Research on Lightweight Text Information Distribution Technology Based on MQTT Protocol
With the development of satellite communication network,the communication between mobile devices such as mobile phones and tablet computers based on satellite communication network has become a research hotspot.Because it uses radio waves for signal transmission and needs to pass through multiple relay stations for signal forwarding and processing,it has problems such as large network delay,high packet loss rate and narrow channel.Aiming at the problems of low efficiency and low reliability of text information distribution in satellite communication network,a lightweight text information distribution technology based on MQTT(Message Queuing Telemetry Transport)protocol is designed.In this technology,MQTT protocol is used as the message transmission protocol.Before text information is distributed,subject design,publishing and subscription mechanism design,device connection design and device heartbeat design of MQTT protocol are carried out to ensure connectivity between devices.During text information distribution,data verification and encryption algorithms,lightweight text information processing methods,and offline message storage mechanisms are designed to ensure the security and reliability of text information distribution.Experimental results show that compared with traditional text information distribution technology based on JSON data,the proposed technology can improve the efficiency of text information distribution and ensure the security,integrity and stability of information distribution.
