基于OPNET的室外布放WLAN的仿真研究﹡

摘要

无线网络具有使用方便、终端可移动、易于扩展等特点，随着校园内移动业务需求的增加以及无线网络的发展，在高校校园网内进行无线网络的部署必将成为一种趋势。这里首先介绍了WLAN的协议标准及组网方式，描述了高校 WLAN 部署中两种常见的场景，并给出了相应的 AP 部署方案。最后，针对室外布放建设方式的场景，使用OPNET软件进行了仿真分析，为校园网的WLAN实际部署提供了参考依据。%Wireless network is easy in use and expansion, and flexible in mobility for its terminals. Since the increasing demand for mobile service and the development of wireless network, WLAN would become the principal trend of campus network in the future. The protocol standard and the style networking mode of WLAN are described, then two common scenarios of WLAN deployment in universities are given, including the related AP deployment scheme, and finally the simulation with OPNET on outdoor arrangement based on OPNET is done, thus providing some reference for actual WLAN deployment in universities.
