: Intrusion detection system is one of the possible solutions to timely detect the intrusions and alarm for appropriate action. So far many intrusion detection systems have been proposed for ad-hoc networks, however due to the different characteristics, such intrusion detection systems cannot perform well in wireless mesh networks environment. In this paper, we propose a new framework of intrusion detection systems exclusively for wireless mesh networks. This paper will serve as a baseline guide for investigating intrusion detection systems for large scale multi-hop wireless broadband networks.
