Fusion Application of Big Data and Cloud Computing In the Internet of Things

Abstract

The Internet of Things can be simply understood as the mode of connecting things in the Internet environment. It is mainly the organic combination of computer, Internet technology and other information technology means. At the same time, the organic combination of the Internet of Things, big data, cloud computing and other advanced information thinking and computing methods is the direction of the future smart city construction. In the experiment, due to the characteristics of real-time and massive data of the Internet of Things, the fusion processing of big data cannot be carried out well. Based on the Internet of Things technology, cloud computing technology and fusion algorithm are selected for research. Experimental data show that the number of four types of nodes is set as 30, and the system has 100 nodes in total, and the length of one rotation of the system is 50s. The ordinary Leacha algorithm is used first, and then the improved Leach algorithm is used in the same environment. The experimental results show that there are four different types of nodes in the monitoring environment obtained by the test, and the initial data transmission rates of each node are 60, 90, 110 and 80 respectively. Therefore, the adjusted and improved LEACH algorithm can allocate the required data transmission time according to the different failure levels of the data. If the aging level is higher, the data transmission time of node data will be relatively longer. The improved strategy is in line with the characteristics of the Internet of Things and has the feasibility to complete the experiment.

Analysis of Internet of Things encrypted data based on cloud computing platform

“…And this trusted third party is willing to help all participants perform computing tasks. In the actual operation process, due to the complicated calculation process of re-encryption, the idea of revocable encryption is adopted, specifically, reEncrypt will be reasonably called to update the ciphertext only when the data is accessed [8][9] . All participants send their private inputs to the trusted third party through a completely secure channel, and the trusted third party then calculates the objective function and delivers the specified output to each participant.…”

Application of cloud computing in the construction of power network security immune system

“…Cloud computing resource server module is generated based on asymmetric key. We have already introduced the encryption method of asymmetric key [9][10]. The encryption and decryption keys of this encryption method are not the same.…”

The application of Internet of things and Oracle database in the research of intelligent data management system

“…Basic operations mainly include basic transaction operations such as adding, deleting, updating, and querying [28] performed by the user in the foreground. This module is responsible for receiving and parsing user requests from the foreground, and calling the corresponding module to access the database to obtain information, or modify the database content.…”
