Abstract:
Mobile Ad-hoc Networks (MANETs) are widely used nowadays. Because of its characteristics like open medium, dynamic topology, being infrastructure less and lack of centralized monitoring, MANET is vulnerable to a wide range of attacks like blackhole and grayhole. Blackhole and grayhole attacks refer to the attacks that breach the security by performing packet forwarding and routing misbehavior and cause denial of service in MANETs. In this paper, we proposed two improvements to Cooperative Bait Detection Scheme (CBDS), we reduced both the false-positive rate in detection and the routing overhead. The proposed method (called Modified CBDS) employs Network Simulator-2 (NS-2) to validate the effectiveness under different scenarios. Simulation results show modified CBDS has a better performance in terms of throughput, end-to-end delay and energy consumption
