Mobile Ad-hoc NETwork (MANET) is a temporary infrastructure less network. This network is formed by combining some set of wireless mobile hosts. The host is called as a node which dynamically establishes their own network. In MANET all the nodes operates in cooperative fashion. Due to their certain inherently vulnerable characteristics, there are many possibilities of the attacks in MANET. Every time intrusion prevention measure not guaranteed to work. So the authors have to monitor what is going on in the system and look for intrusion using Intrusion Detection System (IDS). In this IDS architecture multilayer specification based detection engine is used.
