Relative Link Quality Assessment and Hybrid Routing Scheme for Wireless Mesh Networks
The authors present a link capacity estimation model and a hybrid routing scheme for wireless mesh networks which aims at improving throughput. The multi-source interference between links and frame capture behaviors of nodes are analyzed. Their model provides estimated values which can indicate the relative quality of wireless links. And they present a routing metric which combines multiple factors based on the estimated values. The proposed routing scheme which is independent of special routing protocols adopts different strategies for the traffic of accessing the Internet and the end-to-end traffic.
