Abstract
With the rapid development of the industrial Internet of Things and the comprehensive popularization of mobile intelligent devices, the construction of smart city and economic development of wireless network demand are increasingly high. SDN has the advantages of control separation, programmable interface, and centralized control logic. Therefore, integrating this technical concept into the smart city data management WLAN network not only can effectively solve the problems existing in the previous wireless network operation but also provide more functions according to different user needs. In this case, the traditional WLAN network is of low cost and is simple to operate, but it cannot guarantee network compatibility and performance. From a practical perspective, further network compatibility and security are a key part of industrial IoT applications. This paper designs the network architecture of smart city industrial IoT based on SDN, summarizes the access control requirements and research status of industrial IoT, and puts forward the access control requirements and objectives of industrial IoT based on SDN. The characteristics of the industrial Internet of Things are regularly associated with data resources. In the framework of SDN industrial Internet of Things, gateway protocol is simplified and topology discovery algorithm is designed. The access control policy is configured on the gateway. The access control rule can be dynamically adjusted in real time. An SDN-based intelligent city industrial Internet of Things access control function test platform was built, and the system was simulated. The proposed method is compared with other methods in terms of extension protocol and channel allocation algorithm. Experimental results verify the feasibility of the proposed scheme. Finally, on the basis of performance analysis, the practical significance of the design of a smart city wireless network hierarchical data management system based on SDN industrial Internet of Things architecture is expounded.
Highlights
According to the analysis of “Made in China 2025” proposed under the background of the new era, the development of the industrial Internet of ings has received the attention of the whole society, especially the information and communication technology and intelligent manufacturing have become the core content of China’s urban construction and development
Security and Communication Networks attributes and can transmit real-time or non-real-time traffic in the same media, but because of their incompatibility, it is impossible to run different technologies in the same physical media in the development of practice. In view of this situation, researchers have strengthened the research on timesensitive network (TSN), especially as the key content of which the smart city data management algorithm has become the focus of scientific research and exploration, which will play a positive role in the future industrial communication and automation technology innovation
Combined with the above design and analysis of the smart city data management wireless networking hierarchical system based on soft-considered network (SDN) network architecture, it can be seen that the future technology research and development of the Internet of ings must pay attention to wireless network access control, and combined with CPS, the TSN data processing algorithm is deeply explored [9]
