Being Opportunistic or Being Concurrent -- On Designing Channel Assignment Algorithms in Multi-Radio, Multi-Channel Wireless Mesh Networks

In this abstract, we have studied the problem of channel assignment in multi-radio, multi-channel wireless mesh networks, considering the support of opportunistic routing technique. First, we have formally modeled the channel assignment problem. Second, we have presented our multichannel opportunistic routing protocol. Third, we have shown the infeasibility of traditional channel assignment schemes, in the context of opportunistic routing. Finally, we have proposed a workload-aware channel assignment and routing algorithm, which can take advantages from both opportunistic throughput gain and multi-channel throughput gain.
