MIMO link scheduling for interference suppression in dense wireless networks

This paper addresses the problem of fair scheduling of MIMO links in dense wireless network deployments where interference suppression is carried out via linear MIMO processing to optimize network performance. We formulate and solve an optimal MIMO link scheduling problem, where the goal is to maximize aggregate throughput while meeting a specified fairness criterion. Evaluations in a modified version of ns-3 show that our MIMO link scheduler more than doubles the performance of 802.11n, while achieving a fairness index of 90-95%.
