Bandwidth control for wireless access networks

Abstract

This paper provides a reference way to realize bandwidth control, a basic and important part of QoS, in WLAN. Using iptables and TC (traffic control) of Linux, AC (Access Control, the boundary node of a mini WLAN) controls all packets pass by. Packets can be dropped, be deferred or be delivered at once. Then, AC can control any user's bandwidth according to his IP address, MAC address, user name and so on. Besides that, it can set a user's priority with similar ways and a user with high priority will be served preferentially. At the end of this paper, we will talk about some possible improvement.
