Evaluating And Comparison Of Intrusion In Mobile AD HOC Networks

In recent years, the use of mobile ad hoc network (MANETs) has been widespread in many applications.Due to its deployment nature, MANETs are more vulnerable to malicious attack. The absolute security in the mobile ad hoc network is very hard to achieve because of its fundamental characteristics, such as dynamic topology, open medium, absence of infrastructure, limited power and limited bandwidth. The Prevention methods like authentication and cryptography techniques alone are not able to provide the security to these types of networks. However, these techniques have a limitation on the effects of prevention techniques in general and they are designed for a set of known attacks. They are unlikely to prevent newer attacks that are designed for circumventing the existing security measures. For this reason, there is a need of second mechanism to “detect and response” these newer attacks. Therefore, efficient intrusion detection must be deployed to facilitate the identification and isolation of attacks. In this article we classify the architecture for IDS that have so far been introduced for MANETs, and then existing intrusion detection techniques in MANETs presented and compared. We then provide some directions for future researches.
