NNA ALGORITHM TO PREVENT BLACKHOLE ATTACK
Chander Diwaker, Sunita Choudhary · 2013
Mobile Ad hoc network is a collection of nodes which are self configuring and connected by wireless links automatically. One of the principle routing protocol used is AODV protocol. The security of AODV protocol is compromisd by a particular type of attack called Black hole attack. In this paper, we proposed Neighbor node analysis algorithm to prevent black hole attack which will provide a secure path that may be wider than shortest path. But it will provide high throughput and reduce the loss over the network. Computer simulation using NS2 shows that our algorithm provides better packet delivery, decreased packet loss rate and reduced packet delay.
