Abstract

Wireless LANs are very useful as disaster information networks because of their mobility, portability and easy installation. However, in the actual disaster case, electric power line is also damaged and those wireless LANs cannot be functioned. In this paper, we introduce a power saving cognitive wireless LANs for disaster use with combination of solar panel, wind turbine and battery, so that, the autonomous wireless network can be established and provide normal network functionality even through the other wired electric power and network are seriously damaged. Furthermore, by combining with multiple LANs with different transmission characteristics and selectively switching those, suitable communication environment can be provided even though the communication environment has been changed. Using combination of fixed and mobile cognitive networks, a large disaster communication network is organized. In this paper, we designed a wireless mobile network with currently available different wireless LANs and constructed a prototype system to evaluate the functional and performance.

面向灾难信息的节能认知无线局域网

无线局域网具有移动性、便携性和易于安装的特点，是灾害信息网络的重要组成部分。但是，在实际灾难情况下，电线也会被损坏，无线局域网无法正常工作。本文介绍了一种由太阳能电池板、风力涡轮机和电池组成的节电认知型灾害用无线局域网，在其他有线电力和网络严重损坏的情况下，也能建立自主无线网络，提供正常的网络功能。此外，通过将多个传输特性不同的局域网组合在一起，并对其进行选择性切换，即使通信环境发生了变化，也可以提供合适的通信环境。将固定认知网络与移动认知网络相结合，构建大型灾害通信网络。本文利用现有的各种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来评估其功能和性能。
