On the End-to-End Flow Allocation and Channel Assignment in Multi-Channel Multi-Radio Wireless Mesh Networks With Partially Overlapped Channels
The performance of Wireless Mesh Networks (WMNs) can be improved significantly with the increase in number of channels and radios. Despite the availability of multiple channels in several of the current wireless standards, only a small fraction of them are non-overlapping and many channels are partially overlapped. In this paper, the authors formulate the joint channel assignment and flow allocation problem for multi-channel multi-radio WMNs as a Mixed Integer Linear Program (MILP). Unlike most of the previous studies, they consider the case when both non-overlapped and partially overlapped channels are being used.
