Big Data Analytics in IoT with the Approach of Storage and Processing in Blockchain

Different organizations and service providers have defined, implemented, and recognized the IoT architecture in different ways. But the core architecture of IoT remains the same across all implementations and business models. The main architecture of the IoT system can be understood from a four-layer model: IoT devices and gateways, communication network, Cloud or server, and IoT application. Various methods have been presented for the way of information exchange, the amount of information exchanged, and the processing location of big data collected by the components of the Internet of Things or sensors. In this paper, while examining and analyzing the various methods of big data, such as cloud processing and fog processing, the corresponding pros and cons are reviewed. In a general way, by using the possibilities and potential of blockchain, it is tried to introduce a new method for analyzing big data on the Internet. Objects using the blockchain platform. In this method, in order to solve the problem of centralized storage of data generated in the IoT and to increase the fault tolerance and cost-effectiveness of the design, the method of storage in network sensors is considered, and to increase the reliability and reduce the volume of information transferred on the Internet network platform, processing It is proposed on the blockchain based on the requests received.
