and dynamic approach of MANET, security often needs to be considered as an important one. There are also some more critical issues like packet loss due to mobility and also cause link breakage. In this paper we focus on malicious behavior of AODV under attacks which are mainly WormHole, BlackHole and GrayHole in network layer. In our proposed work, we only analyzed behavior of BlackHole and GrayHole attacks under AODV protocol and show the effects of both on network layer. We have also tested malicious behavior of AODV under above attacks using various performance parameters like throughput, packet delivery ratio, normalized network load and end to end delay using different simulation parameters.
