Description of drawings:
Fig. 1 is the skeleton diagram of a wireless self-organizing and self-adaptive system, A equipment possesses the performance higher than B equipment among the figure, "/" back is the equipment that is set to listening state for the equipment of N, for the equipment of Y is the equipment that is in passive listening state, for the equipment of X is online equipment.
Fig. 2 is that wired information of equipment and other equipment is connected, and D equipment can be a computer, PDA, digital camera, MP3 or the like, and A equipment is equipment of the present invention, and data-transformation facility is provided.
Embodiment:
Execution mode one:
With Fig. 1 is example, can realize system as follows:
Online equipment in the system is A1, A2, A3, A0, B1, B3, and equipment B 2 is in passive listening state, and device A 4, B0 are operated in listening state.
System initial state, it may be first system's appointed information circulation that any one equipment among A1, A2, A3, A0, B1, B2, the B3 sends, pay special attention to equipment B 2, though it may be online equipment at the beginning, but owing to device A 1, A3, A0 have superiority than its performance, position, equipment B 2 can only be in passive listening state; Equipment B 3 is because it can be as the specific position of the bridge of device A 0 and A2, though its performance is not strong, but still be online equipment, analytical equipment B1 again is because it is in the edge, can only keep in touch with device A 1, also owing to the relation of position, it is left online equipment, equipment B 0, A4, owing to himself do not ask online, so,, can not be set to online equipment regardless of its equipment performance, position.
Among Fig. 1,6 online device A 1, A2, A3, A0, B1, B3 are arranged, we suppose, the maximum online number of system is set to 5, situation in Fig. 1, A3 will be entered the pressure listening state, and reason is the position of it and A1, A0, here information can be passed between A1, the A0, and the information A 3 of device A 1 or A0 can both be obtained.
Therefore, we can describe online appointed condition like this: the existence of online equipment in the system, always make this system trend form point-to-point serial network and (or) make that the scope of the network coverage is the wideest.
Under above-mentioned network configuration, the circulation of broadcast message can followingly realize:
One, supposes that these online equipment have an equipment to have only a system access channel, device A 1 needs information of broadcasting, usually A1 waiting system appointed information arrives, after the arrival, at first send the broadcast message of certain-length, online equipment is transmitted successively by the parameter of the last system appointed information circular list, device A sends next broadcast packet after 1 counting period, after so being recycled to the holding time that distributes broadcast message or regulation, device A 1 is sent the cyclical information of system's appointed information, this time off-the-air; Other online equipment send with reference to this execution.
Two, suppose that these online equipment all possess the another one passage, device A 1 needs information of broadcasting, and A1 waiting system appointed information arrives usually, after the arrival, and check system circulation message at first, discovery channel is occupied, just fills in outstanding message; Discovery channel is unoccupied, just indicate occupied information, send system's appointed information, after each this information of audiomonitor uppick, monitor this channel,, can transmit at once to online equipment requirements nearby if audiomonitor can not be monitored this channel, device A 1 was gone on the air in definite time, own declaration off-the-air or overtime end in system's appointed information.
Three, audiomonitor does not possess broadcast right, but passive monitoring can send broadcast message by the way by unique agency of its appointment.
Under above-mentioned network configuration, information is transmitted and can be achieved as follows:
One, the forwarding of broadcast message only occurs between unique agency of passive monitoring and its appointment, and when information arrives when acting on behalf of, to act on behalf of broadcast message the same with this in subsequent operation.
Two, point-to-point forwarding.
If unidirectional transmission information just with information encryption, is online equipment if post a letter, just directly broadcast away with single frames, if audiomonitor, just the agency by its appointment broadcasts away with single frames.After designated equipment received, the acknowledgement information of first single frames was only received in broadcasting or by plaintext of agency's broadcasting or encrypt receipt, equipment itself (containing online equipment) or act on behalf of and can continue to broadcast remaining information.This information transmit and common broadcasting different, be recorded information source position not, certainly, the receipt of single frames information also is like this.Because this single frames information is shorter, fast, generally can't realize the radio position finding radio directional bearing operation, to sending, particularly recipient's location privacy is higher.
