认知无线电在矿井无线传感器网络系统中的应用
摘要
为了有效地实现矿井环境监测
将认知无线电(CR)技术和无线传感器网络(WSNs)技术相结合
提出了CR-WSNs新概念。分析了煤矿井下特殊的工作环境
介绍了适用于矿井的CR-WSNs监测系统结构、节点的硬件组成和CR-WSNs模块间的通信
给出了简单的性能测试方案。实际测试结果表明:CR-WSNs比普通WSNs具有更强的抗干扰性能。
Abstract
In order to realize environmental monitoring of coalmine effectively
a concept called cognitive radio-wireless sensor networks(CR-WSNs) is proposed combining CR technology with WSNs technology.Special working environment of the coalmine is analysed
and the structure of CR-WSNs system
the hardware of node and the communication between each module are introduced.A simple test program is given.The actual test result shows that the CR-WSNs has much better ability to resist interference than ordinary WSNs.
