摘要:
该文比较了采用不同预约方式的宽带GEO卫星网络混合式按需 /自由分配协议,提出了采用混合式轮询 /捎带预约方式的CFDAMA- RPR协议。采用IFP信源进行计算机仿真,对CFDAMA- RPR、CFDAMA -RR(采用轮询预约方式 )和CFDAMA PB(采用捎带预约方式 )协议的时延性能进行了比较。仿真结果说明,CFDAMA- RPR协议具有更好的时延 /吞吐量性能。
Abstract:
This paper exam ines the relat ive performances of the Combined Free /Demand AssignmentMu ltiple Access (CFDAMA) pro toco lw ith d ifferent term inal request strateg ies. A new sate llitemultiple access scheme employ ing combined Round Rob in /Piggybacking Request strategy ( CFDAMA-RPR ) is proposed, which is compared w ith CFDAMA-RR ( employ ing Round Robin request strategy) and CFDAMA-PB ( employ ing Piggy- Backing request strategy). The delay performances betw een CFDAMA-RPR, CFDAMA-RR and CFDAMA-PB scheme were compared by computer smi ulation. Smi ulations were carried out by Interrupted F luid Process ( IFP) traffic. The results demonstrate that compared w ith CFDAMA-PB and CFDAMA-RR protoco,l CFDAMA- RPR scheme can offer better delay / throughput performance of the satellite channel.
