The Study of IOT Technology Based on Cloud Computing

This paper studied the cutting-edge technology of Internet of Things (IOT) based on cloud computing. The basic ideas and methods of the combination of cloud computing and the IOT are described is this paper. By combining the cloud computing and the IOT, we can design the function modules of intelligent water resources management system. To describe the reasonableness of the combination of cloud computing and the IOT, the problems about the development of this technology are summarized, and ideas to solve security problems are developed. To ensure the efficiency of cloud computing, clustering algorithms in transport layer has been introduced, which can reduce the loss of data. We classified the data by different security levels in application layer and made the different degrees of protection with different data. Considering three-layer model of the database structures, a ploy of permissions allocation is designed. In this ploy, every allocation of permission needs a complete authentication, which can avoid the security issues caused by unauthorized us- ers gaining unauthorized privileges in the traditional system. Besides, the support of the secondary development is essen- tially demanded in the development of IOT technology, and classifying the things in the IOT can make the users design it to meet this demand by themselves.
