An efficient scheduling algorithm for QoS in wireless packet data transmission

In this paper, we proposed an efficient packet scheduling scheme, where the tradeoff of channel condition and QoS (quality of service) is factored according to the user traffic. It can be performed by adding the exponent term to the part of DRC (data rate control) which indicates the channel condition, in the proportional fair algorithm. With measuring the current level of supporting the QoS and controlling the DRC exponent, the proposed scheme can enhance the overall throughput without violating the QoS threshold.
