Detection and Reaction to Malicious Node Behavior in Wireless Mesh Networks
In contrast to traditional infrastructure networking, Wireless Mesh Networks have a distinct multi-hop nature. This results in challenges related to a fair behavior with respect to traffic forwarding. There are numerous vulnerabilities to exploit in all layers of the communication stack. Methods for detecting malicious or misbehaving nodes have been proposed for MANETs. These proposals impose unnecessary overhead and do not make use of the available infrastructure of WMNs. The goal of the thesis is to analyze and evaluate proposed protocols for 802.11 mesh networks and study possible enhancements and reaction techniques. Also the applicability to other technologies like 802.15.1 and 802.15.4 is of concern.
