On Routing of Multiple Concurrent User Requests in Multi-Radio Multi-Channel Wireless Mesh Networks

Abstract

Multiple-radio multiple-channel (MRMC) wireless mesh networks (WMNs) generally serve as wireless backbones for ubiquitous Internet access. These networks often face a challenge to satisfy multiple user traffic requests simultaneously between different source-destination pairs with different data transfer requirements. We construct analytical network models and formulate such multi-pair routing as a rigorous optimization problem. We design a cooperative routing and scheduling algorithm with channel assignment, in which, a primary path is built upon the selection of appropriate link patterns. The performance of the proposed algorithm is illustrated by simulation-based combinatorial experiments.
