Impact of black hole attack on multicast in ad hoc network (IBAMA)

Abstract

In wireless and distributed nature of Ad hoc networks, security has become a more sophisticated problem than security in other networks, due to the open nature and the lack of infrastructure of such networks. This paper is based on Blackhole attack. This attack node first needs to invade into the multicast forwarding group. It then absorbs all the data packets in the network and drops fully or partially. So, that the destination node does not get the data packets fully and this will affect the packet delivery ratio (PDR). In this paper, the goal is to measure the impact of Balckhole attack and their node positions which affect the performance metrics of packet delivery with respect to three scenarios: Black hole attack node near sender, blackhole attack node near receiver and anywhere within the network. The performance of PDR with respect to above three scenarios is also compared.
