Performance of opportunistic scheduling schemes for MIMO-OFDM wireless LANs

Abstract

In this paper, we propose and investigate scheduling algorithms for multiple-input multiple-output (MIMO) wireless local area networks (WLANs) based on orthogonal frequency division multiplexing (OFDM). We propose two new scheduling approaches which combines the channel states with queue states. The obtained results show that the proposed schemes outperform well known schemes such as proportional fair (PF) and shortest remaining processing time (SRPT) in terms of throughput and fairness.
