摘要
近年来,利用商用大型网络仿真软件OPNET对无线网络进行仿真验证逐渐成为研究热点,很多资料对OPNET无线网络建模的基本方法进行了讨论,但甚少提及其中的仿真原理和细节。针对这些问题,对OPNET无线网络建模进行了精细的分析和研究,给出了定向天线的建模方法,以及在多个数据包同时到达收信机发生碰撞时管道阶段的处理方法,可以为OPNET无线网络仿真开发人员提供参考,尤其是对定向天线组网以及数据包冲突分析、丢包率计算等方面的研究提供开发依据。
Recently,the research on simulating and verifying the performance of wireless network by using large scale commercial simulation software,OPNET,becomes a hot scientific topic. Many materials present the general modeling method of wireless network based on it. However,the principles and details during the development process are rarely mentioned. A detailed research on modeling wireless network is performed via OPNET. The main contribution of the paper is to give the directional antenna modeling method and the pipeline handling process under the condition of multiple packets collision at the receiver,which could be a reference for the researchers developing wireless network simulation,especially in the domain of directional antenna network,packet collision analysis and packet loss ratio calculation.
