Abstract
Excellent scheduling algorithms can optimize allocation and improve utilization of wireless resources. To improve QoS of wireless networks, this paper presents a Dynamic Weight-Weight Fair Queuing (DW-WFQ) algorithm with differentiated service that is suited to characteristics of wireless networks based on WFQ algorithm. The proposed algorithm adaptively adjusts the weights of queues according to the dynamical measurement of link state. It can fully make use of limited wireless network resources and improve the overall throughput of network.The simulation experiment results using OPNET software tool demonstrate that the proposed algorithm can improve the network throughput and reduce the average end-to-end delay, compared with WFQ algorithm.
