Secure co-operative neighbour-based approach for detection and prevention of black hole attack in wireless mobile ad-hoc networks

Abstract

Mobile ad-hoc networks are infrastructure-less, temporary networks which are exposed to routing attacks. Black hole attack is a routing attack formed by dropping all the received packets by a malicious node. To ensure the security and strength of MANETs a secure and effective mechanism is obligatory. This paper presents Secure Cooperative Neighbour-Based Approach in AODV to perceive and circumvent the black hole attack from the start of the network. This approach enables every node to exchange information with its neighbour using a secure, efficient and quick detection process against routing attacks by taking an alternative route on finding an attacker. This approach is able to avoid the black hole nodes and improve the performance of the system as observed in the simulations under ns2.
