Research And Implementation Of Messaging Protocols Of Io T-enabled Device

With the rapid development of Internet of Things,the research of messaging protocol has been paid more and more attention.Messaging protocol system is the core of Io T-enabled device;it is the focus of the research.There are a wide variety of messaging protocols currently,no one protocol can be suitable for all domains in Internet of Thing and dominate everything.The research of flexible support for a variety of different protocols of messaging protocol has the great value on both theoretical research and practical application.This thesis focuses on the research and implementation of the messaging protocols of Io T-enabled device based on Linux,and designs the messaging protocol system as independent messaging protocol middleware,that is,the complete messaging protocol solution.First,a multi-protocol,high-scalable framework is designed and implemented for the system.Based on the framework,the ONVIF protocol and the GB / T 28181 protocol for the network video surveillance domain of the Internet of Things are realized for the Io T-enabled device that with camera.Then,for the smart vehicle domain,combined with the characteristics of the cellular network,a lightweight private protocol is designed and implemented to support cloud storage,remote monitoring,transaction alarm and remote wakeup.Finally,the design and implementation of the system is verified and analyzed in the application of engineering practice,completed the theoretical research results of engineering applications.
