Fig. 1 is to show the channel dispatch side that the host node in self-organizing subnet according to an embodiment of the invention is carried out
The flow chart of method.
As shown in figure 1, the channel scheduling method 100 that the host node in self-organizing subnet in Fig. 1 is carried out includes：Step
S101, in response to newly-built self-organizing subnet, multiple wireless channels are initially selected by the host node in newly-built self-organizing subnet
In working channel of first wireless channel as the self-organizing subnet, wherein, the multiple wireless channel includes being exclusively used in passing
The preferential wireless channel of defeated prioritized data and the non-preferential wireless channel in addition to the preferential wireless channel；Step S102,
The common-channel interference indicated value of the multiple wireless channel is monitored and maintained by host node；Step S103, in response to the self-organizing
The working channel of subnet is switched to the requirement of second wireless channel, by host node according to the common-channel interference indicated value maintained come
Carry out the channel switching, wherein, host node that the working channel of the self-organizing subnet is used in the self-organizing subnet and/
Or the communication from node.The self-organizing subnet is the region limited network to limit by region keys.
In the present embodiment, the working channel of self-organizing subnet, monitoring are initially selected and maintains all wireless channels
Common-channel interference indicated value, according to the common-channel interference indicated value maintained to carry out channel switching the step of be all by this from
The host node in subnet is organized to carry out, without extra access point apparatus（Access Point equipment, AP equipment）.
Secondly, if there is multiple self-organizing subnets, it can be monitored and safeguarded in a distributed manner by the host node in each self-organizing subnet
Common-channel interference indicated value, uniformly monitor and safeguard that common-channel interference indicates without increasing extra access point apparatus
Value.And the host node can also carry out the work of the self-organizing subnet of oneself according to the common-channel interference indicated value maintained
The channel switching of channel, can so manage all devices in the self-organizing subnet of oneself in units of self-organizing subnet
（Including host node and from node）Communication channel, the action of the scheduling of channel can be so distributed to each self-organizing subnet
Host node on, so as to improve the efficiency of the scheduling of channel, existing hardware resource can also be made full use of, so as to save into
This.
In one embodiment, the requirement in response to channel switching, is done by host node according to the common channel maintained
Disturbing indicated value can include to carry out the step S103 of the channel switching：In response to being switched to preferentially from non-preferential wireless channel
The requirement of wireless channel, the host node are switched to the preferential wireless communication that its common-channel interference indicated value is less than the first predetermined threshold
Road；Requirement in response to being switched to non-preferential wireless channel from preferential wireless channel, the host node are switched to minimum common
Channel disturbance indicated value or its common-channel interference indicated value be less than the second predetermined threshold non-preferential wireless channel.
On how to monitor and maintain the method for common-channel interference indicated value can be in same applicant July 26 in 2013
Found in the pending Chinese patent application 201310319684.7 that day submits to Patent Office of the People's Republic of China, quoted invest this herein,
Without repeating.
Certainly, in a step 101, the first nothing in multiple wireless channels can also be initially selected through the above way
Working channel of the line channel as the self-organizing subnet, i.e., by selecting its common-channel interference indicated value to be less than the first predetermined threshold
Preferential wireless channel, otherwise selection with minimum common-channel interference indicated value or its common-channel interference indicated value be less than second
The non-preferential wireless channel of predetermined threshold.
In one embodiment, if the host node determines that its common-channel interference indicated value is not present to be made a reservation for less than first
The preferential wireless channel of threshold value, then carry out determining whether there is its common-channel interference indicated value after the scheduled time less than first
The step of preferential wireless channel of predetermined threshold.
In one embodiment, the host node can monitor the common-channel interference of multiple wireless channels with predetermined period
Indicated value.The predetermined period is, for example, 10 seconds, 20 seconds ... etc..
