超宽带无线传感器网络综述

A Summarization of UWB Wireless Sensor Networks

集传感器技术、嵌入式计算技术、分布式信息处理技术以及无线通信技术为一体的无线传感器网络是一种全新的信息获取、处理和传输技术。笔者在简要介绍无线传感器网络体系结构和应用领域的基础上,分析了以超宽带无线电(ultrwidebandradio)为基本传输手段的新型超宽带无线传感器网络与传统正弦无线电传感器网络相比所具有的优越性。最后,针对超宽带无线传感器网络的特点提出了几点研究设想。

Wireless sensor nets which are integration of sensor techniques, nested computation techniques, distributed computation techniques and wireless communication techniques are absolutely new nets for information acquisition, processing and transmission. Firstly, the system structure and the application of wireless sensor nets are introduced, then the advantages of newly ultra wideband wireless sensor nets transferring information mainly depending on ultra wideband radio over the traditional sine wireless sensor nets are analyzed. In the end, some research assumptions aiming at the characteristics of wireless sensor nets are brought forward.
