物联网中WSN与网关的研究

A Survey on WSN and Gateway in the IoT

近年来,物联网(Io T)技术已经引起了很多关注,其能使不可识别的对象成为可识别的、互连的智能对象。物联网应用离不开互联网,事物信息需要上传到互联网,使得全球互联网用户可以共享事物信息。无线传感器网络(WSN),作为物联网的基本技术,可以收集、传输信息。而将信息传送到Internet需要网关作为桥接点。该文主要论述了物联网中无线传感器网络(WSN)和传统Internet网连接所用到的网关及其相关研究。

In recent years, the internet of things(IoTs) technology has attracted many attentions. The IoT can make the unidentifiable objects into identifiable, recognized, interconnected intelligent objects. The applications of the IoT can not be separated from the Internet. The things' information need to be uploaded to the Internet, which makes the users from the global share the information. As the basic technology of the IoT, Wireless Sensor Networks(WSN) can collect and transfer information. But a gateway is necessary for sending the information to the Internet as a bridge. The paper mainly studies gateways which are the connection used between WSN and the Internet in the IoT and gateways' related researches.