The channel scheduling method 100 can also include：Step S104（It is not shown）, it is described from group in response to entering from node
Subnet is knitted, by the host node from described from the common-channel interference of the multiple wireless channels maintained described in node reception from node
Indicated value, the current common-channel interference indicated value maintained as the host node.So, monitoring channel altogether is not reached in host node
When disturbing the cycle of indicated value, the common-channel interference instruction maintained from node directly can be received at node from what is newly added
Value, so as to obtain as far as possible current and more accurately common-channel interference indicated value.
In one embodiment, in the case where multiple self-organizing subnets be present, by except the multiple radio communication
Independent channel beyond channel to each self-organizing subnet send respective region keys at the time of can be synchronous.This
In the case of, at the time of some actions of multiple self-organizing subnets can be calibrated at the time of synchronous using this, for example, channel switches
Etc..The independent channel can be the channel of for example outside infrared signal.So compared to the cycle in common WiFi system
Property Beacon mechanism, can highly precisely synchronously to each self-organizing subnet send respective region keys at the time of, go forward side by side
At the time of some actions of the multiple self-organizing subnets of one step calibration, for example, channel switching etc..For example, in some self-organizings
, can be since at the time of sending respective region keys to each self-organizing subnet, by needing when net needs to carry out channel switching
The host node delay respective different time delay carried out in the self-organizing subnet of channel switching is the multiple to be monitored
The step of common-channel interference indicated value of wireless channel and the channel is carried out according to the common-channel interference indicated value monitored
The step of switching.The host node in multiple self-organizing subnets can so be avoided while be switched to the conflict of a certain wireless channel,
Cause the too big situation of the wireless channel load, on the contrary, this host node for needing channel to switch that can be postpones different prolong
The slow time, and after some host nodes have switched channel, current common-channel interference indicated value is just monitored, it is each so as to obtain
The more accurately current loads of wireless channel and interference, and then be more accurately made whether to carry out channel switching or which is switched to
The step of channel.This is also by the message introduction in the mechanism stepped back at random afterwards.
The channel scheduling method 100 can also include：Step S105（It is not shown）, it is described from group in response to entering from node
Subnet is knitted, from node as described in the host node certification, to use the work of the self-organizing subnet described in after certification from node
Communicated as channel.This certification can be carried out in many ways, for example, by host node more currently from this from
Whether the region keys and the currently stored region keys of host node in the signal that node receives are identical, if identical, certification
By if it is different, then certification does not pass through.Certainly, this mode is only example, and those skilled in the art are also contemplated that other
Authentication mode.
The channel scheduling method 100 can also include：Step S106（It is not shown）, to be monitored in response to host node described more
The common-channel interference indicated value of individual wireless channel, suspend or reduce in the self-organizing subnet from node in the self-organizing subnet
Wireless channel on communication activity.So do, can prevent host node from referring in the common-channel interference for monitoring multiple wireless channels
During indicating value, by each in the self-organizing subnet of their own from being communicated on the working channel of oneself between node and
Caused noise jamming, so as to prevent following situation：Host node mistakenly indicates the common-channel interference of the working channel of oneself
Value monitoring is very big, so as to be mistakenly considered to need that the current operating channel of their own is switched into other channels, causes ceaselessly to cut
Change channel.
Therefore, according to each embodiment of the present invention, can under self-organizing network environment as far as possible using existing resource,
Carry out distributed channel dispatch efficiently and exactly.
Fig. 2A is the environment schematic of self-organizing subnet for showing to be applied according to Fig. 1 channel scheduling method.
As shown in Figure 2 A, four self-organizing subnets be present（Organized Wireless Group, OWG）1、2、3、4.Often
Individual self-organizing subnet can be the P2P based on WiFi-Direct（Peer-to-Peer）Subnet, also can be an Ad-hoc subnet
Cluster, confined area network etc..Generally, a host node and 0 or multiple from node can be contained in each subnet.
