A robust trust aware secure intrusion detection in MANET

A mobile ad hoc network (MANET) is a self-configuring infra structure less network of mobile devices connected by wireless. Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Such networks may operate by themselves or may be connected to the larger Internet. As the importance of MANET increases day to day, the vulnerability issues in MANET is important to be considered. The main issue concerned with MANET is partial dropping, ambiguous collisions, collusion. The implementation of a new intrusion-detection system named Enhanced Adaptive ACKnowledgment (EAACK) specially designed for MANETs. Compared to previous approaches, This technique demonstrates higher malicious-behavior-detection rates in certain circumstances while does not greatly affect the network performances.
