Enhanced Secure Trusted AODV (ESTA) Protocol to Mitigate Blackhole Attack in Mobile Ad Hoc Networks

Blog Article

The self-organizing nature of the Mobile Ad hoc Networks (MANETs) provide a communication channel anywhere, anytime without any pre-existing network infrastructure.However, it is exposed to various vulnerabilities that may be exploited by the malicious nodes.One such malicious behavior is introduced by blackhole nodes, which can be sequal eclipse 5 battery easily introduced in the network and, in turn, such nodes try to crumble the working of the network by dropping the maximum here data under transmission.In this paper, a new protocol is proposed which is based on the widely used Ad hoc On-Demand Distance Vector (AODV) protocol, Enhanced Secure Trusted AODV (ESTA), which makes use of multiple paths along with use of trust and asymmetric cryptography to ensure data security.

The results, based on NS-3 simulation, reveal that the proposed protocol is effectively able to counter the blackhole nodes in three different scenarios.
