摘　　要：对战术adhoc子网业务量模型进行分析探讨,研究了自相似序列的几种产生算法。在多重ON/OFF源汇聚模型基础上设计了一种新的利用Opnet工具生成自相似业务的方法,该方法经检验能方便有效的得到自相似业务。最后对某连级战术子网进行仿真,得出结论:流量的自相似性对网络性能影响很大,这与传统流量模型的短相关性形成鲜明对比。研究成果对战术通信网流量的精确建模、资源的优化配置、网络性能的提高具有重要意义。Generation algorithm of network self-similar flow is analyzed and compared in this article.It raised an improved method of using opnet to generate self-similar stream.And the validity of this algorithm was demonstrated.Finally,it analyzed and summarized the influence of self-similarity of the communication stream to every performance index of tactical adhoc network after emulated measuring to the tactical subnet under heavy-tail ON/OFF self-similar model.The research has great significance for modeling accuracy of tactical network traffic,improvement of the network performance and optimization of the resources configuration.
