Abstract
The invention provides a method for realizing a wireless ad hoc network. The wireless ad hoc network is used for dividing in-cluster and inter-cluster control information to different areas in a wireless frame structure. Furthermore a control area and a data area which are specialized for each broadcast service are divided in the wireless frame structure. The method realizes overall scheduling on different types of services with different priorities through a specific frame structure. Furthermore through reserving a specialized control resource area and a data resource area for the high-priority broadcast service, service priority insurance is realized.

Need between receiving node through consultation or the mode of competition obtains the resource (bandwidth of transmission and holding of transmission data
Continuous duration etc.).In traditional network without center, which is applied to broadcasting service, such as PTT (language
Sound is broadcasted) time, resource contention or negotiation to be carried out with all neighbors, it is contemplated that can use of all neighbors
A large amount of control information that resource is difficult in the coordinating and unifying, and reservation process may occur touching in transmitting procedure
Hitting, therefore have and higher be likely to occur the situation that resource acquisition is failed, efficiency of transmission is relatively low.It addition, at present
The network without center of main flow there is no preferable scheduling mechanism to different types of business, in fact it could happen that preengage
The resource that takies of unicast service more discrete, cause broadcasting service to cannot be carried out the situation of reservation, also cannot be
Accommodate and under business premise as much as possible, ensure being smoothed out of high-priority service.
Additionally, in the most seen disclosed wireless ad hoc network systems based on TDMA, time all of
The division of gap is the most similar to the above, reserved protection interval between each time slot, it is to avoid internodal distance is different
The time slot collision caused with timing accuracy, but meanwhile, each time slot is while reservation protection is spaced
Also bring along the reduction of slot efficiency, have impact on the handling capacity of whole system further.

Node in same group indicates time slot across bunch PTT, within 2 jumping scopes not according to what business hop-diferented used
With the node of business jumping figure use across bunch PT instruction time slot in time domain orthogonal (jumping figure scope by system from
By arranging), the multiplexing in time domain of the node beyond 2 jumping scopes indicates time slot across bunch PTT, and identical services is jumped
What several node uses was identical indicates a time slot across bunch PTT.Scheduling of resource across cluster data broadcast instruction time slot
Strategy in like manner, more detailed process can be found in below with data and PTT district across a bunch PTT/ broadcast data
The description of the resource dispatching strategy of subframe.
Node public control zone across bunch route and control message area send and receive control information, including across
Bunch routing iinformation, across cluster node geographical location information, across a bunch resource reservation information.Disappear across bunch route and control
Breath district is made up of several subframes continuous or discrete in time domain in public control zone, and bunch route is at frequency domain
On be divided into several sub-bands, one constitutes one with a sub-band and controls resource across bunch controlling a subframe
Block, node randomly chooses the control Resource Block of use.
In bunch control zone by node broadcasts district, bunch in PTT service instruction district, bunch in route and control message
District forms, as shown in Figure 7.The present embodiment bunch in control zone use bunch in frequency-hopping mode, i.e. certain bunch
All nodes use identical frequency-hopping mode, become this bunch bunch in frequency-hopping mode, different bunches use difference
Bunch in frequency-hopping mode (in bunch, frequency-hopping mode selects is a narrowband slice using of bunch interior nodes, and not
It is specifically used subcarrier in frequency domain position).
Node bunch in control zone node broadcasts district send and receiving node broadcast message, the information carried is extremely
Include this node related information less.Node broadcasts district by bunch in several subframes of continuous print in time domain in control zone
Composition, node is according to from the son selected in bunch interior identity for sending own node broadcast message
Frame, the node broadcasts resource that in bunch, different nodes use is orthogonal in time domain.
Node bunch in control zone bunch in PTT service instruction district send and receive bunch in PTT service instruction
Information, bunch in data broadcast instruction information, in being respectively used to carry out bunch PTT service and bunch in data broadcast
The resource of business is seized.In bunch PTT service instruction district by bunch in discrete several in time domain in control zone
PTT instruction subframe composition in bunch；In in each bunch, PTT instruction subframe is divided into some bunches, PTT indicates time slot
With some bunches in data broadcast instruction time slot, frame structure is as shown in Figure 8.
