一种基于MQTT协议的物联网通信网关
|
摘要
当前物联网中数据的增长大大超过了网络带宽的增速,这对物联网通信提出了巨大挑战;而通信协议又是通信中的关键问题。论述了物联网对通信协议的要求,并认为MQTT协议符合了物联网通信的要求。在此基础上介绍了自主开发的基于MQTT协议并具有边缘计算功能的一种物联网通信网关,最后介绍了这个网关在智慧路灯案例中的应用。
At present,the growth of data in the Internet of Things has greatly exceeded the growth of network bandwidth,which brings a great challenge to the communication between the Internet of Things. And communication protocol is the key problem. This paper discusses the requirements for communication protocols of the Internet of Things( iot)and admits that the MQTT protocol meets the requirements for the iot communication. On this basis,this paper introduces a kind of communication gateway for the Internet of Things which is based on MQTT protocol and has edge computing function,and finally introduces the application of this gateway in the system of the smart street lamp.
