In this study, we analysed effect of the black hole in an AODV network. For this purpose, we implemented an AODV protocol that behaves as black hole in NS-2.35. We simulated 9 scenarios in this book on 6, 20 and 30 nodes. In every scenario we implemented network performance after and before multiple black hole attacks. After that simulated IDSAODV solution with same scenarios to observe AODV behaviour versus multiple black hole attacks under this proposed solution. First, investigated effects of black hole attack on network ...

In this study, we analysed effect of the black hole in an AODV network. For this purpose, we implemented an AODV protocol that behaves as black hole in NS-2.35. We simulated 9 scenarios in this book on 6, 20 and 30 nodes. In every scenario we implemented network performance after and before multiple black hole attacks. After that simulated IDSAODV solution with same scenarios to observe AODV behaviour versus multiple black hole attacks under this proposed solution. First, investigated effects of black hole attack on network performance which this attack increase number of drop packets and decrease packet delivery ratio, even with adding the number of black hole nodes, drop packets increase more and packet delivery ratio drops-off. After implementing IDSAODV on the network, drop packets decreased and packet delivery ratio improved. Other benefits of this solution are that the proposed solution requests minimum modification on AODV. It doesn't change packet format and can work together with AODV protocol and does not request additional routing overhead. Black hole attack increase number of drop packets and decrease packet delivery ratio on MANET performance.After applying multiple numbers of black hole nodes on the network, drop packets will be more increased and packet delivery ratio drops-off.Implementing IDSAODV on the network, decreases drop packets and improves packet delivery ratio.IDSAODV solution requests minimum modification on AODV.IDSAODV doesn't change packet format and can work together with AODV protocol and does not request additional routing overhead.
