In IEEE 802.11-based wireless mesh networks, routing is crucial in achieving high throughput in face of both interflow and intra-flow interference. Prior work focuses on finding the maximum available bandwidth path when a new flow enters the network. However, few have considered the effect of the new flow on the throughput of the existing flows. The authors propose a routing framework that uses the topology map of a mesh network with the carrier sense and interference relations and estimates the available bandwidth of a candidate path.
