Research On Dynamic Resource Allocation Scheme In Industrial Internet Of Things

With the continuous development of industrial Internet of Things(IIo T),the security and reliability of the system become more and more important.One of the keys to solve the security problem is to ensure the reliability of communication between nodes.Therefore,what kind of scheduling mechanism or technology should be adopted to ensure the reliability of transmission has aroused a heated debate.In addition,the scale of wireless information transmission between nodes increases greatly,and the amount of data that nodes need to perceive,process,and transmit has increased substantially,which also leads to the increasing of the nodes' power consumption.However,since the power resources available to the nodes are limited,how to properly allocate resources to reduce the system's power consumption and improve the system's energy efficiency is an urgent problem to be solved under the premise of satisfying the system's demand for service quality.Through the study of the dynamic time resource and power resource allocation mechanism in the IIo T,this paper improves the performance of the system while satisfying the stability of the queue,that is,ensuring the stability and security of the system.Firstly,the slot frequency hopping technology(TSCH)is used to ensure the reliability of wireless data transmission.Based on the TSCH,the nodes in the network minimize the power consumption of the nodes through dynamic resource allocation,thereby improving the resource utilization rate.Secondly,by allocating resource dynamically,the energy efficiency of the node is maximized,which increases the system's capacity and reduces the system overhead at the same time.Finally,the dynamic resource allocation of the node based on the wireless power communication network(WPCN)maximizes the energy efficiency of the system,thereby prolonging the service life of the network.On the one hand,by dynamically allocating resource of nodes reasonably can ensure the efficient utilization of resources and realize green communication.On the other hand,it can enhance the performance of the system and thus meet the different needs of users.Through theoretical analysis,based on three different system models and research focuses,this paper proposes three different algorithms to allocate resources dynamically to improve the network the system's performance.With the help of system simulation,the rationality and superiority of the proposed algorithm are verified.
