ABSTRACT
This chapter presents a different approach to tackling intruders in wireless mesh networks (WMN). The traditional approach of intruder detection and prevention suggests purging out intruders immediately after their detection. The chapter discusses other available literature, essential knowledge on wireless networks, intrusion detection and prevention, and status of intrusion-related works for WMNs. It describes a multi-hop acknowledgement-based algorithm to detect malicious nodes doing a selective forwarding attack. Owing to the structure of WMNs, it is possible to use this method. WMNs consist of mesh routers and mesh clients, where mesh routers form the backbone of the network that provides network access to both the mesh and conventional clients. If the intruders’ resources are used for the network and strong cryptographic mechanisms protect the network packets, intrusion tackling model can prove to be one of the best solutions to deal with WMN intrusion.
