摘要
通过对流星余迹信道观测数据的分析,恢复出信道分布规律,建立流星余迹信道模型。将信道模型应用到网络仿真中,结合流星余迹网络结构模型、节点模型和通信协议模型,对多种运行参数进行仿真分析,验证采用退N协议的星型网络在实际数据驱动下的网络性能,得到最小发包时延和最大网络吞吐量的条件,为流星余迹通信系统的技术突破和设备研制提供可靠依据。
Based on the analysis of the measured data of the meteor channel,the channel distribution pattern is obtained and channel model is constructed.The channel model is applied into network simulation combined with the network models,node models and communication protocol models.By analysis of simulation results,the performance of adopting the ARQ protocol is verified and the condition of the minimum delay and the maximum throughput is obtained.The results provide a reliable basis for technology break-through of meteor burst communication system and development of equipment.
