摘要

本文介绍了一种将不同的无线局域网与移动网络相结合的灾害通信网移动网络。现有的IEEE802.11b、g、j、n、IEEE802.16、蜂窝网络等无线局域网与移动路由器结合,装载在汽车上,构建认知无线局域网节点。利用多个移动网络节点,组织一个大型灾难通信网络。节点之间的通信路径有多条链路,根据距离、功率和传输频率选择其中合适的链路。通过对这些节点的多跳,即使某些信息基础设施遭到破坏,用户也可以与其他用户进行通信并发送/接收灾难信息。本文利用现有的无线局域网设计了一个无线移动网络,并构建了一个原型系统,对其功能和性能进行了评估。

Disaster Information Network by Cognitive Radio LANs
In this paper, we introduce a mobile network for disaster communication network by combination of different wireless LANs and mobile network. Currently available wireless LANs such as IEEE802.11b,g,j,n, IEEE802.16, cellular network are combined with a mobile router and loaded on a car to build a cognitive radio LAN node. Using multiple mobile network nodes, a large disaster communication network is organized. A communication path between nodes has multiple links and the suitable links among them is selected based on the distance, power and transmission frequency. By multi-hopping those nodes, user can communicate with other user and send/receive disaster information even though some of information infrastructure are damaged. In this paper, we designed a wireless mobile network with currently available different wireless LANs and constructed a prototyped system to evaluate the functional and performance.
