Fair Wireless Link Resource Management in Cellular Packet Switched Networks Steve Wilbur and Minseok Kang Mobile computers require varied characteristics from their wireless link to a fixed network. Conferencing applications require bandwidth guarantees in order to send and receive continual audio and video information. This work is examining ways in which several users with a mixture of these requirements can be given fair access to a shared cellular link. A system is proposed which separates data flows into three categories. Absolute flows are guaranteed a minimum bit rate service as long as simultaneous absolute guarantees do not exceed the total bandwidth available.
Weighted flows receive a rate-based proportion of bandwidth left over from absolute flows.
Best-effort flows make use of any remaining bandwidth. While the scheduling system installed at a base station can provide a guaranteed bandwidth to a downlink stream, the uplink traffic can not be guaranteed by the system due to the channel contention among the mobile stations. To solve the problem, a uplink sharing scheme will be developed to control contentions. It uses tokens to distribute channels to downlink streams and works with the scheduling system.
