[Abstract]:With the development of science and technology, the Wireless Sensor Network (WSN) technology has made great progress and has shown great prospects. However, most of the nodes in wireless sensor networks are powered by button batteries, and the battery energy is limited, which greatly restricts the work of ensuring the whole network. Reliability. And a large number of use and replacement of batteries not only improve the cost but also pollute the environment. Therefore, how to rationally and efficiently utilize the limited energy of sensor nodes is the key problem in the research of wireless sensor networks. At present, some domestic and foreign scholars have adopted some optimization algorithms to balance the various nodes of the network. Energy consumption in order to improve the life cycle of the network. With the rapid development of Wireless Power Transfer (WPT) in recent years, this provides the best solution to solve wireless sensor network node wireless power supply and improve the life cycle of the network. This article is limited to the energy of nodes in the wireless sensor network. An integrated wireless power supply sensor network with bidirectional transmission of energy is studied. A wireless power supply network model is established to analyze the energy transmission characteristics of nodes and the characteristics of related networks. An ant colony algorithm based on weight preference is proposed to optimize the energy link, find an optimal link, and finally achieve the most network life cycle. Three basic transmission models of wireless power supply network are summed up. Then from the physical layer of wireless sensor network, the specific model of the circuit is given and the power control strategy of the node is analyzed. The research status of wireless sensor network, radio transmission technology and wireless power supply of sensor network nodes are first studied. The work principle, the protocol stack and the network topology of the wireless sensor network are analyzed, the basic principle of the radio energy transmission technology is introduced, and the compensation structure is analyzed. Finally, the wireless power supply sensor network model is established, and the detailed comparison analysis and the traditional wireless network are compared. Then, the paper studies the model of wireless power supply sensor network. This paper introduces the node attribute and network operation mechanism of the network, and establishes a mathematical model for the link optimization of the wireless power supply network. Three effectiveness indexes of time delay are used as the criterion of link optimization. The optimal link is obtained by using ant colony algorithm based on weight preference, and the optimal link is obtained. Then, the research algorithm of power control for sensor nodes should be used in network layer or data link layer. The power control of wireless power supply sensor network is studied over the physical layer. The topology structure of the two-way transmission of energy based on radio energy transmission is analyzed. The power control is carried out for the topology structure. Phase shift PWM control strategy is adopted to control the power of the node, and the power of three node radio transmission modes is obtained. In the end, the paper simulates the ant colony algorithm based on weight preference through MATLAB programming, and verifies the feasibility and effectiveness of the algorithm for link optimization problems. By building an experimental platform, it verifies the specificity of the bidirectional transmission of the circuit topology of LCL, and verifies the three transmission modes of the wireless power supply network. Power control. Through the study of radio energy transmission technology in wireless sensor network nodes, this provides a new solution for the limited energy of wireless sensor networks, thus effectively promoting the development of wireless sensor network technology and the development of radio energy transmission application technology, for the follow-up. The related research provides the theoretical basis and reference significance.
