The recent advancements in the field of wireless communications makes the mobile devices to communicate with each other in a self organized manner without relying on stable infrastructure. It requires cooperation between the mobile devices in order to find routes between them when the nodes are not in the communication range of each other. The misbehaving node comes into existence due to scarcely available resources such as battery, bandwidth and computational power. When the nodes collude to misbehave then it further makes the routing process difficult due to frequent network partitioning and it also degrades the overall network throughput. This paper proposes a Collaborative Polling based Routing Security Scheme to detect and isolate the colluding misbehaving nodes in mobile ad hoc networks. The proposed system employs a timeout approach to detect the active neighbors in the neighborhood before monitoring the transmissions which involves it. It ensures that the false detection of a good node as a bad one has been greatly reduced which in turn decreases the send buffer drop because of the availability of alternate routes. The simulation result shows that the measured parameters such as packet drop ratio and malicious drop has been reduced due to the efficient detection and isolation of misbehaving nodes. This paper also presents an analytical and simulation results of the impact of node misbehavior. [ABSTRACT FROM AUTHOR] |
