适用于低成本物联网终端的消息通讯协议比较研究

摘要

在物联网系统中为了能够将终端和数据接入现有的企业级应用平台，普遍需要应用到消息中间件系统来处理分布式终端之间或其与云端的交互，为了针对不同应用场合选择合适的消息中间件来开发应用，文章分析了消息协议实现占用的空间，时间，交互模式，寻址方式和主要性能指标，筛选了几种适合在低成本终端中使用的消息协议，明确各协议适合的应用场合，并对它们进行了横向比较。%In order to make the terminal and data of the Internet of things connect with the enterprise application platform,a message oriented middleware system is usually used to deal with the interaction between a distributed terminal or a cloud.In order to develop and apply the appropriate message oriented middleware for different applications,this paper analyzes the space,time,interactive mode,addressing mode and main performance index of the message protocol.It selects several protocols of low cost terminals.It points out the suitable application of the protocol.A horizontal comparison is made to them.
