Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, develop simultaneously embodiment referring to the drawings,
The present invention is described in further detail.
In embodiments of the invention, the network for being used is the wireless network based on beacon (Beacon) broadcast frame, is adopted
Time division multiplex (Time Division Multiple Access, TDMA) technology.
In the wireless sensor network used by the embodiment of the present invention, there are three kinds of equipment:Network manager (Network
Manager, NM), repeater (Repeater, RP) and sensor node.
Wherein, network manager is essential equipment, is responsible for the maintenance and management of whole network.Repeater is optional equipment,
Which is responsible for the relay transmission of data, for spread radio communication apart from when use.Sensor node is terminal unit (End
Device, ED), perform the operation such as data acquisition, monitoring, detection, control.
Embodiment of the present invention network topology structure applicatory may include Star Network, tree network and chain-shaped network etc..
Wherein, Star Network can be made up of network manager and sensor node, tree network and chain-shaped network can by network manager,
Repeater and sensor node composition.Network manager, repeater and terminal unit are employed in these network topology structures,
Therefore, according to the explanation of the embodiment of the present invention with network manager, the repeater and terminal unit execution embodiment of the present invention
Method, you can realize the wireless network data transmission of the big data low-power consumption in various network topology structures.
The embodiment of the present invention, using TDMA technologies, carries out time synchronized, an enforcement of the present invention when Beacon is broadcasted
The time that Beacon receptions are arranged in example is about 2 milliseconds, broadcast cycle such as 1 second, and this set enables to enforcement of the present invention
The power consumption of the wireless sensor network of example is only 1/500 (Max) of the normally opened network of conventional receiver.Therefore, using present invention enforcement
The method of example, it is possible to reduce the power consumption of big data wireless network transmissions, the use time of prolonging wireless sensor network.Certainly,
Broadcast cycle for example can arrange 100ms, 125ms, 150ms, 200ms, 500ms, 1s etc. with longer or shorter.
Due to the restriction of TDMA patterns, excessive (generally, each sensor node that the time slot of communication can not distribute
Distribute the time slot of 1 unit length), especially in the network for needing relay extension distance.
In actual application scenarios, wireless sensor network generally existing such a case:Sensor node is big
(even gather for more time and send a bag characteristic value data such as per 30 minutes) in low-power consumption working condition in part-time,
In accumulation certain hour or after eigenvalue collection has reached activation threshold value, a larger complete data packet is sent, should
Larger complete data packet includes the acceleration information of collection, strain data, pressure data, temperature number in such as a period of time
According to etc..In short, certain sensor node needs the big data for sending burst in a certain special time period.
For sensor node, power consumption during gathered data is very low, and the power consumption of data is activation is very high, sensor
The energy great majority of node are consumed in data transfer.
It can be seen that, there is contradiction between the requirement of the transmission and low-power consumption of big data, accordingly, it would be desirable to seek between to put down
Weighing apparatus, to realize sending big data, and by power consumption limit in low-level.
Therefore, embodiments provide a kind of solution of dynamic long time slot (Dynamic Long Timeslot, DLTS)
Certainly method.

Application is played, available time slot and length are replied to sensor node by network manager.After the completion of burst transfers of data, sensor
Node discharges apllied long time slot, and long time slot is withdrawn by network manager.Repeater is only completed forwarding number in the process, not
According to basic function, in addition it is also necessary to parsing is corresponding to order, dynamic to open corresponding long time slot.Network manager, sensor node,
Repeater is monitoring (such as 1 minute) after the long time slot free time reaches certain hour, then be automatically releasable long time slot, to tackle communication not
Smooth or equipment such as accidental switches off at the situation about normally can not discharge, and is finally reached the purpose of low-power consumption.
Beacon broadcast frame is based in the embodiment of the present invention, beacon period schematic diagram is as shown in figure 1, and each beacon period
Time slot allocation example is as shown in Fig. 2 in Fig. 2, A is beacon broadcast frame slot, and slot length is 1;B is equipment access slot, when
Gap length is n;C is response time slot, and slot length is m;D is to can be used to distribute to the time slot of equipment communication, and slot length is k.
