Routing in multi-radio, multi-hop wireless mesh networks
We present a new protocol for routing in multi-radio, multi-hop wireless networks. Our protocol, Multi-Radio Link-Quality Source Routing, is designed for wireless networks with stationary nodes, where each node is equipped with multiple independent radios. The goal of the protocol is to choose a high-throughput path between a source and a destination. Our protocol assigns weights to individual links based on the Expected Transmission Time (ETT) of a packet over the link. The ETT is a function of the loss rate and bandwidth of the link. The individual link weights are combined into a path metric called Weighted Cumulative ETT (WCETT) that explicitly accounts for the interference among links that use the same channel. The calculation of WCETT can be tuned to either maximize throughput of the given flow or to minimize its impact on other flows. We studied the performance of our protocol by implementing it in a wireless testbed consisting of 23 nodes, each equipped with two 802.11 wirel...
