Abstract:
Security in Mobile Ad Hoc Networks (MANETs) is difficult to achieve because of the different attacks that might occur in the network, such as black hole attacks. In black hole attacks, the malicious node tries to attract most of the network traffic by advertising it has the best routing paths to the destination nodes, once the traffic is received by the black hole node, it simply drops the packets. This paper proposes an enhancement to Ad hoc On-Demand Distance Vector (AODV) routing protocol by employing effective policies to detect and avoid black hole nodes. The performance of the proposed scheme is evaluated using simulation. The obtained performance results indicate that the proposed AODV protocol achieves a significant improvement over both MI-AODV and the original AODV protocols, in terms of packet delivery ratio, dropped packets ratio, and overhead
