摘要
本文提出了一个适合微蜂窝移动通信的时分双工方式下的分组预约多址协议──F-PRMA（Frame-basedPacketReservationMultipleAccess）.利用马尔可夫过程理论为F-PRMA协议系统建立了三状态简化模型.应用Tasaka提出的平衡点分析方法（EPA）对该协议进行了性能分析，推导出了分组丢弃概率和系统吞吐率等重要性能参数的解析式.通过数值分析和系统仿真全面考察了允许概率P、帧长T、时隙数N以及话音分组最大允许时延Dmax等系统参数和协议变量对F-PRMA协议效率的影响.
A new Frame-based Packet Reservation Multiple Access(F-PRMA) protocol under time-division duplex is proposed for microcellular mobile networks. A three-state Markovian model of the F-PRMA system is developed based on Markov process theory. The performance of the protocol is analyzed by means of Equilibrium Point Analysis(EPA), which was presented by Tasaka, and the important measures such as packet dropping probability, system throughput are derived. The effects of the system parameters and protocol variables on the efficiency of the multiple access protocol are examined through numerical analysis and system simulation.
