End-to-End Delay Guaranteed Proportional Fair Scheduling for Wireless Networks.

In this letter, we propose a scheme for the guaranteed end-to-end delay with the proportional fair scheduling in wireless networks. With the newly introduced delay parameter, we adjust the queue length of each link. Specifically, we formulate a new optimization problem which guarantees the average end-to-end delay of each flow in wireless networks. Through simulation, we show that network throughput is improved while guaranteeing the average end-to-end delay compared to the existing results.
