摘要：Recent advances in portable computing and wireless technologies are opening up exciting possibilities for the future of wireless mobile networking. A Mobile Ad hoc NETwork (MANET) is one of the most important and unique applications among all the contemporary wireless networks. It consists of mobile platforms which are free to move arbitrarily. They do not need a fixed infrastructure and the network topology may dynamically change in an unpredictable manner. Because of these features it is now popular among critical mission applications like military use or emergency recovery. But security is always an issue for MANET. Due to the node’s lack of physical protection, malicious attackers can easily capture and compromise nodes to achieve attacks. In particular, considering the fact that most routing protocols in MANETs assume that every node in the network behaves co-operatively with other nodes and presumably not malicious, attackers can easily compromise MANETs by inserting malicious or non-cooperative nodes into the network. Furthermore, because of MANET’s distributed architecture and changing topology, a traditional centralized monitoring technique is no longer feasible in MANETs. In such case, it is crucial to develop an intrusion-detection system (IDS) specially designed for MANETS. Here we proposes a highly efficient and secure IDS by finding out the possibilities of clustering techniques in the existing Enhanced Adaptive ACKnowledgement (EAACK) scheme to further reduce the network overhead and increase the scalability in EAACK system. The main objective of the proposed system is to detect the presence of malicious nodes in the network with less routing overhead and also improving the reliability, throughput and stability of the network efficiently