For bunch in PTT indicate time slot, in each bunch, control zone comprises 3 bunches PTT indicate subframe,
Its resource dispatching strategy is: node according to self bunch in PTT service jumping figure select for send bunch in PTT
Instruction information bunch in PTT indicate time slot, the node of PTT service jumping figure in different bunches within 2 jumping scopes
Use bunch in PTT instruction time slot orthogonal in time domain, node multiplexing cluster in time domain beyond 2 jumping scopes
Interior PTT indicates time slot, in same cluster, the node of PTT service jumping figure uses identical bunch during PTT instruction
Gap.In bunch, the resource dispatching strategy of data broadcast instruction time slot is in like manner.
Node bunch in control zone bunch in route and control message area send and receive control information, including bunch
Interior routing iinformation, resource subscription information in bunch.Route in bunch and control message area by bunch in time domain in control zone
Upper continuous or discrete several subframes composition.It is being divided on frequency domain if routeing in bunch and controlling message area
Dry sub-band, a subframe constitutes one with a sub-band and controls Resource Block, and node randomly chooses use
Control Resource Block.
Node sends in data and PTT district and receives data and feedback information, and described feedback information is by node
State according to receiving data in data and PTT district constructs, and comprises retransmission feedback instruction or channel quality refers to
Mark or both combinations.Data are made up of several radio frames with PTT district, and each radio frames is by several bunches
Interior general data subframe, bunch in broadcast data subframe, across a bunch broadcast data subframe, bunch in PTT subframe and
Across a bunch PTT subframe composition, as it is shown in figure 9, each data and PTT district comprise 3 radio frames, each
Radio frames comprises 4 across a bunch PTT subframe.Data, with PTT district, use public frequency hopping mould across bunch business
Formula, frequency-hopping mode in business use bunch in bunch.Node according to public control zone and bunch in control zone by money
The data burst that the resource selection of acquisition uses is preengage and is seized in source.
Node bunch in send and receive non real-time or real-time unicast service in general data subframe, use and exist
The time-domain resource that in bunch, control zone is preengage by resource reservation relevant information.
Node bunch in send and receive in broadcast data subframe bunch in data broadcast service, bunch in PTT
PTT service in sending in subframe and receive bunch, is sending and is receiving across number of clusters in bunch broadcast data subframe
According to broadcasting service, sending and receiving across a bunch PTT service in bunch PTT subframe, use bunch in control
The time-domain resource of acquisition is seized by resource in district and public control zone.
For across a bunch PTT subframe, seizing acquisition time-domain resource in public control zone by resource, its resource
Scheduling strategy is: by across bunch PTT service be divided into 4 groups, each group takies each of data and PTT district
1 of radio frames across a bunch PTT subframe, take altogether 3 across a bunch PTT subframe, different groups use across
Bunch PTT subframe is orthogonal in time domain.Node in same group according to business hop-diferented use across a bunch PTT
Subframe, within 2 jumping scopes different business jumping figure node use across bunch PTT subframe in time domain orthogonal,
The multiplexing in time domain of node beyond 2 jumping scopes uses phase across a bunch PTT subframe, the node of identical services jumping figure
With across a bunch PTT subframe (if each data and PTT district comprise 3 radio frames, Mei Gewu in system
Line frame comprises 4k across a bunch PTT subframe, and k is more than 1, then system can be arranged to each group and takies each
The k of radio frames across a bunch PTT subframe, takies 3k within a bunch PTT subframe, 3k-1 jumping scope not altogether
With business jumping figure node use across bunch PTT subframe in time domain orthogonal).The most as shown in Figure 9:
(1) in even frame SF0, the PTT service source node of group 0 uses data and PTT district 0～3
Each district in group 0 in radio frames 0 send PTT service data message 1 (1 jumps) across bunch PTT subframe；
(2) PTT 2 hop node receives above 1 at SF0 and jumps PTT service data, in data and PTT district
In each district of 0～3, the group 0 in radio frames 1 forwards PTT service data message 1 (2 across bunch PTT subframe
Jump)；
(3) PTT 3 hop node receives above 2 at SF0 and jumps PTT service data, in data and PTT district
In each district of 0～3, the group 0 in radio frames 2 forwards PTT service data message 1 (3 across bunch PTT subframe
Jump)；
(4) in odd-numbered frame SF1 subsequently, the service source node of group 0 sends PTT service data message
2 (next PTT service data message bags), use data and radio frames in each district in PTT district 0～3
Group 0 in 0 is across a bunch PTT subframe (1 jumps)；Meanwhile, PTT 4 hop node receives step 3 at SF0
In 3 jump the PTT service data message 1 that PTT nodes forward, in data and the PTT district 0～3 of SF1
In each district, the group 0 in radio frames 0 forwards PTT service data message 1 (4 jump) across bunch PTT subframe.
