摘要：AbstractMobile Ad hoc Network consists of some nodes that are stand randomly in operational environment. Because nodes are without any predefined infrastructure and mobility then that are susceptible for intrusion and attack. Securing is an important field in this type of network. In this paper we aim to representing concept of intrusion detection and then survey some of major intrusion detection approach in MANET and aim to comparing in some important field such as: use methods, type of attacks addressed, overhead, and architecture.
