A Throughput Request Satisfaction Method for Concurrently Communicating Multiple Hosts in Wireless Local Area Network.

Nowadays, the has been widely used for Internet access services around the world. Then, the or in meeting the can appear among concurrently communicating hosts with the same , which should be solved by sacrificing advantageous hosts. Previously, we studied the by adopting at the AP. However, it suffers from slow convergence and may not satisfy different throughput requests among hosts. In this paper, we propose a for providing fair or different throughput requests when multiple hosts are concurrently communicating with a single AP. To meet the throughput request, the method (1) measures the and for each host, (2) calculates the from them, (3) derives the to achieve the given , and (4) controls the traffic by applying at the AP. For evaluations, we implemented the proposal in the WLAN testbed system with one AP and up to five hosts, and conducted extensive experiments in five scenarios with different throughput requests. The results confirmed the effectiveness of our proposal.
