A base station dormancy method based on sensor terminal energy harvesting

Abstract

The invention belongs to the field of wireless network communication, and provides a base station sleep method based on energy harvesting of sensor terminals. The method comprises the following steps: energy harvested by each sensor served by a base station from the base station is normalized, and an energy harvesting value between 0 and 1 is statistically obtained every hour on the hour; the normalized energy harvesting value of each sensor is uploaded to the base station, and the base station calculates a geometric mean of all the energy harvesting values to obtain a base station closing possibility; the base station starting / closing working status is randomly controlled through the base station closing possibility. The method provided by the invention has the advantages that through a comprehensive consideration of the energy harvested by all the sensors, the base station starting / closing status can be reasonably controlled by the base station, so that energy consumption of the base station can be more effectively reduced without the sensors being charged by an external power supply, which achieves the self-sufficiency advantage of devices with low power consumption, as well as energy conservation.

Description

technical field [0001] The invention belongs to the field of wireless network communication, relates to the Internet of Things, and in particular relates to a base station dormancy method based on energy harvesting of sensor terminals. Able to meet the specified QoS (Quality of Service) requirements. Background technique [0002] With the development of modern communication services, it is required that future wireless communication must have higher spectral efficiency. At the same time, due to the aggravation of global environmental pollution, the requirements for energy conservation and emission reduction in the communication industry are becoming more and more stringent. This requires that the future wireless communication system must solve the problem of spectrum and environmental protection at the same time. In other words, it is required that the future wireless communication system should reduce energy consumption as much as possible, avoid greenhouse gas emissions,...

AI Technical Summary

Problems solved by technology

The dormant mode can be switched on and off according to the fluctuation of the load of the base station, so as to bring high energy efficiency gains, but at the same time, it will also affect other network performance

On the one hand, turning off a large number of base stations can save more energy; on the other hand, turning off too many base stations will degrade the user's service quality

And, considering that devices in the Internet of Things need to harvest energy from RF signals to power themselves, the introduction of the sleep strategy will also affect the number of RF signal sources around the device, which will further affect data transmission

Therefore, the interaction between these two technologies leads to how to design the dormancy strategy to become an urgent problem to be solved.
