Executive Summary

Wireless Mesh Networks (WMNs) are considered as cost effective, easily deployable and capable of extending Internet connectivity. However, one of the major challenges in deploying reliable WMNs is preventing their nodes from malicious attacks, which is of particular concern as attacks can severely degrade network performance. When a DoS attack is targeted over an entire communication path, it is called a path-based DoS attack. The authors study the performance impact of path-based DoS attacks by considering attack intensity, medium errors, physical diversity, collusion and hop count.
