Research And Implementation Of IOT Data Distribution System Based On Web Service

In recent years, Internet of Things(IOT) has gained rapid development in thewhole world,and has formed a networking services industry preliminarily. However,due to the perception of heterogeneous networking equipment, strong isomerism ofindustrial application platform and industry data, it results in fragmentation, poorscalability status of IOT networking applications.And it has brought great difficultiesto the design and development of IOT applications.For the background and problems above, this paper proposes a solution that theweb service will be used in IOT data distribution system. First, we study relatedtechnologies of IOT and web services, analyzes the advantages of web services,pointed out the feasibility of using web services in data distribution system of IOT.Secondly, design and implement a data distribution networking system based on webservices, the various functions of the system are abstract as web services, open to theoutside, using a web service as a unified interface, shielding the underlying heteroge-neity, using web services as communication method to complete message exchangewithin the system, and the interface of each module in the system has been designed.For a variety of IOT industry application data, we designed a new coding scheme andunified messaging message format to solve the heterogeneous applications and datanetworking strong issue. Service delivery system also supports a variety of applicati-ons, there is no need to deploy a system for each new application development; whileservice delivery system supports hot deployment of new applications, that is, whenadding new industry application server in the system, it will not affect the existingservices working. Then, the paper optimize the performance of service delivery syst-em from SOAP messages and database tables, giving two aspects which areoptimized proposed template-based SOAP message serialization and based ondatabase tables Hash tables of two optimization program. Give a detailed design andimplementation of the two aspects. And then, We test the functional performance ofthe system, the test results show that the system is accurate real-time data on theindustry distribution for industrial applications and can be thermal expansion. By testing the performance of the system and analyzing the performance indicators, weverify the upgrade optimized system performance. Finally, this paper user the systemin the base station battery monitoring platform IOT application scenarios, and showthe relevant part of its functionality.
