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

A kind of base station dormancy method based on the harvesting of sensor terminal energy
Technical field
The invention belongs to wireless communication field, relate to Internet of Things, be specifically related to a kind of base station dormancy method based on the harvesting of sensor terminal energy, in large-scale wireless communication network, by adopting the control of dormancy strategy to base station, the transducer with energy harvesting function is enable to reach QoS (service quality) requirement of regulation.
Background technology
Along with the development of modern communications business, require that following radio communication must have higher spectrum efficiency.Meanwhile, that pollutes due to Globalization increases the weight of, and the requirement for communications industry energy-saving and emission-reduction is also more and more stricter.This just requires that following wireless communication system must solve spectrum issue and environmental issue simultaneously.In other words, require that future broadband wireless communication systems while can continuing to improve spectrum efficiency, will reduce energy ezpenditure, avoid the discharge of greenhouse gas as much as possible exactly, realize " green " communication.In order to tackle this problem, the research of energy-saving network framework and power-saving technology causes the attention of academia, and progressively becomes current research emphasis.
In numerous power-saving technologies, from surrounding environment, collect radiofrequency signal developed into a potential and efficient technology to charging of mobile devices.Specifically, from around radiofrequency signal, the basic physical module of harvest energy is a RECTIFYING ANTENNA, and it can convert the radio-frequency (RF) energy existed in environment to direct voltage.Supported the transmission of its operation and data by the radio-frequency (RF) energy of gathering in from environment, mobile device can extend the useful life of battery, and lower powered device even can forever operate.This is an extremely attractive technology, especially considers that most low-power consumption internet of things equipment all needs charging, so the application of this Internet of Things will become the Killer application of 5G.
On the other hand, introducing park mode to base station is also an effectively method, and it can save the energy consumption of cellular network.In the base station of synchronization diverse location, the load in its cellular cell, place differs greatly; Meanwhile, the load variations in same base station not in the same time in its cellular cell, place is larger.Adopt park mode according to the fluctuation situation of load of base station, can to switch accordingly and open closure state, thus bring the gain of high energy efficiency, but also can affect other performances of network simultaneously.On the one hand, more energy can be saved in a large amount of base station of closing; On the other hand, close too much base station, the service quality of user can deterioration.Further, consider that the equipment in Internet of Things needs harvest energy from radiofrequency signal to come to the situation of power itself, the introducing of dormancy strategy also will affect the quantity of radio-frequency signal source around equipment, and this will affect transfer of data further.Therefore these two kinds of technology interphase interaction thus cause dormancy strategy how this design and become problem demanding prompt solution.
Summary of the invention
For present problems, the invention provides a kind of base station dormancy method based on the harvesting of sensor terminal energy, have employed dormancy strategy, by considering the energy of each transducer harvesting, enabling base station conservative control self On/Off state.Reach not external power supply, to while transducer charging, to save the effect of the energy ezpenditure of base station more, there is the self-centered advantage of low power consuming devices and energy-conservation meaning.
The invention provides a kind of base station dormancy method based on the harvesting of sensor terminal energy, point following steps:
Step 1: the transducer of base station service is numbered.
Step 2: be normalized by the energy that each transducer gathers in from base station, every integral point adds up the energy harvesting value between 0 ~ 1.
Step 3: every integral point, is uploaded to base station by the energy harvesting value after each transducer normalization, carries out geometric mean calculating, obtain the closedown probability of base station by base station to all energy harvesting values.
Step 4: close probability by the base station obtained, the operating state of STOCHASTIC CONTROL base station On/Off.
Relative to prior art, the present invention adopts dormancy strategy, by considering the energy of each transducer harvesting, enable base station conservative control self On/Off state, reach not external power supply to transducer charging while, save the effect of the energy ezpenditure of base station more, there is the self-centered advantage of low power consuming devices and energy-conservation meaning.
Accompanying drawing explanation
Fig. 1 is the overall flow schematic diagram of a kind of base station dormancy method based on the harvesting of sensor terminal energy of the present invention.
Embodiment
The technical scheme of the inventive method is described below in conjunction with drawings and Examples.
As shown in Figure 1, the base station dormancy method based on the harvesting of sensor terminal energy provided by the invention, comprises step 101 ~ step 104, is specifically described below to each step.
Step 101: 1 is numbered, 2,3 to the transducer of base station service ... N, N are positive integer.
Step 102: every integral point, is normalized the energy that each transducer gathers in from base station, the energy harvesting value E between adding up 0 ~ 1 1, E 2..., E n, and be uploaded to base station by the energy harvesting value after each transducer normalization, add up every day and upload 24 times.
Step 103: by base station, geometric mean calculating is carried out to all energy harvesting values obtained, obtain the closedown probability of base station q = E 1 E 2 · · · E N N .
The closedown probability of base station be calculating per hour once, then according to current probability control switch.
