Mobile ad-hoc Network is a self organized wireless network which has a dynamic topology where nodes can be join or leave the network at anytime with large number of nodes. Due to its infrastructure less, dynamic topology and lack of centralization it is vulnerable to many security attacks. In this paper, we propose to detect the attack by using an Intrusion detection system that uses intuitionistic fuzzy logic which aims to detect distrust behavior of node and identify the attacks if it seems to be an attack based on given rules.
