RFID与WSN在物联网下协同机制的分析

摘要

在物联网的概念提出之前,射频识别(radio frequency identification,RFID)和无线传感器网络(wireless sensor network,WSN)均沿着各自的技术路线发展,它们之间的兼容性问题尚未被考虑.而在物联网中,这两种技术需不断地进行融合,研究它们在物联网中的工作机制和协作方式将具有十分重要的意义.通过对相关应用中RFID与WSN协作机制进行深入分析,将RFID与WSN在物联网下的协作分为四种融合方式,并对这四种融合方式的设计原理与工作过程进行了分析与探讨,最后指出了RFID与WSN协同工作机制目前需要解决的关键问题.%RFID technology and WSN were evolved respectively according to their technical features before the concept of Internet of things was proposed, and not concerned the compatibility between them. As the two technologies integrated continuously in Internet of things, it became a great significant work to research on the working mechanism and collaborative ways of RFID and WSN. Through deep analysis for the collaborative mechanism of the two technologies appeared in recent relevant applications, classified four forms of integration methods between RFID and WSN, dissected and investigated the designing principles and working process of the four forms of integration methods, and pointed out some key issues of the collaborative mechanism between RFID and WSN in Internet of things.
