A Testbed Implementation of Monitoring Assisted Local Route Recovery Scheme for Wireless Mesh Networks

Free registration required

Executive Summary

In this paper, the authors present experimental results from testbed implementation of a simple monitoring assisted local route recovery scheme for Wireless Mesh Networks (WMN). The scheme exploits the broadcast nature of wireless transmissions at special routers with added monitoring functionalities. These routers passively listen to the transmissions in the neighborhood and compare the forwarding behavior against pre-specified thresholds. If forwarded traffic exceeds the threshold, as a result of a malfunction, e.g., Denial-of-Service (DoS) attack or node failure, these routers try to isolate the node causing the problem by routing the traffic around it.
