摘要
传统的WLAN(Wireless LAN无线局域网)因为其单跳的网络特性造成了通讯瓶颈,这也使得其不能很好地满足地震应急救援通讯对效率、准确、安全等特性的要求。一种新型的无线网络形式WMN(Wireless Mesh Network无线网状网)的出现为构建下一代地震应急救援无线通讯系统提供了良好的网络基础。通过对传统地震应急救援无线平台和WMN的介绍,分析了构建新型地震应急救援无线通讯平台的技术指标和可行性,并且给出了平台搭建建议,最后对可能存在的问题以及应用前景进行了讨论。
With its characteristic of single-hop network,the conventional WLAN(Wireless LAN) makes low performance in network communication.So this architecture of wireless network cannot satisfy the requirements for efficiency,accuracy and security in earthquake emergency response and rescue mission.The WMN(Wireless Mesh Network) as the key technology of next generation provides a good network infrastructure of constructing new type wireless communication system of the mission.This paper analyzes the technology standard and feasibility of constructing new wireless communication platform of earthquake emergency response and rescue mission by the introduction of conventional wireless communication platform of the mission and some characteristics of WMN.At the same time,this paper also proposes a design draft of platform-construct.At last,the authors discuss the prospect and some problems of this new wireless communication platform.
