摘要

为了提高CFDAMA (combined free/demand assignment multiple access)协议在ON-OFF通信量下的时延性能，提出了一种新的卫星多址方案CFDAMA- cfa，该方案采用组合加权/轮询自由分配策略。通过计算机仿真比较了CFDAMA-CFA和CFDAMA-PA的延迟性能。采用IPP(中断泊松过程)和IFP(中断流体过程)流量进行了模拟。仿真结果表明，与CFDAMA-PA协议相比，CFDAMA-CFA协议实现了更低的延迟，并且满足了更低的延迟约束

Performance of CFDAMA-CFA multiple access protocol via satellite

In order to improve the delay performance of CFDAMA (combined free/demand assignment multiple access) protocol with ON-OFF traffic, a novel satellite multiple access scheme called CFDAMA-CFA, employing the combined weighted/round robin free assignment strategy, is proposed in the paper. The delay performances between CFDAMA-CFA and CFDAMA-PA were compared by computer simulation. Simulations were carried out with IPP (interrupted Poisson process) and IFP (interrupted fluid process) traffic. Simulation results demonstrate that compared to CFDAMA-PA protocol, CFDAMA-CFA achieves a lower delay and meets a much lower delay constraint
