Abstract: In Mobile Ad hoc NETwork (MANET), the primary requirement is co-operative communication among nodes. Malicious nodes in a network may lead to attacks like Black Hole, Grey Hole and Wormhole attacks. In this paper, various routing schemes like Dynamic Static Routing (DSR), 2ACK, Best-Effort Fault-Tolerant Routing (BFTR) are considered and their behaviors against attacks are also examined. To deal with these attacks in these routing schemes, Enhanced Cooperative Bait Detection Scheme (ECBDS) that integrates the advantages of both proactive and reactive defense architecture based on DSR mechanism is designed. A malicious node can attract all packets by using forged Route REPly (RREP) packet to falsely claim fake shortest route to the destination and then discard these packets without forwarding them to the destination. ECBDS rejects the alarmed and detected malicious nodes in the initial stages. It outperforms the existing Cooperative Bait Detection Scheme (CBDS) mechanism in terms of Packet Delivery Ratio (PDR), Throughput and Routing Overhead.
