Research And Application Of Service Management Of Open Platform For Internet Of Things

In today's world,the Internet of Things is regarded as the third wave of information technology,which will greatly promote the national economy,military and technology.Therefore,the country has started to promote the development of Internet of Things technology.The problem that has always existed in the Internet of Things is that the underlying devices are connected to the system to access the expressions in a unified manner.At the same time,data communication between different Internet of Things data center applications cannot be achieved,making the Internet of Things system open and scalable.There have always been shortcomings in nature,so the idea of an open platform for the Internet of Things has been proposed.Through an open platform to uniformly manage the underlying devices of the Internet of Things,according to the idea of service-oriented architecture,the functions of the interval devices are encapsulated into services,shielding the differences of the underlying devices.Structure,and provides a unified access method for upper-layer applications and users.But at the same time,the increase in services makes it difficult to manage services in the platform.Users face a large number of services with similar functions and need a suitable algorithm to screen these services.First,by analyzing the existing IoT platform,the functional requirements of the IoT open platform are summarized,and the overall architecture diagram of the IoT open platform is obtained.Secondly,in view of the existence of a large number of services with similar functions in the platform,which is difficult for users to select,the paper proposes a service selection algorithm based on the quality of service requirements and combining the user's willingness with the objective relationship between service quality attributes to help users choose a service that basically meets the users The service quality requirements and high-quality functional services fully consider the impact of subjective and objective factors on the comprehensive evaluation of functional services,and use the QWS data set to verify the feasibility and effectiveness of the modified algorithm.Finally,on the basis of theoretical research and needs analysis,a prototype system of an open platform for the Internet of Things was realized,and the basic functions of device management and service management were realized.At the same time,a service selection algorithm based on service quality was added to the system and carried out.The application.
