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...
