Abstract
Wireless networks, as a crucial component of modern communication technologies, have drawn increasing attention regarding their energy consumption issues. To address the limitations of traditional battery-powered approaches, this study focuses on the research of energy harvesting and transmission technologies, aiming to achieve sustainable operation of wireless networks by optimizing energy utilization efficiency. Based on energy harvesting communication theory, a joint optimization fr amework integrating radio frequency energy harvesting and data transmission is proposed, which can dynamically adjust resource allocation strategies between energy harvesting and data transmission. By incorporating machine learning algorithms, the system's adaptability to complex environments is further enhanced, and energy management protocols applicable to various scenarios are designed. Experimental results demonstrate that the proposed scheme significantly improves network energy utilization and extends device lifespan, increasing the network lifecycle by approximately 30% compared to conventional methods. Additionally, this paper innovatively proposes a multi-user collaborative energy harvesting mechanism, effectively resolving the problem of uneven energy distribution and thereby improving the overall performance stability of the system. The research not only provides new insights into energy management for wireless networks but also lays a theoretical foundation for the development of future green communication technologies.
