This paper analyses intrusion detection techniques and provides recommendations for preventing intrusions in peer-to-peer wireless networks. Peer-to-peer wireless networks are particularly vulnerable to attack due to their openness, dynamically changing topology, collaborative algorithms, lack of centralised monitoring, centralised control point and lack of clear protection. Intrusion detection techniques exist in wired networks but they are not applicable in wireless environment. The paper also presents a new intrusion defence method based on intrusion detection in peer-to-peer wireless networks.
