An Adaptive Approach for Detection of Blackhole Attack in Mobile Ad hoc Network

Security is an essential component for mobile ad hoc network (MANET). In order to provide security against attacker, researchers are working specifically on the security challenges in MANETs, and many techniques are proposed for secure routing protocols within the networks. Our proposed work presents a more efficient solution for detecting a black hole attack with less communication cost in the MANET, which is particularly vulnerable compared to infrastructure-based networks due to its mobility and shared broadcast nature. As an adversary can successfully deploy black hole attack in the network. It can be seen that proposed work is more secure than the existing solutions. We also compared its performance to standard AODV routing protocol. The experimental results show that the proposed approach is better than standard AODV.
