Abstract :
The purpose of our study is to guarantee the required throughput of high-priority (UDP) flows and to achieve the stable throughput for each flow in a wireless LAN in which both high-priority and low-priority (TCP) flows exist. The authors previously proposed a QoS control scheme called Receiving Opportunity Control in MAC Frame (ROC), in which an Access Point (AP) intentionally does not return an ACK for low-priority data frames. In this paper, we propose a novel QoS control scheme using Token Bucket Filter (TBF) based ROC, which achieves the above function. The TBF mechanism is known as a basic token based traffic control. The simulation results show the effectiveness of the proposed scheme.
