| 摘 要： | 提出了地面站采用预测预约算法的混合式按需／自由分配-预测预约（CFDAMA-PR）卫星媒体接入控制协议。CFDAMA-PR协议可采用预定预约时隙或轮询预约时隙发送预约请求。在文中，通过计算机仿真对预定时隙预约CFDAMA-PR、CFDAMA-PA与基本DAMA协议进行性能比较，同时还对轮询预约CFDAMA-PR和CFDAMA-RR协议进行了仿真性能比较，仿真中采用IFP突发信源，仿真结果说明CFDAMA-PR协议采用预测预约算法，实现了更好的时延／吞吐量性能。

| Abstract: | The novel satellite multiple access protocol called Combined Free/Demand Assignment Multiple Access-Predictive Request(CFDAMA-PR) is proposed in this paper.CFDAMA-PR can make slot reservation by pre-assigned request slots or round robin request slots.The delay performance between CFDAMA-PR with pre-assigned request,CFDAMA-PA and pure DAMA protocol is compared by computer simulation.Then,the delay performance between CFDAMA-PR with round robin request and CFDAMA-RR protocol is also compared by computer simulation.Simulations are performed with the Interrupted Fluid Process(IFP) traffic. Simulation results demonstrate that CFDAMA-PR achieves a better delay/throughput performance. |
