Abstract
The present invention provides a kind of base station dormancy methods based on the harvesting of sensor terminal energy, belong to wireless communication field.In this method, each sensor that base station services is normalized from the energy that base station is gathered in, every integral point counts the energy harvesting value between one 0~1, energy harvesting value after the normalization of each sensor is uploaded to base station, geometric mean calculating is carried out to all energy harvesting values by base station, the closing probability of base station is obtained, probability STOCHASTIC CONTROL base station unlatching/closing working condition is closed by base station.The energy that the present invention is gathered in by comprehensively considering each sensor, enable what base station rationally controlled itself to open or close state, reached not external power supply to sensor charge while, the effect of the energy consumption of base station is more saved, there is the self-centered advantage of low power consuming devices and energy-efficient meaning.
Description
Technical field
The invention belongs to wireless communication fields, are related to Internet of Things, and in particular to one kind is based on sensor terminal energy
The base station dormancy method of harvesting, by using base station the control of dormancy strategy, makes to have in large-scale wireless communication network
The sensor of energy harvesting function can reach defined QoS (service quality) requirement.
Background technique
With the development of modern communications business, it is desirable that following wireless communication must have higher spectrum efficiency.Meanwhile
Due to the exacerbation of Globalization pollution, the requirement for communications industry energy-saving and emission-reduction is also increasingly stringenter.This requires futures
Wireless communication system must solve spectrum issue and environmental issue simultaneously.In other words, future wireless system system is exactly required
System will reduce as much as possible energy consumption, avoid the discharge of greenhouse gases while can continue to improve spectrum efficiency, realize
" green " communication.In order to cope with this problem, the research of energy-saving network framework and power-saving technology causes the attention of academia, and
And gradually become current research emphasis.
In numerous power-saving technologies, radiofrequency signal is collected from ambient enviroment to have developed into charging of mobile devices
For a potential and efficient technology.Specifically, the basic physical module for collecting energy from radiofrequency signal around is one
A RECTIFYING ANTENNA, RF energy present in environment can be converted into DC voltage by it.Pass through the radio frequency gathered in from environment
Energy supports it to run and the transmission of data, and mobile device can extend the service life of battery, and the device of low-power is very
It extremely can be with permanent operation.This is an extremely attractive technology, particularly in view of most low-power consumption Internet of Things is set
It is standby to require to charge, so this Internet of Things application will become the Killer application of 5G.
On the other hand, introducing suspend mode to base station is also an effectively method, it can save cellular network
Energy consumption.Load in the base station of synchronization different location, place cellular cell differs greatly；Meanwhile in same base station
Load in its place cellular cell of different moments changes greatly.It can be according to the fluctuation feelings of load of base station using suspend mode
Condition, accordingly closed state is opened in switching, to bring the gain of high energy efficiency, but also will affect other performances of network simultaneously.One
Aspect, a large amount of base stations of closing can save more energy；On the other hand, excessive base station, the service quality meeting of user are closed
Deterioration.Also, in view of the equipment in Internet of Things needs to collect the case where energy is come to power itself, suspend mode from radiofrequency signal
The introducing of strategy also will affect the quantity of radio-frequency signal source around equipment, this will further influence data transmission.Therefore both
So as to cause dormancy strategy, how this is designed to urgent problem to be solved for interaction between technology.
Summary of the invention
For present problems, the present invention provides a kind of base station dormancy methods based on the harvesting of sensor terminal energy, adopt
With dormancy strategy, by comprehensively considering the energy of each sensor harvesting, enable base station rationally control itself open/close shape
State.Reached not external power supply to sensor charge while, more save the effect of the energy consumption of base station, have it is low
The self-centered advantage of power consuming device and energy-efficient meaning.
The present invention provides a kind of base station dormancy methods based on the harvesting of sensor terminal energy, divide following steps:
Step 1: the sensor of base station service is numbered.
Step 2: each sensor being normalized from the energy that base station is gathered in, every integral point counts one 0~1
Between energy harvesting value.
Step 3: every integral point will be uploaded to base station to the energy harvesting value after the normalization of each sensor, by base station pair
All energy harvesting values carry out geometric mean calculating, obtain the closing probability of base station.
Step 4: probability, STOCHASTIC CONTROL base station unlatching/closing working condition are closed by obtained base station.
Compared with the existing technology, the present invention uses dormancy strategy, by comprehensively considering the energy of each sensor harvesting, makes base
Itself unlatching/closed state can rationally be controlled by standing, reached not external power supply to sensor charge while, more save
The effect of the energy consumption of base station has the self-centered advantage of low power consuming devices and energy-efficient meaning.
Detailed description of the invention
Fig. 1 is a kind of overall flow schematic diagram of the base station dormancy method based on the harvesting of sensor terminal energy of the present invention.
Specific embodiment
Illustrate the technical solution of the method for the present invention with reference to the accompanying drawings and examples.
As shown in Figure 1, the base station dormancy method provided by the invention based on the harvesting of sensor terminal energy, including step
101~step 104 is below specifically described each step.
Step 101: being numbered 1,2,3 to the sensor of base station service ..., N, N are positive integer.
Step 102: each sensor is normalized every integral point from the energy that base station is gathered in, and counts one 0
Energy harvesting value E between~11,E2,…,EN, and base station will be uploaded to the energy harvesting value after the normalization of each sensor,
It counts and uploads 24 times daily.
Step 103: carrying out geometric mean calculating by all energy harvesting values of the base station to acquisition, obtain the closing of base station
Probability
The closing probability of base station is calculated per hour once, then according to current probability control switch.
Step 104: probability q, STOCHASTIC CONTROL base station unlatching/closing working condition are closed by obtained base station.
The present invention enables base station rationally to control itself unlatching/closed state by the energy of comprehensive each sensor harvesting,
It realizes the saving of base station energy consumption, there is the self-centered advantage of low power consuming devices and energy-efficient meaning.
