MANET does not require a fixed network infrastructure. The open medium and wide distribution of nodes make MANET vulnerable to security attacks. Hence, it is crucial to develop an efficient intrusion detection system. In this paper, a novel system called DEAACK - Defensive Enhanced Adaptive ACKnowledgement specially designed for MANET is used. This scheme overcomes the hurdles faced by the watchdog scheme. Packet dropping attack has always been a major threat in security in MANET and it is overcome successfully EAACK. DEAACK proposes to use multiple key generation mechanism to eliminate forged acknowledgement packets.
