Abstract
Due to the recent increased interest in wireless mesh networks
(WMN), their security challenges have become of paramount
importance. An important security mechanism
for WMN, intrusion detection, has received considerable attention
from the research community. Recent results show
that traditional monitoring mechanisms are not applicable
to real-worldWMNdue to their constrained resources (memory
and processing power), which result in high false negative
rates since only few IDS functions can be activated
on monitoring nodes. Cooperative solutions, on the other
hand, have high communication overhead and detection delay
when traffic is high. A practical traffic-aware IDS solution
was recently proposed for resource-constrained WMN,
however, traffic-awareness might not be feasible for some
WMN applications. This paper proposes a traffic-agnostic
IDS solution that uses a link-coverage approach to monitor
both local and backbone WMN traffic. Using real-world experiments
and extensive simulations we show our proposed
IDS solutions outperform traffic-aware IDS solutions while
requiring lower computation and communication overhead.
