摘　　要：在深入研究视景仿真技术与OPNET网络仿真机制的基础上,利用视景技术模拟无线通信网络(WCN)中的通信节点运动、环境影响因素等,直观展示网络仿真结果中的非视觉物理量,可以为无线通信网络性能的研究带来新视角。首先介绍了一套具有以上特点的仿真系统的功能、软硬件结构等,考虑到分布式仿真系统(DSSS)的可移植性和扩展性,对系统做了精细的模块划分,然后探讨了具体实现上的几项关键技术,最后给出了仿真效果图。仿真结果表明利用本视景仿真系统能够帮助仿真人员对通信网络性能进行直观了解并做出具体评估,具有一定的现实指导意义。After the in-depth study of scene simulation and the mechanism of OPNET network simulation, the two techniques are used to simulate the communication nodes＇ movement, environmental factors affecting Wireless Communication Network （WCN） and so on. And then, some special visual effects are generated according to the corresponding data resulting from communication simulation, which brings forward a new visual angle for the research on WCN. In the document, the capabilities, hardware and software structure of Distributed Scene Simulation System （DSSS） based on WCN are explicated, and DSSS is divided into several delicate modules which have universal applicability and excellent expandability. In addition, some pivotal techniques are discussed. Finally, several pictures are presented to describe simulation effects. Those simulation results indicate that researchers can have further intuitive cognition of the WCN and exactly appraise it, and the DSSS has practical significance to some extent.
