Research, Design And Implementation Of Data Platform Based On Web Of Things

In recent years, Internet of Things and ubiquitous network developed rapidly and had a lot of achievements which has been widespread concerned in the community and academia. But there are still many problems exist behind the prosperity. Like there is no uniform standard, and each system is highly independent and remains closed between each other, it is difficult to share resources and data, etc. These problems limit the development of ubiquitous network towards a more open and flexible network. Therefore, ubiquitous network based on Web technology is proposed. Using Web technology to build ubiquitous network business environment, to take advantage of Web technology such as high degree of standardization and low threshold to achieve, to realize a more open, flexible and shared network.This paper studies ubiquitous network based on Web technology, mainly focuses on the design and implementation of data platform. First, characteristics of data in ubiquitous network is analyzed and data is classified. Then, based on the analysis and classification, the key points and challenges of data platform is summarized, to make the design requirements clear. Next, considering functional requirements, design principles and performance requirements, design of data platform for ubiquitous network based on Web is proposed. It mainly focuses on resource identifier and addressing, resource description, resource management, data storage and other issues. Finally, the paper introduces the technical implementation of data platform and test and validation work. According to research and implementation of WoT data platform, resource is managed in an uniformed manner, to enhance the accessibility, openness and ability to transfer data in ubiquitous network, making the network more open and flexible.