Wherein, the length relation of time slot is:K > m >=n>1.It should be noted that the slot length of A is 1, wherein 1 represents that unit is long
Degree, k, m, n are with the unit length as reference.K is to distribute to the time slot that terminal unit takes, and the slot length of k can divide
Dispensing several terminal units are used, and some time slot that each terminal unit can be taken in k (is needed according to network manager
Configuration takes).
As shown in figure 3, the big data transmission method of the wireless sensor network of the embodiment of the present invention, including:
When the sensor node needs to send big data, long Time Slot Occupancy claim frame is sent;
After the network manager receives the long Time Slot Occupancy claim frame, by the sensor node can take it is long when
Gap is distributed to the sensor node and is taken, and sends long time slot configuration communication frame;
After the sensor node receives the long time slot configuration communication frame, when in the long time slot that can be taken into which
Into data-transmission mode to send the big data, when leaving in the long time slot which can take, the sensor node enters
Enter park mode;
The network manager receives the big data in the long time slot that the sensor node can take.
Wherein, the sensor node, sends the long Time Slot Occupancy claim frame and reception in its intrinsic communication time slot
The long time slot configuration communication frame;If the sensor node is in intrinsic communication time slot or the long time slot that can be taken,
The sensor node is in data-transmission mode, and otherwise, the sensor node is in park mode.In park mode, institute
Stating sensor node only carries out data collection task, and park mode is that, for data transfer, data-transmission mode needs big
Power consumption, and when not carrying out data transmission, data transfer mould can be saved into park mode in the data is activation part of sensor node
The power consumption of formula, and the power consumption of data collection task is very little, can carry out in park mode.So, sensor section can be caused
Point can save power consumption in park mode, extend its service life.Wherein, intrinsic communication time slot refers to, in a broadcast cycle
Interior, network manager is respectively allocated to the communication time slot that each sensor node is each accounted for, in wireless sensor network
Each sensor node for, in a broadcast cycle, have a communication time slot shared by which, the communication time slot
For carrying out data communication of the sensor node in the broadcast cycle, the communication time slot is referred to as into intrinsic communication in the application
Time slot.
In common network configuration, intermediate station of the repeater as Long-range Data Transmission, be it is requisite, therefore,
In the embodiment of the present invention, the wireless sensor network is further included:Between network manager and sensor node
At least one-level repeater, passes through at least one-level repeater communication between the sensor node and network manager;Wherein,
The repeater is received after the long Time Slot Occupancy claim frame from the sensor node, and the long Time Slot Occupancy claim frame is turned
Issue first device thereon;After the repeater receives the long time slot configuration communication frame, the sensor node can be taken
Long time slot distribute to the sensor node and take, and the long time slot configuration communication frame is transmitted to into its next stage equipment;
The repeater receives the big data in the long time slot that the sensor node can take, and the big data is transmitted to
First device thereon;Wherein, the upper level equipment is upper level repeater or network manager, and the next stage equipment is
Next stage repeater or sensor node.
The repeater, receives and forwards the long Time Slot Occupancy to ask in the intrinsic communication time slot of the sensor node
Ask frame and the long time slot configuration communication frame;Wherein, if intrinsic communication time slot of the repeater in the sensor node
Or in the long time slot for taking of the sensor node, then the repeater is in data-transmission mode, otherwise, in described
Park mode is in after device.It can be seen that in the embodiment of the present invention, repeater can enter park mode to save in company with sensor node
Power consumption, extends its service life.
In actual use, it is understood that there may be network manager does not have the situation of assignable long time slot, in this case:
After the network manager receives the long Time Slot Occupancy claim frame, if not having to distribute to what the sensor node took
Long time slot, then send request status of fail frame;If the sensor node receive request status of fail frame, etc. it is scheduled when
Between after, send the long Time Slot Occupancy claim frame again;Wherein, request status of fail frame the consolidating in the sensor node
Send in having communication time slot.And then automatic request of the sensor node to long time slot is realized by the process, it is to avoid big data begins
The problem that cannot be sent eventually.
In the embodiment of the present invention, after the completion of big data is sent, the sensor node discharges the long time slot, and in institute
The long time slot state frame of release is sent in the intrinsic communication time slot for stating sensor node.