In each self-organizing subnet, generally, host node maintains the company between each node inside subnet session and subnet
Connect；When leaving the subnet from node in a subnet, host node delete that this leaves from all inside subnet of node
Link information simultaneously notifies other inside same subnet from node；When host node leaves, a new host node is from node
Middle generation, and the host node left needs to transfer all host node information and function to new host node.Each self-organizing
Each node in net needs a radio communication channel to be communicated, broadcast etc. action.According to each reality of the present invention
Apply example, the respective host node in each self-organizing subnet 1,2,3,4 can voluntarily carry out channel dispatch, such as initially select
Working channel, monitoring and maintain the common-channel interference indicated value of some or all of wireless channels and cut needing to carry out channel
Channel switching is carried out when changing, this channel is managed without wanting access point apparatus or other management equipments of individualism
Scheduling, so as to realize under self-organizing network environment as far as possible using existing resource, efficiently and exactly divided
The channel dispatch of cloth.
Fig. 2 B are the schematic diagram of a scenario for showing to be applied according to Fig. 1 channel scheduling method.
As shown in Figure 2 B, it is possible, firstly, to determine to be exclusively used in one or more preferential wireless channels of transmission preferences data（Example
Such as, the B class channels in Fig. 2 B, the B class channels are usually low interference channel or are clear channel, are especially remained for needing in advance
Interim high speed data requirements or the subnet for greatly being disturbed current operating channel is wanted to be switched on B class channels）And except
Non-preferential wireless channel beyond preferential wireless channel（For example, the A class channels in Fig. 2 B, i.e., allow high on the A class channels
Common-channel interference is present, namely allows many self-organizing subnets to share the channel）.
The host node according to the present invention is distributed carry out channel dispatch in the case of, whenever being initially formed one by host node
Individual self-organizing subnet（Or region limited network）When, the host node selects a working channel first according to certain rule.With
Afterwards, other may be added in same subnet from node.Certain rule will be described in detail below.Practically, stable
System in there may be many self-organizing subnets, some of which subnet works on the same channel.In A class channels, when having
When subnet is in serious common-channel interference, B class channels may be dispatched or switched to the host node in the subnet, so as to obtain
The improvement of communication efficiency.For example, as shown in Figure 2 B, two subnets are switched work to B class channels.Under certain conditions, work
The subnet made under B class channels is also required to be switched back to by host node on the A class channels of high interference.The process of channel switching is also
It will be described in detail below.
Pay attention to, " scheduling " referred in the disclosure（It may include " to distribute ", " switching " etc.）, " distribution ", " switching " etc.
Etc. being to whole subnet " scheduling ", " distribution ", " switching " channel, rather than channel is distributed some single mobile device, i.e.
After " scheduling ", " distribution ", " switching " the entirely channel of subnet, all mobile devices inside whole subnet（Including main section
Point and from node）Can " scheduling ", " distribution ", " switching " channel on carry out data transmission, including both communication,
To indefinite Body Broadcast etc..
As for A classes channel and B class channels（Non-preferential channel and priority channel）Example dividing mode and criterion, can be with
Determine to be exclusively used in the preferential wireless channel of transmission preferences data by following：Its utilization is found from all available wireless channels
Rate is less than one or more wireless channels of the first predetermined threshold, as one or more of preferential wireless channels.It is and wireless
The utilization rate of channel can be determined with least one in following：The availability of frequency spectrum of wireless channel；The common letter of wireless channel
Disturb indicated value in road；The number of the access device of wireless channel；Average packet loss ratio on the wireless channel.On this point,
The pending Chinese patent application that same applicant submits on July 26th, 2013 to Patent Office of the People's Republic of China can also be referred to
201310319684.7, quoted invest this herein, and do not repeated.
Fig. 3 A are shown in the channel scheduling method according to Fig. 1 in initialization, monitoring and maintenance common-channel interference indicated value
And the example flow diagram from a specific example in the case of node addition.
Assuming that：Each mobile node can monitor the respective letter altogether of multiple wireless channels in surrounding environment on startup
Road disturbs, and then sometime, the mobile node may add a certain region and be limited subnet, for example, mentioned in the disclosure from
Organize subnet.So, the situation of the respective common-channel interference of multiple wireless channels in surrounding environment can be maintained
At each distributed mobile node, maintained without individually such as access point apparatus or other management equipments, this
Sample can improve the utilization rate of resource, also improve processing speed.
