摘要
运用网络仿真软件OPNET Modeler10.5作为开发环境,建立了临近空间通信网模型,设计了媒体接入控制(MAC)层的时分多址(TDMA)接入协议,实现了各个地面站对临近空间物理链路资源的有效共享。利用排队理论推导了该协议下的平均网络时延计算公式。收集的仿真结果表明,理论分析能够较准确地估计平均网络时延。
A network model for the near space communication network is established by the means of OPNET Modelerl0.5 as a development environment, and a medium access control (MAC) protocol based on TDMA(Time Division Multiple Access) is designed,leading to the channel resource being shared efficiently. A formula for the average end to end ( ETE ) delay of the network is delivered according to the queue theory. Simulation results show the theoretic analysis can accurately estimate the average ETE delay of the network.
