Survey on Load-Balancing Methods in 802.11 Infrastructure Mode Wireless Networks for Improving Quality of Service

摘要: Traffic load in any 802.11 infrastructure mode network is typically distributed unevenly between access points (APs), creating hotspots. This due to the inherent nature of wireless area networks (WLANs), where stations are free associate known AP they desire, and lack control by APs themselves. imbalance creates a condition affected suffer traffic congestion while others underutilized, leading experiencing lower throughput, longer latency, operating below potential capacity. To alleviate this problem, some form balancing required redistribute work among other available network. article presents survey various works done performing an will cover common methods including admission control, association management, cell breathing, control. Updates IEEE standards also presented that support load-balancing efforts. Finally, software-defined investigated determine extent integration managing WLANs. Trends research uncovered indicate how introduction new influences amount research.
