Nowadays, Mobile Ad Hoc Networks (MANETs) have become one of the most important networks in advanced technologies. However, MANETs are more vulnerable than wired and wireless networks to active and passive attacks. So, security and intrusion detection are very important in these networks. In this paper, we have presented a method of identifying IDS agent nodes in MANET. Whereas, IDS agent nodes due to monitoring activities in Intrusion Detection Systems (IDSs) need more battery energy than other nodes in the network. In the first step, our method uses a 3-layered key management framework in order to authenticate and then in the second step, nodes with higher battery power from among authorized nodes as IDS agent nodes are considered. Therefore, with this method, some authorized nodes contribute in monitoring activities and the network lifetime will be increased and also communication cost in the 3-layered key management framework is less than other frameworks, thus communication performance will be increased. doi:10.14456/WJST.2014.30
