摘要:
随着卫星通信网络的发展,基于卫星通信网络实现手机、平板电脑等移动通信设备之间的通信成为研究的热点。由于其采用无线电波进行信号传输,且需要经过多个中继站进行信号的转
发和处理,导致存在网络延时大、丢包率高以及信道狭窄等问题。 针对文本信息在卫星通信网络下的分发过程存在效率低下、可靠性不高的问题,设计一种基于 MQTT(Message Queuing Telemetry Transport) 协议的轻量化文本信息分发技术。 该技术使用 MQTT 协议作为消息传输协议,在文本信息分发前对 MQTT 协议进行主题设计、发布订阅机制设计、设备连接设计以

表明:相较于传统的基于 JSON 数据的文本信息分发技术,该技术在提高文本信息分发效率的同时,可确保信息分发的安全性、完整性和稳定性。
Abstract:
With the development of satellite communication network,the communication between mobile devices such as mobile phonesand tablet computers based on satellite communication network has become a research hotspot. Because it uses radio waves for signaltransmission and needs to pass through multiple relay stations for signal forwarding and processing,it?
has problems such as large networkdelay,high packet loss rate and narrow channel. Aiming at the problems of low efficiency and low reliability of text informationdistribution in satellite communication network,a lightweight text information distribution technology based on MQTT ( Message QueuingTelemetry Transport) protocol is designed. In this technology,MQTT protocol is used as the message transmission protocol. Before textinformation is distributed,subject design,publishing and subscription mechanism design,device connection design?
and device heartbeatdesign of MQTT protocol are carried out to ensure connectivity between devices. During text information distribution,data verificationand encryption algorithms, lightweight text information processing methods, and offline message storage mechanisms are designed toensure the security and reliability of text information distribution. Experimental results show that compared with traditional textinformation distribution technology based on JSON data, the proposed technology can improve the efficiency of text informationdistribution and ensure the security,integrity and stability of information distribution.
