Research And Development Of IOT Data Processing

The IOT is rapidly entering the living. It is an emerging strategic industries in China. A lot of companies and research institute are involved in research and development for IOT. It is a research focus in the field of information technology at present. The IOT framework is divided into perception layer, network layer, service layer and application layer, and the cloud computing as a new data processing layer, has been widespread in response to the industry. This industry is an emerging field it has many problems to be solved. Although the core technologies are controlled by foreign companies, the basic idea is open. Based on the idea from the open community and combined with the specific project, this article on the IOT and the cloud data processing are as the following:To solve the shortage of storage and energy anomaly in clustering in wireless sensor networks in the perceptual layer, we studied a progressive data transmission in sensor networks. The schedule algorithm is proposed. For a certain data transmission round, the number of nodes is decided by the memory size of the corresponding cluster-head. The cluster-head gathers the data transmitted by all small nodes and encodes them accordingly. The progressive data transmission with memory efficiency is thus formed. Theoretically and experimentally, our proposed method can further save energy consumption and reduce delay compared to DIMENSIONS. More importantly, it is memory-efficient.In the cloud services layer and application layer, in order to solve the problem of network congestion caused by intensive file upload, the file system IUFS has been proposed to support intensive file upload. As shown in Figure 2, it includes a core server, a data server, multiple area servers, and a large number of low-cost file servers. It ensures that users are automatically linked to the nearest or fastest file server. The metadata is automatically embedded into the file name; leading to decrease the amount of metadata; greatly improve the concurrent access ability of the core server and a easy implementing file synchronization algorithm is proposed. The system is stable and economically viable as showed by three years running.The intelligent form systems are designed for improving the development efficiency of the cloud computing applications..Net platform and JSP platform is designed and implemented based on AJAX and WEB services technology by the structure of the data table and field information such as regular expressions, the online and offline forms are generated, which includes multiple-records-edit form, single-record-edit form, intelligent-query form, intelligent-total form. The control components such as single-line text, multi-line text, select-option, and modal form may be used in the edit form, also the event handler function may be attached. The form is independent from the form builder, can be seamlessly integrated into application systems. The offline forms are generated dynamically at run time of the online form. Based on the above method, the cloud data management system is designed and implemented.The cloud security is mainly to solve the "confidentiality, integrity, authorization” in order to develop the cloud security system that its key is not stored in the CA, the remote call technology and remote dynamic compilation technology are used, by the user himself. The generated information generation contains RSA public key, private key, mold and related functional modules of digital certificates. This information is manually or automatically downloaded to the local.
