Abstract -
Most of the MANET IDs are referring watchdog scheme to thwart the malicious attacks, but this scheme fails to detect such type of destructive actions with the presence of ambiguous collisions, receiver collisions, limited transmission power, false misbehavior report, collusion and partial dropping. Enhanced adaptive acknowledgment EAACK is designed to handle three of the six weaknesses of the watchdog scheme namely false misbehavior, limited transmission power, and receiver collision by using the techniques ACK, 2-ACK, and misbehavior report identification MRI. Which is not fully efficient to resolve all the problems? This paper introduces digital signature with AOMDV to avoid forging acknowledgment packets from attackers. AOMDV throughput and routing overhead is better than and DSR protocols for the performance metrics like Packet Delivery Ratio and Routing Overhead.
