一种用于升空平台MAC层的调度方案

Scheduling scheme of MAC layer for stratospheric telecommunication platform

为满足升空平台的协议和不同业务流的属性需求,提出了一种完整的可以满足介质访问控制层服务质量和动态带宽分配的有效的调度方案,该调度方案不仅包括移动中心站对移动站的带宽分配,还包括移动站内上行业务的二级带宽分配架构。在仿真中通过对时隙发送特性、不同业务的延时特性,以及同种业务下不同算法的时延比较,验证了该调度方案的可行性。

To satisfy the protocol and requirements of different services flow of the stratospheric telecommunication platform, a scheduling scheme that could meet Medium Access Control （MAC） layer QoS and dynamic bandwidth allocation was proposed. The proposed scheduling scheme allocated up link and down link bandwidth not only to Mobile Station （MS） by Mobile Center Station （MCS） but also to all types of traffic in MS simultaneously and dynamically. At last, the simulation on the slot of different services flow, different delay characteristics of the traffic and different algorithms in the same services prove the feasibility of the scheme.
