本文提出了一种基于链路选择因子的高速无线个域网自适应时隙调度算法。在利用服务曲线对网络QoS需求进行建模的基础上,结合由链路质量获得的实时最优帧长,算法可以得出各个链路的选择因子。同时,选择因子的控制参数k能够决定调度算法的偏重点是链路质量还是业务QoS。仿真结果表明,该算法能在保证网络公平性的基础上有效地提高系统吞吐量。
This paper presents a high-speed wireless personal area network adaptive time-slot scheduling algorithm based on link selection factor. Based on the modeling of network QoS requirements by service curve and the optimal real-time frame length obtained from link quality, the algorithm can get the selection factor of each link. Meanwhile, the control parameter k of the selection factor can determine whether the emphasis of the scheduling algorithm is link quality or service QoS. Simulation results show that this algorithm can effectively improve system throughput on the basis of ensuring network fairness.