When the free time of the long time slot that the sensor node can take reach Preset Time or receive release it is long when
During gap status frames, the long time slot shared by the sensor node is reclaimed by the network manager.And then it is easy to network management
Device can be the long time slot of sensor node request distribution later.
For repeater, when receive discharge long time slot state frame when, the repeater is by the sensor node institute
The long time slot release for taking, and the release long time slot state frame is transmitted to into first device thereon;When the sensor node
When the free time of the long time slot that can be taken reaches Preset Time, the repeater release distributes to what the terminal unit took
Long time slot;Wherein, when the repeater is received in the intrinsic communication time slot of the sensor node and forwards the release long
Gap status frames.If the repeater receives the request status of fail frame that upper level equipment sends, by the request failure shape
State frame is transmitted to next stage equipment;Wherein described repeater in the intrinsic communication time slot of the sensor node is received and is forwarded
The request status of fail frame.Further realize repeater takes the consistent of time slot with sensor node when big data sends,
Forwarding for big data provides path.
In the embodiment of the present invention, the long time slot is to distribute in the general communication time slot of described wireless sensor network
One section of time slot.
Hereinafter, with reference to a detailed process, the method for the present invention is introduced.
Illustrate, in whole wireless sensor network, have p (it is of course possible to more or less) sensor node.
In the present embodiment, therefore network manager needs to send broadcast frame, and monitors in whole wireless sensor network
The state of each sensor node, repeater, and network is configured, therefore network manager is in work shape all the time
State, i.e. not dormancy always, for example, send a broadcast frame every 1S (second).
With reference to shown in Fig. 2, in each broadcast cycle, in the time slot D that can be used to distribute to equipment communication, distribute each
The each intrinsic communication time slot of sensor node, distributes p intrinsic communication time slot altogether, corresponds respectively to first sensor section
Point, second sensor node ... pth sensor node, in addition to the intrinsic communication time slot of this p, can be used to distributing to equipment and lead to
Also there is in the time slot D of letter idle unallocated time slot, the long time slot of the embodiment of the present invention is just in the unallocated time slot.
In each beacon period, at beacon broadcast frame slot A (setting unit as 1) place, network manager sends broadcast frame,
Wherein, timestamp is carried, in time slot A, all p sensor nodes enter data-transmission mode, now all p sensings
Device section receives the broadcast frame, and the timestamp according to entrained by which carries out time adjustment.Afterwards, all p sensor nodes enter
Enter park mode gathered data, to save energy expenditure.
For the P sensor node in p sensor node, (P sensor node is represented in p sensor node
Any one sensor node), just wake up in communication time slot intrinsic into P and enter data-transmission mode, to carry out data
Send, when the intrinsic communication time slots of P are left, into park mode gathered data, to save energy expenditure.
Below in conjunction with shown in Fig. 4, the course of work of P sensor node is illustrated.
When P sensor node needs to send big data, which sends long Time Slot Occupancy in the intrinsic communication time slots of P please
Seek frame.Illustrate, P sensor node sends long time slot in the intrinsic communication time slots of P for example in R broadcast cycles and accounts for
Use claim frame.In R broadcast cycles, the broadcast frame when communication direction of P sensor node is by the broadcast cycle sets
It is set to up.Long Time Slot Occupancy claim frame is upstream communication frames.
Afterwards, P intrinsic communication time slot of the P sensor node in next broadcast cycle receives network manager
The long time slot configuration communication frame for issuing or request status of fail frame.Illustrate, P sensor node is broadcasted in R+1
Long time slot configuration communication frame or request failure shape that network manager is issued are received in the intrinsic communication time slots of P in cycle
State frame.Broadcast frame setting in R+1 broadcast cycles, when the communication direction of P sensor node is by the broadcast cycle
For under.
If what is received is to ask status of fail frame, P sensor node waits a scheduled time (such as 1S)
Afterwards, long Time Slot Occupancy claim frame is sent in the intrinsic communication time slots of P again in subsequent broadcast cycle.
If what is received is long time slot configuration communication frame, parse the long time slot configuration communication frame, obtain specified by account for
Long time slot.
Afterwards, when often entering the long time slot of specified occupancy, P sensor node is also waken up and enters data-transmission mode, and
The transmission of big data is carried out, when the long time slot for specifying occupancy is left, P sensor node enters park mode gathered data,
To save energy expenditure.
