摘要
通信信息并行传输效率是衡量移动通信网络系统性能的重要指标。为了提高移动网络信息通信速率,研究通信延迟对信息并行传输的影响。根据移动网络通信理论和IEEE802.11协议对移动网络信息并行通信过程进行分析,构建移动通信网络模型,得到串行延时、"数据包"的串行延时、路由延时、传播延时等参数,获取移动通信延迟与信息并行传输效率之间的约束关系,分析各个延迟参数对信息并行通信速率的影响。仿真结果表明,随着通信延迟的不断变化,信息并行传输速率也在发生变化,因此降低通信延迟能最大程度地提高信息并行传输速率。
The parallel transmission efficiency of communication information is an important index to measure the performance of mobile network system. In order to improve the information communication rate of mobile network, it is necessary to research the influence of communication delay on parallel information transmission. Based on the theory of mobile network communication and IEEE802.11 protocol, the process of parallel information communication of mobile network was analyzed. Moreover, the model of mobile communication network was constructed. Then, some parameters such as serial delay, serial delay of "data package", routing delay and propagation delay were obtained. After that, the constraint relation between mobile communication delay and information parallel transmission efficiency was obtained. Finally, the influence of each delay parameter on information parallel communication was analyzed. Simulation results show that, with the constant change of communication delay, the parallel transmission rate of information also changes. Accordingly, the reduction of communication delay can maximize the parallel transmission rate of information.
