低轨卫星通信中基于公平性的信道借用策略
摘要
首先建立了LEO卫星移动模型和用户多媒体业务量模型
然后通过计算机仿真
分析了各种信道分配策略在LEO卫星多媒体通信中的性能
提出了信道借用切换策略(CBS)
仿真结果表明其能很好地满足LEO卫星多媒体业务的服务质量(QoS)
同时也提高了系统的信道利用率
最后讨论了3种不同信道借用策略的公平性和系统性能。
Abstract
A LEO satellite mobility model and user multimedia traffic model was first built
then a novel channel bor-rowing strategy(CBS)was proposed and its performance was evaluated and compared with several existing channel al-location schemes through computer simulation.Simulation results show this scheme can satisfy the QoS requirement of LEO satellite multimedia service very well
at the same time
keeping resource utilization high
finally discussed the fair-ness and system performance under three different channel borrowing strategies.
