基于MQTT协议的物联网通信系统的研究与实现

Research and Implementation of MQTT protocol on the Internet of Things communication system

MQTT是一个基于TCP/IP协议的简单、轻量型的发布/订阅消息协议,是新兴IoT(Internet of Things)领域的理想之选。IBM Bluemix Internet of Things(IoT)服务提供了简单且强大的功能将全球不同种类的设备和应用程序互联起来。在该IoT服务的基础上,研究了MQTT协议的结构和消息格式,设计了一款基于MQTT协议的移动通信客户端,实现了设备和移动端的数据传输,完成了在客户端的数据可视化。

MQTT, a simple and lightweight publish / subscribe messaging protocol based on TCP / IP protocol, is an ideal choice on the emerging IoT（Internet of Things） field. IBM Bluemix Internet of Things（IoT） service provides a simple and powerful function which can interconnect different types of devices and applications all over the world. On the basis of the IoT service,analyzed the structure of MQTT and the format of its message, designed a mobile communications client based MQTT protocol.Has finished data transmission between device and mobile client. Finally, realized the visualization on the mobile client.
