A New Combination Approach To Secure MANETS Against Attacks

In Wireless communications the traffic across a mobile ad hoc network (MANET) can be highly vulnerable to security threats. Because of the features like unreliability of wireless links between nodes, constantly changing topology, restricted battery power, lack of centralized control and others, the mobile ad hoc networks are more prone to suffer from the malicious behaviors than the traditional wired networks. Therefore, it becomes very much necessary to pay more attention to the security issues in the mobile ad hoc networks. In this paper a new combination approach, which combines three techniques is discussed. This approach is used to identify and prevent the malicious nodes exhibiting different network layer attacks and is compared with a nearest approach through the experimental results and analysis. Performance evaluation is done based on few network parameters.
