Cognitive radio and edge calculation method based on industrial wireless network

Abstract

The invention discloses a cognitive radio and edge calculation method based on an industrial wireless network. According to the method, a cognitive radio and edge calculation model architecture basedon the industrial wireless network is erected firstly. Secondly, system models are established, including a network model, a service model and a calculation model. Afterwards, distributed random optimization is described, including system state space, motion space and reward and optimization targets. Finally, optimal distribution motion minimizing the online calculation complexity is sought by useof dynamic random optimization and an augmented Markov decision process (MDP), wherein a state transition probability is calculated firstly, then a system reward is updated, and finally the augmentedMDP is reconstructed and joint resource management is performed. Through experimental tests, compared with a conventional method, the method can obtain higher system benefits, provide higher throughput and reduce system transmission delay under different spectrum arrival rates and numbers of CRECs.

Description

technical field [0001] The invention relates to the technical field of industrial wireless networks, in particular to a method for joint resource management of cognitive radio and edge computing based on industrial wireless networks. Background technique [0002] After the first industrial revolution about 250 years ago, mankind has experienced three industrial revolutions. Just recently, the Fourth Industrial Revolution, or Industry 4.0 as it is called, has gained a lot of attention in academia and industry. In this industrial process, the traditional manufacturing industry is merging with emerging electronic technologies, resulting in many composite technologies such as industrial networks, industrial big data analysis, automatic fault repair, intelligent supply chain management, and personalized production. [0003] Wireless network has become a key technology in industrial network because of its convenience in equipment deployment. However, the current situation is tha...
