摘要：
MIMO links enable concurrent transmissions of multiple independent data streams between a pair of nodes, which can significantly improve network throughput. In this paper, we study the stream control and scheduling problems in multihop wireless networks with MIMO links. We present a constant factor approximation algorithm as well as an efficient heuristic algorithm for stream control. Moreover, we extend the results to incorporate TDMA-based scheduling and present effective heuristic algorithms to solve the joint Stream Control and Scheduling Problem (SCSP), whose efficiency is justified by simulation results.
