Message transmitting method and device in Internet of things

Abstract

The invention relates to a message transmitting method and device in the Internet of things. The method comprises the steps of receiving a message instruction transmitted through an MQTT (Message Queuing Telemetry Transport) protocol, wherein the message instruction comprises message sending end information, message performing end information, a time stamp and overtime information; detecting whether the message instruction is overtime or not according to the time stamp and the overtime time information in the message instruction; if the message instruction is overtime, detecting whether the current terminal is a message performing end or not according to the message performing end information in the message instruction; if the message instruction is overtime and the current terminal is the message performing end, giving up performing the message instruction and sending overtime prompt information to a message sending end according to the message sending end information; and if the message instruction is overtime and the current terminal is not the message performing end, interrupting transmission of the message instruction and sending the overtime prompt information to the message sending end according to the message sending end information. The certainty of the performing condition of the message instruction transmitted through the MQTT is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a message delivery method and device in the Internet of Things. Background technique [0002] With the rapid development of information technology, the Internet of Things has become an important part of the new generation of information technology. In the Internet of Things system, items are connected through the Internet, and messages can be exchanged and communicated between items through the Internet. [0003] In traditional IoT messaging, the MQTT (Message Queuing Telemetry Transport) communication protocol is mostly used. The MQTT protocol is an instant messaging protocol that uses a lightweight publish and subscribe message transmission mechanism. Compared with other communication protocols, the MQTT protocol is simpler and easier to use. It is especially suitable for low network bandwidth, high network delay, and unstable network communication. in a restricted ...
