IoT Protocols

CoAP “约束应用协议（CoAP）是一种软件协议，旨在用于非常简单的电子设备中，允许它们通过互联网进行交互式通信。它特别针对小型低功率传感器，开关，阀门和类似组件通过标准的互联网网络进行远程控制或监督.CoAP是一种应用层协议，旨在用于资源受限的互联网设备，如WSN节点。CoAP旨在轻松转换为HTTP以简化与Web的集成，同时满足多播支持，非常低的开销和简单性等特殊要求“ IETF Page	Description: "Constrained Application Protocol (CoAP) is a software protocol intended to be used in very simple electronics devices that allows them to communicate interactively over the Internet. It is particularly targeted for small low power sensors, switches, valves and similar components that need to be controlled or supervised remotely, through standard Internet networks.CoAP is an application layer protocol that is intended for use in resource-constrained internet devices, such as WSN nodes. CoAP is designed to easily translate to HTTP for simplified integration with the web, while also meeting specialized requirements such as multicast support, very low overhead, and simplicity"
RESTful HTTP “具象状态传输（REST）是分布式系统（如万维网）的一种软件体系结构，REST已经成为主要的Web API设计模型。”	Description: "Representational State Transfer (REST) is a style of software architecture for distributed systems such as the World Wide Web. REST has emerged as a predominant web API design model. "
MQTT “消息队列遥测传输（MQTT）是一种用于M2M通信的开放消息协议，可以将来自普及设备的消息形式的遥测式数据（沿高延迟或受限网络）传输到服务器或小型消息中间件。” Homepage (OASIS Page)	Description: "Message Queue Telemetry Transport (MQTT) is an open message protocol for M2M communications that enables the transfer of telemetry-style data in the form of messages from pervasive devices, along high latency or constrained networks, to a server or small message broker."
XMPP “可扩展消息和呈现协议（XMPP）是一种开放的实时通信技术，支持多种应用，包括即时消息，在线状态，多方聊天，语音和视频呼叫，协作，轻量级中间件，内容聚合，以及XML数据的广义路由。“ Foundation IETF WG	Description: "The Extensible Messaging and Presence Protocol (XMPP) is an open technology for real-time communication, which powers a wide range of applications including instant messaging, presence, multi-party chat, voice and video calls, collaboration, lightweight middleware, content syndication, and generalized routing of XML data."
