Joint Stream Allocation and Scheduling for Single-User MIMO Communication in WMNs

Multiple-Input Multiple-Output (MIMO) technology has great potential for improving the throughput of Wireless Mesh Networks (WMNs). In this paper, the authors investigate the joint stream allocation and scheduling problem for single-user MIMO communication in WMNs with the objective of maximizing the demand satisfaction for a set of flows. The notion of Transmission Configuration (TC) is introduced and a heuristic algorithm is proposed to find a good subset of all possible TCs. Using these TCs, the joint stream allocation and scheduling problem is formulated as a Linear Programming (LP) and a Convex Program (CP) to obtain the maximum throughput and proportional fair solutions.
