Abstract
A MANET is a peer to peer multi hop mobile wireless network that has neither a fixed infrastructure nor a central server some nodes may selfishly decide only to cooperate partially, or not at all, with other nodes. The mobility and resource constraints of mobile nodes may lead to network partitioning or performance degradation. Several data replication techniques have been proposed to minimize performance degradation. Most of them assume that all mobile nodes collaborate fully in terms of sharing their memory space. Malicious nodes are hard to detect using watchdogs, as they can intentionally participates in network communication with the only goal to hide their behavior from the network. In paper, we develop a collaborative contact based watchdog CoCoWa detection algorithm that considers partial selfishness and novel replica allocation techniques to properly cope with selfish replica allocation. In this project,we define solid privacy requirements regarding malicious attackers in MANET. Then we propose and implement a new intrusion detection system named Enhanced Adaptive ACK specially designed for MANET s. E ACK demonstrates higher malicious behaviour detection rates in certain circumstances while does not greatly affect the net work performance.
