A mobile Ad-hoc network (Mobile Ad-Hoc Network) is a self-created self-organized and self administering set of nodes connected via wireless links without the aid of any fixed infrastructure or centralized administrator. Security has become important to mobile ad hoc networks (Mobile Ad-Hoc Network). Due to its unique features such as limited power and limited bandwidth, open nature, lack of infrastructure and central management, node mobility and change of dynamic topology. It is mainly use for many intelligent missions and life-critical applications. However, the broadcast nature of inter-node communications and node mobility in Mobile Ad-Hoc Network make it very challenging to secure. Moreover, their constantly changing topology causes network node density and neighbor relationships to change dynamically. The prevention methods like authentication and cryptography techniques alone are not able to provide the security to these types of networks. Therefore, efficient intrusion detection must be deployed to facilitate the identification and isolation of attacks. The Intrusion Detection Systems utilizes are: (i) both anomaly and misuse detection schemes to identify attacks in Mobile Ad-Hoc Network and (ii) mobile agents (MAs) to augment each node’s intrusion-detection capability. In particular, each node is equipped with local IDS, and MAs will be dispatched periodically or on- demand to augment each node’s IDS. We present the design of these IDS and the overall network structure, as well as the methods for authenticating and dispatching MAs. This paper presents an intrusion detection system (IDS) for Mobile Ad-Hoc Network
