本文提出一种适于广播信道分布式局部网的分信道混合模式多址通信协议的概念(SC 3 MA)。并具体求出实现这种概念的SC 3 MA-Ⅱ协议的D-S关系在部分参数条件下的解析关系,对于未能求出这种解析关系的情况,已得结果可作为合适的上、下界。分析表明,SC3MA-Ⅱ协议的性能比其它协议有明显改善。 把SC 3 MA的概念与语音包业务的特点相结合,SC 3 MA-v/D协议在语音包时延有限而包丢失率最小的意义下是最优的。 本文所用的分析方法有一定新意,对处理类似问题有参考价值。
In this paper, we propose a concept of sub-channel hybrid mode multiple access communication protocol (SC 3 MA) for broadcast local area networks. We also obtain the analytic relation of D-S relation of SC 3 MA-Ⅱ protocol under some parameters conditions to achieve this concept. For the case of failing to obtain this analytic relationship, the obtained results can be regarded as the appropriate upper and lower bounds. Analysis shows that the performance of the SC3MA-Ⅱ protocol is significantly improved over other protocols. Combining the concept of SC 3 MA with the features of voice packet services, the SC 3 MA-v / D protocol is optimal in the sense that the delay of voice packets is limited while the packet loss rate is minimized. The analytical methods used in this paper have some new ideas, which have reference value for dealing with similar problems.
