A Survey on Intrusion Detection System in Mobile Ad-Hoc Networks

Mobile Ad-hoc Network (MANET) is an Emerging Technology. MANET is a great strong point to be applied in dangerous situations like battlefields and commercial applications such as construction, traffic surveillance. Each device in a MANET is without free to move in any direction and its changes the connections to other devices frequently. Mobile Ad-hoc network is faces several challenges such as Energy, Routing, Security, Quality of services, Memory and etc... But the flexibility in such atmosphere has the challenged in risk of security. The main Intrusion Detection is one of the possible ways in recognizing possible attacks before the system could be penetrate. The encryption and authentication solution are consider as the first line of protection, are no longer enough to protect MANETs. This paper defines several MANET security threats and focuses on MANET intrusion detection methods.
