Local Monitoring based Reputation System with Alert to Mitigate the Misbehaving Nodes in Mobile Ad Hoc Networks

The researchers have proposed several local monitoring based reputation mechanisms to identify and isolate the misbehaving nodes in Mobile Ad hoc Networks. The simulation results of these mechanisms shows a considerable amount of improvement in overall network throughput but at the expense of false detection of a good node as a misbehaving one by the monitoring node due to lack of alerting the source of the packet about misbehaving link. So there exists a need for designing a new mechanism to minimize such false detections. This paper proposes a Local Monitoring based Reputation System with Alert [LMRSA] mechanism to minimize the effect of false detections without compromising the overall network performance. The simulation results were compared with the existing model that lacks the forwarding traffic rejection and alert mechanism.