Certain rule independently selection channel and switching channel can be based on as the host node of a self-organizing subnet.Example
Such as but without limitation, certain rule can be for example：
As shown in Figure 3A, in step S301, for example, turning into the host node of a self-organizing subnet in a mobile node
（Also referred to as the host node establishes a self-organizing subnet）When, it can scan and sense and be divided into all wireless of A classes and B classes
The common-channel interference indicated value of channel, to form the table of common-channel interference indicated value, if the B sensed in B class channels
The common-channel interference indicated value of class priority channel is less than the first predetermined threshold, such as Vth1, then the B class channels can preferentially be used
Working channel as the self-organizing subnet.Wherein it is possible to by Vth1The environmental disturbances being taken as in background, such as very little
Value, such as 00000010 in the case of being represented with 8 bits2（Subscript 2 represents binary numeral）, in such a case it is possible to
Ensure once only to be taken by a self-organizing subnet on B class priority channels, as long as because B classes priority channel is by a self-organizing
Subnet takes, and its common-channel interference indicated value is certainly more than the environmental disturbances value of background, therefore other self-organizing subnets determine the B
Class priority channel is unavailable, therefore will not select（Or being switched to afterwards）On the B class channels.Certainly, the Vth1Value be only
Example, those skilled in the art are contemplated that other values to realize different purposes.
Otherwise, in step s 302, whether host node can will have minimum common-channel interference indicated value in A class channels
Or its common-channel interference indicated value is less than the second predetermined threshold Vth2A non-preferential channel of A classes, as the self-organizing subnet
Working channel.Again, it is to be noted that host node that the working channel of the self-organizing subnet can be used in the self-organizing subnet
And/or the communication from node that may be added in the future.
Then, in step S303, from node（Certainly, it may not be referred to as from node also now, be properly termed as movable joint
Point）Often multiple wireless channels can also be sensed, to obtain the common-channel interference indicated value of each wireless channel, at this
When entering the self-organizing subnet established by the host node from node（For example, by whether receiving self-organizing from node
The specific region key of broadcast etc. mode is netted to determine whether to enter the self-organizing subnet）, can be to host node from node
Request adds the self-organizing subnet.
Then, in step s 304, host node can respond this and add request.
Now possibly, in step S305, all wireless channels may be scanned and sense at this moment from node（Including A
Class channel or B class channels）Common-channel interference indicated value.Pay attention to, host node and from node scan and sense or monitoring institute
There is wireless channel（Including A classes channel or B class channels）Cycle of common-channel interference indicated value may be different.
And in step S306, this is allowed to add it from node for example, by modes such as authentication region keys in host node
Afterwards, these common-channel interference indicated values that can be scanned and sensed from node are transmitted directly in the self-organizing subnet
Host node.So it can save winner in the case of the cycle that host node will also monitor common-channel interference indicated value without arrival
Point obtains as current as possible and more accurately common-channel interference indicated value.
Then, in step S307, host node will periodically（For example, with 10 seconds, 20 seconds etc. for the cycle）Monitoring is all
The common-channel interference indicated value of wireless channel.
Also, monitoring at the time of, in step S308, host node can notify in its self-organizing subnet it is all from
Node now suspends or reduced the communication activity on the wireless channel of the self-organizing subnet, up to predetermined amount of time（Such as 10 milli
Second etc.）.So do, host node can be prevented when monitoring the common-channel interference indicated value of multiple wireless channels, by it certainly
It is each from noise jamming caused by being communicated on the working channel of oneself between node in oneself self-organizing subnet,
So as to prevent following situation：Host node mistakenly monitors the common-channel interference indicated value of the working channel of oneself to be very big, from
And be mistakenly considered to need that the current operating channel of their own is switched into other channels, cause ceaselessly to switch channel.