After big data is sent completely, P sensor node discharges the long time slot, and sends the long time slot state frame of release.
Wherein, discharging long time slot state frame is sent in intrinsic communication time slots of P in the broadcast cycle after big data is sent completely.
Hereafter, P sensor node recovers normal operation state, i.e., only in broadcast frame slot and the intrinsic communication time slots of P
Into data-transmission mode.
In any one broadcast cycle, the data communication direction of P sensor node is by the broadcast in the broadcast cycle
Frame sets.

Long Time Slot Occupancy claim frame is received in gap, learns it is long Time Slot Occupancy claim frame that P sensor node sends.
Afterwards, network manager determines whether to distribute to the long time slot that the P sensor node takes.
If distributing to the long time slot that the P sensor node takes, then network manager is by P sensor section
The long time slot that point can take distributes to the P sensor node, and the intrinsic communication time slots of P in next broadcast cycle
Send long time slot configuration communication frame.
If not having to distribute to the long time slot that the P sensor node takes, network manager is next wide
Broadcast the intrinsic communication time slots of P in the cycle and send request status of fail frame.
Illustrate, network manager is to send long time slot in intrinsic communication time slots of P in R+1 broadcast cycles to match somebody with somebody
Put communication frame or request status of fail frame.In R+1 broadcast cycles, the communication direction of P sensor node is by the broadcast
Under the broadcast frame that network manager sends when cycle starts is set as.
After the network manager sends long time slot configuration communication frame, P sensor node can its take it is long when
Big data is uploaded in gap, now, network manager detects whether the free time of the long time slot is overtime.If overtime, P is illustrated
Sensor node does not have data to upload for a long time, and then the long time slot for distributing to P sensor node is received by network manager
Return, to avoid the waste of time interval resource.The long time slot for reclaiming can be again assigned to P sensor node or other biographies afterwards
Sensor node is used.
During the free time of long time slot is not timed-out, when the network manager receives the long time slot state of release
During frame, illustrate that the big data of P sensor node has been sent, it is not necessary to be further continued for taking the long time slot, and then network
The long time slot for distributing to P sensor node is withdrawn by manager.Wherein, discharging long time slot state frame has been sent in big data
Receive in the intrinsic communication time slots of P in broadcast cycle into after.
Below in conjunction with the course of work for shown in Fig. 6, illustrating repeater.
Repeater receives long Time Slot Occupancy claim frame in the intrinsic communication time slots of P, and forwards it to upper level equipment,
Such as upper level repeater, or network manager.Illustrate, P of the repeater for example in R broadcast cycles inherently communicates
Long Time Slot Occupancy claim frame is received in time slot, and forwards it to upper level equipment.
Afterwards, if P intrinsic communication time slot of the repeater in next broadcast cycle receives request status of fail
Frame, then be directly forwarded to next stage equipment, such as next stage repeater or P sensor node.
If P intrinsic communication time slot of the repeater in next broadcast cycle receives long time slot configuration communication frame,
The long time slot configuration communication frame is then parsed, the long time slot specified by long time slot configuration communication frame is distributed to into P sensor node
Use, and long time slot configuration communication frame is transmitted to into next stage equipment.
Illustrate, repeater is to receive long time slot configuration in intrinsic communication time slots of P in R+1 broadcast cycles to lead to
Letter frame or request status of fail frame, and long time slot configuration communication frame is transmitted to into next stage equipment.
Afterwards, repeater detects whether the free time of the long time slot is overtime.If overtime, P sensor node is illustrated
Do not have data to upload for a long time, and then the long time slot for distributing to P sensor node is withdrawn by repeater, to avoid time slot from providing
The waste in source.The long time slot for reclaiming can be again assigned to P sensor node afterwards or other sensor nodes are used.
During the free time of long time slot is not timed-out, when the repeater receives the long time slot state frame of release
When, illustrate that the big data of P sensor node has been sent, it is not necessary to be further continued for taking the long time slot, and then repeater
Long time slot state frame will be discharged and be transmitted to upper level equipment, and the long time slot for distributing to P sensor node is withdrawn.Wherein,
