Below by enumerate that embodiment provides the application onePlanting micro power radio communication network address assignment method is elaborated.
An embodiment
Refer to Fig. 1, a kind of micro power radio communication network address that it shows the application provides is dividedA kind of flow chart of method of completing the square, can comprise the following steps:
Step S11: choose the Relay that relaying rank is minimum in each relaying rank being never selectedNot as current relaying rank.
In the present embodiment, in micropower wireless local network communication system comprise a Centroid andMultiple trunkings, wherein, trunking can be used as target device. Centroid is that trunking traffic is sent outPlay person.
Each trunking in micropower wireless local network in communication system is once being determined arbitrarilyIn trunking traffic, the relaying rank of each trunking is known definite. And, once true arbitrarilyIn fixed trunking traffic, the relaying rank of multiple trunkings can identically be that same relaying rank is passableCorresponding multiple trunkings. But the normal address of each trunking corresponding to each relaying rank is not respectivelyIdentical.
The trunking institute that can directly communicate with trunking traffic promoter in the present embodiment, is correspondingRelaying rank be minimum rank in all relaying ranks, can be directly and Centroid communicateThe corresponding relaying rank of trunking is minimum rank in all relaying ranks. Can be by direct and centerThe corresponding relaying rank of trunking that node communicates is set to 0 grade, can certainly be set toOther any one relaying ranks.
In the present embodiment, arbitrarily once in definite trunking traffic, directly and Centroid communicateThe corresponding relaying rank of trunking be 0 grade.
Taking the relaying rank that was not selected as 0,1,2 and 3 as example, to the relaying being never selectedIn rank, choose the relaying rank that relaying rank is minimum and describe as other process of current Relay, fromIn the relaying rank 0,1,2 and 3 not being selected, choose 0 grade of minimum relaying rank as current relayingRank. 1,2 and 3 become the relaying rank not being selected, the relaying rank 1 that was never selected,In choosing in 2 and 3,1 grade of minimum relaying rank is as current relaying rank. 2 and 3 become and are not selectedThe relaying rank of crossing, chooses minimum relaying rank 2 in the relaying rank 2 and 3 being never selected and doesFor current relaying rank. 3 become the relaying rank not being selected, using minimum relaying rank 3 asCurrent relaying rank.
Step S12: judge whether described current relaying rank is greater than directly and trunking traffic promoter carries outThe corresponding relaying rank of trunking of communication.
The trunking that if current relaying rank is not more than directly and trunking traffic promoter communicatesCorresponding relaying rank, execution step S13, if current relaying rank is greater than directly and trunking trafficThe corresponding relaying rank of trunking that promoter communicates, execution step S14.
Step S13: send broadcasting command to each unallocated network address corresponding to current relaying rankTrunking.
In the trunking institute that current relaying rank is not more than directly and trunking traffic promoter communicatesWhen corresponding relaying rank, Centroid directly sends broadcasting command to corresponding each of current relaying rankThe trunking of the unallocated network address.
Step S14: definite relaying rank that is less than current relaying rank one-level is intermediate relay rank.
Right in the trunking institute that current relaying rank is greater than directly and trunking traffic promoter communicatesAnswer relaying rank time, Centroid has been described and to be less than other each relaying rank of current Relay eachSelf-corresponding trunking carried out trunking traffic, Centroid be less than current Relay other eachThe relaying rank separately trunking of correspondence is carried out after trunking traffic, can records center node and each relayingThe communication path of trunking corresponding to rank.
Step S15: send broadcasting command to the address of distribution network corresponding to described intermediate relay rankTrunking, forwards described wide by the trunking of the address of distribution network corresponding to intermediate relay rankBroadcast the trunking of order to each unallocated network address corresponding to current relaying rank.
Due to the trunking of each unallocated network address corresponding to current relaying rank can only with centreThe trunking of the address of distribution network corresponding to relaying rank carries out direct communication, therefore needs in centreThe trunking of the address of distribution network corresponding to the rank that continues forwards broadcasting command to current relaying rank pairThe trunking of each unallocated network address of answering.
In the present embodiment, the distribution network corresponding with intermediate relay rank recording by CentroidThe communication path of the trunking of address, sends broadcasting command to distribution network corresponding to intermediate relay rankThe trunking of network address, then establishes by the relaying of the address of distribution network corresponding to intermediate relay rankThe standby trunking of broadcasting command to each unallocated network address corresponding to current relaying rank that forward.
Step S16: every the first Preset Time, judge whether to receive the described unallocated network addressThe normal address returned of trunking.
Centroid can turn with the trunking of the address of distribution network corresponding to intermediate relay rankWhile sending out broadcasting command, the corresponding time is initial time, every the first Preset Time, judges whether to connectReceive the normal address separately that the trunking of the unallocated network address returns. Certainly initial timeThe trunking that is not limited to the address of distribution network corresponding to above-mentioned intermediate relay rank forwards broadcastCorresponding time when order.
Every the first Preset Time, judge whether to receive described each unallocated network address inThe normal address that the trunking of the unallocated network address in the normal address that the equipment of continuing returns returnsTrunking by the address of distribution network corresponding to intermediate relay rank forwards, and is forwarded toCentroid.
