摘要
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。
In this paper a link select-index based time slot scheduling algorithm for high speed wireless personal network （WPAN） is proposed, which schedules adaptively. Combined the quality of wireless link with the QoS which models ＂Service Curve＂ in the network, the algorithm obtains select-index of link that defined. Moreover, the parameter k used to control the algorithm will decide whether the quality of link or QoS of nodes will be weighed more. The simulation proves that the algorithm can improve the network throughput evidently and achieve a justified balance between the throughput and fairness.
