Abstract
Downlink multiuser MIMO (DL MU-MIMO) has shown a great promise to enhance the performance of a wireless network by serving multiple users simultaneously. While researchers have focused on tackling the challenges involved in deploying these networks in the real world, little is known about their performance under the impact of traffic dynamics. In this paper, we evaluate the performance of DL MU-MIMO under the impact of traffic dynamics. Specifically we study how the system behaves under closed loop (FTP/TCP flows) and open loop traffic (UDP flows). We extend the network simulator ns 3 to include support functionalities for 802.11ac compliant DL MU-MIMO simulations. By performing extensive simulations, we find that 802.11ac MU-MIMO achieves extremely small queue lengths (
