Routing Metrics and Protocols for Wireless Mesh Networks.

Wireless mesh networks (WMNs) are low-cost access networks built on cooperative routing over a backbone composed of stationary wireless routers. WMNs must deal with the highly unstable wireless medium. Thus, routing metrics and protocols are evolving by design- ing algorithms that consider link quality to choose the best routes. In this work, we analyze the state of the art in WMN metrics and propose taxonomy for WMN routing protocols. Performance measurements of a wireless mesh network deployed using various routing metrics are presented and corroborate our analysis.