Be not receive the normal address that the trunking of the unallocated network address returns in judged resultTime, execution step S17. Be that the trunking that receives the unallocated network address returns in judged resultNormal address time, execution step S18.
Step S17: and the non-judgement for the first time of current judgement, this judgement stopped.
Be not receive the standard that the trunking of the unallocated network address returns in the current result judging, and be currently judged as the first judgement when the address, can't stop this judgement, but at interval Preset TimeAfter again carry out once judgement, if judged result is still no, stop judging whether to receive unallocated networkThe normal address that the trunking of address returns.
Be not receive the standard that the trunking of the unallocated network address returns in the current result judgingWhen the address, and current be judged as non-for the first time judgement, just can stop judging whether to receive unallocated networkThe normal address that the trunking of address returns. To ensure really do not had trunking to return to study plotLocation, avoids in trunking returns to the process of normal address, just stopping judgement, and in causing not receivingThe situation of the normal address that the equipment of continuing returns occurs.
Step S18: the normal address that described trunking is returned is stored in the first list.
After the normal address of returning at the trunking that receives the unallocated network address, by trunkingNormal address be stored in the first list.
Step S19: choose corresponding any one in the normal address of storing in described the first list unallocatedThe trunking of the network address is as current trunking to be allocated.
In the present embodiment, in the first list, can store multiple normal addresses, each study plot of storageLocation is corresponding the trunking of unique unallocated network address separately.
The relaying of the unallocated network address corresponding to normal address that Centroid is stored from the first listIn equipment, choose the trunking of any one trunking as the current network address to be allocated.
Due to each normal address corresponding trunking of unique unallocated network address separately, because ofThis can be by choose the normal address that any one was not chosen from the first list, by this normal addressThe trunking of the corresponding unallocated network address is as current trunking to be allocated.
Step S110: distribute and send unique network address to described current trunking to be allocated, instituteThe size of stating the network address is less than the size of described normal address.
Current trunking to be allocated is being assigned with behind the network address, be converted to distribution network address inEquipment continues.
Step S111: whether judge in trunking corresponding to the normal address of storing in described the first listThere is the trunking of the unallocated network address.
If exist and do not divide in the judged result trunking that to be the normal address of storing in the first list correspondingThe trunking of distribution network address, returns to execution step S19. If judged result is to store in the first listTrunking corresponding to normal address in there is not the trunking of the unallocated network address, illustrate firstTrunking corresponding to normal address of storing in list has all been assigned with the network address, execution step S11.
When all relaying ranks were all selected, there is not the relaying rank not being selected,While there is not the relaying rank not being selected, just no longer return to each relaying that execution was never selectedIn rank, choose any one relaying rank as current this step of relaying rank.
In this application, redistribute by being respectively each trunking corresponding to each relaying rankThe network address, and the size of the network address is less than the size of each trunking normal address, makesThe network address of the trunking that packet contains same number, the size of the forward-path of its formationBe less than the size of the forward-path of normal address formation, the therefore complete time used contracting of transfer of dataShort, thus the efficiency of transmission of data and the real-time of communicating by letter with target device improved.
A kind of micro power radio communication address distribution method shown in Fig. 1 is except comprising each shown in Fig. 1Outside method step, can also comprise: confirm to receive receiving described current trunking to be allocatedWhen the feedback message of the described network address, the described network address is stored in the second list.
In the present embodiment, the second Preset Time also can be set, for waiting for that reception is current to be allocatedWhen trunking confirms that the time of the feedback message that has received the network address exceedes the second Preset Time, deleteThe normal address corresponding to trunking current to be allocated of storing in the first list.
In said method step, in micropower wireless local network in communication system, normal address pairThe byte length of answering is generally 6 bytes. Be 6 bytes at byte length corresponding to normal address,The byte length of the network address can be set in 2 bytes, 3 bytes, 4 bytes and 5 bytes arbitrarilyOne, can choose according to the number of the trunking in communication system in micropower wireless local networkUse the network address of respective byte length. For example,, in micropower wireless local network in communication systemThe number of trunking be not more than (216-1), when individual, can use byte length is the network of 2 bytesAddress. The number of the trunking in micropower wireless local network in communication system is not more than (224-1）When individual, can use byte length is the network address of 3 bytes. Logical in micropower wireless local networkThe number of the trunking in communication system is not more than (232-1), when individual, can use byte length is 4 wordsThe network address of joint. The number of the trunking in micropower wireless local network in communication system is littleIn (240-1), when individual, can use byte length is the network address of 5 bytes.
In micropower wireless local network, in communication system, the number of trunking is generally at 10000Left and right, much smaller than (248-1) individual, therefore there is no need to use byte length is the normal address of 6 bytes,Can, according to the concrete number of the trunking in communication system in micropower wireless local network, distribute phaseAnswer the network address of byte length, improved different communication systems and choose the flexibility of the network address, andOwing to using byte length to be less than the network address of byte length corresponding to normal address, improve transmission effectRate, with the real-time of communicating by letter with target device.
