Research And Interfaces Design Of Web-Based Ubiquitous Network Middleware

With the development of information technology, the concept of ubiquitous networks attracts more and more people’s attention. From large scale sensor networks consist of thousands of sensors to small networks of personal sensor terminals, they all provide a wealth of evidence for ubiquitous networks application. A number of data sources and applications of many different functions create a good environment for ubiquitous networks, but this also brings a lot of problems. How a variety of heterogeneous data sources access into ubiquitous networks and how the resources and service capabilities provided by the network open through a unified approach are important issues need to be resolved in the ubiquitous networks development process.Through the research for the ubiquitous networks middleware, the essay designs and implements a series of related interfaces. According to the ubiquitous networks business environment analysis, the article gives a detailed Web of Things architecture, to tease out some common access modes. At the same time, the functions of each part of WoT system also be analyzed. Combined with the designed interface messages and interaction processes, a prototype of middleware interfaces has been implemented based on Web technology. In addition, the article checks the function and evaluates the performance of implemented prototype through test tools and methods. And the suggestion of data traffic, concurrent support and data caches, etc. are given for follow-up optimization tips.Through the Web-based ubiquitous network middleware research and interface design, the data can be transmitted and opened in a uniform way. The effectiveness of data transmission, storage and open have been improved, and the open capability of the services are also has been enhanced.