Then,, can from node after the pause or reducing the predetermined amount of time past of communication activity in step S309
To recover its communication activity.
In step S310, host node can monitor common-channel interference indicated value in next monitoring cycle, and update
The table of its common-channel interference indicated value maintained.
That is, specifically, the host node can include two functions：（1）Host node initialization selection channel simultaneously connects
Added by other from node；（2）Host node monitoring, safeguard and update DCIT tables.
Above-mentioned function（1）Step 301,302,303,304,306 can be specifically included.Function（2）Step can be specifically included
Rapid 307,308,309,310.
Conveniently mention, host node can maintain the table of distributed common-channel interference indicated value（Distributed
Channel Interference Table, DCIT）, such as shown in table 1 below, that specify current on which specific channel
Common-channel interference indicated value（Co-channel Interference Indication Value, CIIV）Size（Table 1 below
In channel 1,6 and 11 be only exemplary rather than limiting）.
Table 1
| Channel | Ch#1 | Ch#6 | Ch#11 |
| CIIV | x | y | z |
Common-channel interference indicated value CIIV represents the size of the common-channel interference of the channel measured in real time.Channel is done altogether
Disturbing indicated value can calculate as follows：Calculate the common letter using each mobile device in a specific wireless channel
Road interference value；And each common-channel interference value calculated is weighted averagely, to obtain using corresponding weighted factor
The common-channel interference indicated value of the specific wireless channel.Common-channel interference value can be by using each of the same wireless channel
One or more of the real-time packet loss of individual mobile device, mean transit delay, wireless propagation path loss calculate.When
So, the common-channel interference indicated value of a wireless channel can also be calculated using other specification, this is known technology, herein

Fig. 3 B more intuitively describe being done in the common channel of initialization, monitoring and maintenance for the channel scheduling method shown in Fig. 3 A
Disturb indicated value and from node add in the case of schematic diagram of a scenario.
As shown in Figure 3 B, it is shown that a subnet（By taking self-organizing subnet 20-1 as an example）In host node monitoring and maintain altogether
Channel disturbance indicated value and the process added from node.During being somebody's turn to do, mobile node 102-1 is activated first（For example, opened
The dynamic or self-organizing subnetwork functionality etc. that is opened）, subsequent mobile node 102-1 monitors the common channel of all wireless channels in real time
Indicated value CIIV is disturbed, and is obtained such as the DCIT tables of the table 60 in Fig. 3 B.Based on this table 60, mobile node 102-1 can be with
Based on certain rule come to select a B classes channel or an A classes channel be its working channel, and subnet 20-1 is established, and should
Host nodes of the mobile node 102-1 as subnet 20-1.Thereafter, from node（Such as 103-1）It can add by host node 102-1
The subnet 20-1 of establishment.In addition, when adding subnet 20-1 from node 103-1, can be from from node 103-1 to host node 102-
The 1 the currently monitored DCIT tables with maintenance of report their own.Similarly, subnet 20-2 also has similar process.Then, host node 102-

DCIT tables.
Fig. 3 C are the example flow diagrams in the case where channel switches for showing the channel scheduling method according to Fig. 1.
Fig. 3 C flow charts can include the meaning of three aspects：1st, the behavior coordination based on perimeter key；2nd, base
The competition mechanism that channel switches between the subnet of premonitoring and random back-off；3rd, switch between asymmetrical two classes channel（A classes arrive
B classes and class B can follow different rules to class A）.
Specifically, B class channels are switched to from A class channels in response to a subnet（400）Requirement, can be walked as follows
Suddenly：
Step 401:The self-organizing subnet to be worked in a certain A classes channel is by certain external condition（That is, cut from A class channels
Change to the requirement of B class channels）Excite, so as to start a channel switching process.The external condition is probably：1st, there is big number in real time
According to or prioritized data require transmission；2nd, current operating channel is disturbed by severe；3rd, other.
