摘　　要：提出了一种新的基于概率生成函数的方法,分析研究并给出了无线ATM(WATM)系统中平均缓冲器容量及平均分组延迟均的闭合解的表达式.所使用的模型不依赖于入队分组的状态,并允许入队是相关的,因此该模型可以适用于更广的范围.经过适当的调整,该方法对于具有缓冲器的单输出系统,基本上都可以适用.该研究拓展了WATM系统的研究方法,也为更广泛的具有缓冲器的系统研究提供了一种新的可能方法.A method based on probability generating function (pgf) was presented for analyzing buffer subsystem of wireless asynchronous transfer mode (WATM). A set of closed-form results were derived by using this method for the expectation of the buffer contents and packet delay of WATM systems. It is very clear and useful for analysis of the characteristics of buffer subsystems of WATM systems. Since this method is independent of states of the arrival process, it can be used for the buffer subsystems of WATM, and the more general systems with buffers. The simulation results show that this method is very effective and powerful.
