Abstract :
Multiple-Input Multiple-Output (MIMO) technology has great potential for improving the throughput of Wireless mesh networks (WMNs). In this paper, we investigate joint rate allocation, routing, and stream control scheduling problem in MIMO-based WMNs, where multiple antennas are exploited to increase the capacity via interference suppression (IS) and/or spatial multiplexing (SM). The notion of transmission configuration (TC) is considered and a heuristic algorithm is proposed to find a good subset of all possible TCs. Using these TCs, we present convex programming (CP) formulations to find a proportional fair rate allocation solution. The simulation results demonstrate that performance of the proposed heuristic algorithm is very near to the optimal solution. The computational complexity of the proposed heuristic algorithm is substantially less compared to the optimal solution.
