基于MQTT的物联网系统 文件传输方法的实现
Implementation of file transfer method for Internet of things system based on MQTT
摘要
Abstract
Aiming at the requirement of file transfer between equipment and equipment in In-ternet of things system ,combined with the application characteristics of MQTT protocol in Internet of things system ,a file transfer scheme based on MQTT protocol is proposed ,the confirmation reply ,timeout retransmission mechanism is added on the basis of file split transmission t to solves the problem during the MQTT protocol in fulfilling the file transfer that has limited resource resources ,the channel takes a long time in the transmission process and packet ,to achieve the file upload and dow nload functions .Finally ,the function and relia-bility of the file transfer are tested by setting up the hardware platform .The experimental re-sults show that the file transfer scheme is reliable ,and it is suitable for the remote file trans-fer between the devices in the Internet of things system .关键词
