摘要
为了提高数据传输的有效性和可靠性,针对不同业务的不同QoS(Quality of Service)要求,提出了一种基于预测和优先级的IEEE 802.16时隙调度策略。根据不同业务的不同优先级,预留出时隙,优先将时隙分配给优先权高的业务使用,以满足不同业务的不同QoS需求;同时对SS发出请求和BS响应请求时间段到达的数据进行预测,进一步优化时隙调度策略,改善时延特性。仿真结果验证了其有效性。
In order to improve the efficiency and reliability of the data transmission and satisfy the different QoS （ Quality of Service） requirements. A kind of slot-scheduling mechanism is introduced which is based on prediction and priority in IEEE 802. 16 Mesh mode： According to different priority of different service, slots are reserved for high priority service to meet different QoS; at the same time it predict the data quantity coming between the time SS sending messages and the time BS granting messages, so that it can improve the scheduling mechanism, and improve the characteristic of delay.