Step 402:The common-channel interference instruction of all channels in the host node monitoring B class channel pools of the self-organizing subnet
Value CIIV.
Step 403:Host node judges the availability of B class channels by above monitoring result（Generally can be by judging it
Whether common-channel interference indicated value is less than the first predetermined threshold）.
Step 404:If B class channels can not be used, host node waits next monitoring common-channel interference indicated value CIIV
Cycle（Some periods for being used to receive and dispatch region keys can be postponed backward by current time）.That is, if described host node is true
Surely the preferential wireless channel that its common-channel interference indicated value is less than the first predetermined threshold is not present, then is carried out after the scheduled time
Determine whether there is the step of its common-channel interference indicated value is less than the preferential wireless channel of the first predetermined threshold.
Step 405:If available B class channels, then the working channel of the self-organizing subnet is switched to by host node preparation
The available B class channels（Alternatively, the timing of the switching is adjusted when receiving and dispatching region keys next time, because multiple existing
In the case of self-organizing subnet, it is arranged to synchronous at the time of sending respective region keys to each self-organizing subnet）.
Step 406:Step back at random.That is, since at the time of sending respective region keys to each self-organizing subnet, by
The host node delay respective different time delay for needing to carry out in the self-organizing subnet of channel switching is described more to be monitored
The step of common-channel interference indicated value of individual wireless channel.The step is used to avoid self-organizing to work in multiple A classes channels
Net is switched to a certain available B classes channel simultaneously.
Step 407:Monitoring confirms.In this step, host node can according to the common-channel interference indicated value monitored come
The step of deciding whether to carry out the channel switching again.The step is used to confirm the available B classes found in above-mentioned steps 405
Whether channel still can use, if it is not then can take steps in 406 it is random step back method, cancel cutting this time
Change, and wait possible switching next time.
Step 408:If B class channels can be used by confirming also presence in step S 407, host node is by the self-organizing subnet
Working channel is switched on the available B classes channel.
Specifically, A class channels are switched to from B class channels in response to a subnet（500）, following steps can be carried out：
Step 501:The self-organizing subnet to be worked in a certain B classes channel is by certain external condition（That is, cut from B class channels
Change to the requirement of A class channels）Excite, so as to start a channel switching process.The external condition may be：1st, real-time big data
（Or prioritized data）The end of transmission；2nd, timer is then；3rd, other.
Step 502:All channels in the host node monitoring A class channel pools of the self-organizing subnet.
Step 503:Host node selects in A class channel pools with minimum common-channel interference indicated value or its common-channel interference
Indicated value is less than the A class channels of the second predetermined threshold, and host node directly causes the self-organizing subnet to be switched to from B class channels
Worked on A class channels.
So, can be carried out in a distributed manner respectively by the host node of each self-organizing subnet under self-organizing network environment
From self-organizing subnet working channel switching action, be either switched to B classes channel still from B class channels from A class channels
A class channels are switched to, can more accurately and efficiently carry out the switching.

Fig. 3 D more intuitively illustrate a dynamic channel switching process.Initially, Fig. 3 D show one relatively
Stable subnet working condition, wherein subnet 1 are operated on channel 11, and subnet 2 and 5 works on channel 1, and subnet 3 and 4 works
On channel 6.Possibly, at a time, the subnet 1 being operated on B classes channel 11, which is excited, carries out channel switching（Referring to figure
3C process）, then the subnet 1 is monitored and selected, current common-channel interference is minimum or less than the second predetermined threshold in A class channel pools
A class channels, then switch to the A class channels.And after a B classes channel is available, the subnet to be worked on A class channels is then
Have an opportunity to be handed over, specifically need the requirement for being switched to B class channels be present（This step S401 that ask for an interview in Fig. 3 C and
Step S501 description）.While switching is needed, there may be multiple subnet competitions to be switched on a certain available B classes channel,
The method of this conflict avoidance is to step back and monitor at random affirmation mechanism（The step S406's that sees in Fig. 3 C and step S407 retouches
State）.
