The Research And Implementation Of Iot Service Mid Ware Based On Cloud Platform

With cloud computing technology and micro-service architecture widely recognized in the field of IT.the development of the Internet of Things ushered in a new wave of upsurge.A maj or difficulty in solving the problem of the Internet of Things is how to make different underlying devices more friendly and convenient to access the Internet and have a more unified way of expression.Previous emancipation schemes were limited by technical vision and other reasons.In this paper,a solution of Internet of Things service middleware is proposed,which combines with the leading technology in the industry,and the problems caused by the solution are studied and solved in depth.Firstly,the paper summarizes the functional characteristics of an Internet of Things system,and on this basis,summarizes and abstracts them,and finally obtains a set of functional architecture of Internet of Things service middleware.Secondly,the core of Internet of Things service middleware is to the capabilities of devices into entity services for unified management and invocation.this paper proposes a service discovery algorithm based on regression model,which makes full use of the historical data of service invocation.Finally,the entity services under the Internet of Things service middleware have the characteristics of homogeneity.In the process of service invocation,the problem of filtering and locating a large number of identical devices under the same service will arise.and an index-based algorithm model is proposed for filtering operation of entity equipment.In order to validate the effectiveness of the service middleware of the Internet of Things(IOT)and its algorithm model,the results of this paper have been applied to two enterprise cooperation projects,Through two project applications,the effectiveness of the work of this paper has been fully verified.
