摘要：A Mobile Adhoc Network is a collection of autonomous nodes or terminals which communicate with each other by forming a multihop radio network without the aid of any established infrastructure or centralized administration such as a base station. The Adhoc Network provides lack of secure boundaries. At present, the security issues on Mobile Adhoc Network have become one of the primary concerns. The MANET is more vulnerable to attacks as compared to wired networks due to distributed nature and lacks of infrastructure. Those vulnerabilities are nature of the MANET structure that cannot be removed easily. As a result, attacks with malicious intent have been and will be devised to exploit those vulnerabilities and to cripple the MANET Operation. Attacks prevention techniques such as a authentication and encryption, can be used as medium of defense for decreasing the possibilities of attacks. These techniques have a limitation on the effects of prevention techniques in practice 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 purpose, there exist a need of mechanism that “detect and response” these type of newer attacks i.e. “Intrusion and Detection”. Intrusion detection provide audit and monitoring capabilities that offer the local security to a node and help to perceive the specific trust level of other node. In addition to this ontology is a proven tool for this type of analysis. In this paper, specific ontology has been modeled which aims to explore and to classify current technique of Intrusion Detection System (IDS) aware MANET. To support these ideas, a discussion regarding attacks, IDS architecture and IDS in MANET are presented inclusively and then the comparison among several researches achievement will be evaluated based on these parameters.