Now 1 hop node and 4 hop nodes substantially employ identical time-domain resource, and transmission is different two
Packet, forms resource multiplex；In like manner, PTT2 hop node forwarding data packets 2, PTT 5 hop node turns
Send out data message 1, the time-domain resource that same use is identical.PTT3 jumps, and 6 hop nodes are by that analogy.
For across a bunch broadcast data subframe, its resource dispatching strategy is adjusted with the above-mentioned resource across bunch PTT subframe
Degree strategy is identical.
For bunch in PTT subframe, bunch in control zone seize acquisition time-domain resource by resource, its resource
Scheduling strategy is: node according to self bunch in PTT service jumping figure select bunch in PTT subframe, 2 jump models
Within enclosing in different bunches the node of PTT service jumping figure use bunch in PTT subframe orthogonal in time domain, 2
Node beyond jumping scope subframe in multiplexing cluster in time domain, in same cluster, the node of PTT service jumping figure makes
By subframe in identical bunch.In bunch, the resource dispatching strategy of data burst is in like manner.
When bunch in broadcast data subframe, across cluster data broadcast sub-frame, bunch in PTT subframe or across bunch PTT
Frame not by data broadcast in corresponding bunch, across cluster data broadcast, bunch in PTT or take across a bunch PTT service
Time, it is also possible to send in above subframe and receive non real-time or real-time unicast service.Use in a bunch internal control
The time-domain resource that district processed is preengage by resource reservation relevant information.
Each district in above frame structure of node (include synchronization zone, bunch service area, node broadcasts district, across
PTT instruction district in bunch/bunch, route in bunch/bunch and control the information area, data and PTT district) on transmit letter
Number time, for the frequency domain resource used during business data transmission, if before this at resource reservation or sound in seizing
The frequency domain resource position that bright corresponding business uses, should use the frequency domain resource stated before this；In the case of other,
Sending node can select the frequency domain resource used voluntarily.The frequency domain resource that node selects transmission to use (includes
Select the frequency-domain transmission resource that current transmission business/controls message uses, and select to be used for resource seize/
The frequency-domain transmission resource that in reservation, the business of statement will use) time, determine according to corresponding frequency-hopping mode and send out
Send the narrowband slice position that time point is corresponding, this narrowband slice selects the frequency domain that single transmission is specifically used
Resource.Wherein, when selecting specifically used frequency domain resource, frame structure supports that node selects whole arrowbands band
Width, i.e. uses full frequency band to be transmitted on the narrowband slice that frequency hopping skips to；Also support to use this narrowband slice
Fractional bandwidth.Can be by reusing the frequency that frequency hopping determines the fractional bandwidth of use in this narrowband slice
Position, territory, has an advantage in that, when the multiple nodes in communication range select for the resource transmitted in time domain shape
When becoming conflict, by the frequency hopping on frequency domain, it is possible to achieve multiple nodes use in same subframe or time slot
Different subcarrier in frequency domain, thus reduce the performance loss that conflict causes.
Above-mentioned node selects the frequency-hopping mode used by narrowband slice used on broadband by frequency hopping, and in choosing
Selected the frequency-hopping mode used by subcarrier used on fixed narrowband slice by frequency hopping, the two is separate
's.The strategy that frequency-hopping mode uses includes calculating pseudorandom according to node ID, distributing prewired according to node ID
The frequency pattern put, the whole network use identical frequency pattern but allocate frequency hopping start bit in advance according to node ID
Put.
The present embodiment will be used for the control information of different range (in bunch/bunch between) in the frame structure across point to not
Same region, and combine different bunches of interior nodes use resource isolation in time domain and/or frequency domain of frequency hopping realization,
Thus reduce the control information conflict in time domain of node transmission, add the interstitial content that MANET is supported.
Mark off the special control zone of all kinds of broadcasting service and data field in the frame structure, thus combine scheduling of resource plan
Slightly, special control zone completes resource reservation, the data broadcast service booking-mechanism of feedback can be avoided
The multinode of middle appearance produces the situation of a large amount of feedback informations, and the data broadcast service booking-mechanism of feedback-less
In the impact on neighbors that causes of the collision of the data service that is likely to occur and other business；Also avoid list
The business of broadcasting takies the most discrete reservation failure causing broadcasting service of time-domain resource.Additionally, by broadcast service
The data area make sure carries out multiplexing, maximizes power system capacity, and strengthens system flexibility.
Embodiment two
In public control zone in frame structure across a bunch PTT service instruction district, bunch in control zone bunch in
