Intrusion Detection in MANET using fuzzy logic

Mobile Ad hoc network (MANET) is a new paradigm in wireless revolution, which is a self-configured network of wireless mobile nodes. Due to proliferation of miniature yet powerful mobile computing devices, it is gaining acceptance and popularity. However, MANET is vulnerable to security attacks due to its inherent characteristics such as dynamic topology, lack of a centralized coordinator and open wireless channel. In this paper, we analyze some security attacks of MANET and we propose to identify the attack by using an Intrusion Detection System (IDS). The proposed IDS uses fuzzy logic to detect malicious behavior and identify the attacks.
