[Abstract]:The rapid development of wireless communication technology also brings more and more prominent energy consumption problem. The purpose of data and Energy Integrated Communication Networks, DEINs) is to solve the problem of energy consumption in traditional infinite communication system. To a certain extent, to achieve wireless communication energy saving and emission reduction. Based on the related research background of digital energy integration network and the corresponding network service index, quality of Service, QoS, this paper focuses on two aspects of logarithmic energy integration network, that is, the resource allocation and transmission strategy of digital energy integrated network. Firstly, this paper introduces the research status and related technologies of digital energy integrated wireless communication network, mainly including energy collection technology, digital energy integrated transmission technology. The resource allocation in the digital energy integration network and the fusion application of the digital energy integration network with other specific networks. Energy collection technology and digital energy transmission technology are the technical foundation of digital energy integrated network. In this paper, the problem of resource allocation in digital energy integrated networks is described. The influence factors of wireless transmission energy need to be considered in the resource allocation strategy of digital energy integration networks. Then, this paper studies the transmission decision of uplink data, downlink transmission data and energy in digital energy integrated network. Based on the general network system model, the Markov decision process analysis system model is used to satisfy the uplink transmission and downlink transmission with a certain packet loss rate constraint. An optimal decision analysis model for the maximum return of system throughput is established. By solving the model, the probability of each decision in a system state is obtained. Finally, the simulation shows the probability of each decision under the relevant system state, and analyzes and compares the system throughput under the general strategy and the optimal strategy, and explains the performance of the optimal strategy. Finally, this paper studies the resource allocation in digital-energy transmission. Based on the traditional cellular network, considering the downlink digital transmission and uplink data transmission system model, the downlink energy transmission is used to satisfy the energy needed for uplink transmission data, and the system downlink throughput is established as the optimization goal. Uplink and downlink joint optimization model to satisfy the energy required for uplink data transmission. In addition, in multi-user systems, the fairness factor is taken into account, and the maximum minimum model is established. The results of resource allocation of the system are described through the simulation of the model, and the influence of fairness factors is explained by simulation.