If two-way communication, just need at first to determine route: if at the online communication between devices that can not directly arrive, route is just determined by the online equipment oneself of initiating; If at audiomonitor (no matter be initiatively or passive) and online equipment, and the initiator is audiomonitor, and route is just definite by the initiator; In addition, all need to act on behalf of online equipment and send path finding broadcasting, after the communication object of being sought is answered, send acknowledgement frame, comprise routing iinformation and authorization information in the acknowledgement frame, just route is determined by called equipment.After the checking of checking frame is passed through, just along this path communication.If there is channel more than needed in this path, just set up " dedicated channel " passage, when finishing, communication tears chain open, if do not have, just transmit by system information carrying channel.
The whole cryptographic calculations of this verification process wherein all adopt public key algorithm, and with following authentication stipulations:
R1: the equipment of initiating to communicate by letter sends the path finding frame, and represent the DID of initiating equipment and target device with plaintext in the frame, and produce an identifying code and additional information at random, and with the password encryption of arranging before this identifying code and the additional information use;
R2: target device obtains solicited message, and the password to decipher with arranging before is verified sign indicating number, and produce a signcode at random, with this signcode with before the password encryption of agreement, and with this signcode encrypted authentication sign indicating number, insert routing iinformation then, send route and checking Echo Frame;
R3: initiate at first decrypt communication sign indicating number of communication equipment, and utilize this sign indicating number to solve identifying code more expressly, compare,, then by authentication, do not meet, then authentification failure if meet.
In order to realize above-mentioned system configuration, networking function is broadcasted and information is transmitted, and must could realize by a locking equipment.Equipment in this example can be described as follows:
Above-mentioned network configuration, function, can be solidificated in the form of agreement in the systems soft ware of CPU, carry out different instruction bodies by the message of receiving with the operation that needs, each system equipment is all being safeguarded several forms (data structure): comprise online DID table, corresponding PID table, information arrives table, and message pick-up table etc. can wait with BIT or EYTE and represent different states.Particularly, a kind of equipment of realizing this system can be such:
RF module: can comprise 100MHz, 200MHz, 300MHz, 400MHz, 900MHz, 2.4GHz numerous frequencies etc. all or part of frequency range, and RF module can comprise one or more independent send and (or) unit that receives, pass through interface, CPU can be controlled channel, the power of emission, the parameters such as mode of modulation easily, simultaneously, also can obtain the information that specified channel receives from this module by digital interface, signals such as the information strength that receives, this RF module may possess one or more high performance antennas.On the physical structure, this RF module directly is connected with antenna, be connected with CPU and power subsystem by data cable, certainly, this RF module also can with central processing unit on same printed circuit board, be connected with antenna by radio frequency cable, at power hour, also antenna can be installed on the printed circuit board, perhaps directly antenna directly be made on the printed circuit board.
Voice unit: on the contrary voice unit with voice signal be converted to digital signal or, and carry out (for example CVSD, in waiting, several or whole G.711, G.722, G.729, G.729A, H.323 such as compressed encoding decoding, can adopt DSP, perhaps special chip is realized), perhaps directly be connected with a FM/AM passage, and without digital processing, broadcast and listen to voice messaging in the mode of plain code, and by central processing unit controls receive, the channel of emission, modulation system, compression/decompression format.This voice unit also can comprise one or more audio frequency input or (with) output interface.
Operating unit: form by various buttons, knob, be connected with CPU, accept operational order by cable.
Data interface unit: by standard interface such as RS232/485/422, USB, Ethernet etc. and other equipment wired connections, as shown in Figure 2.
CPU: comprise one or more single-chip microcomputers or also comprise more high performance CPU, program and data storage, the above-mentioned various establishments and the agreement of operational system, the programs of encrypt/decrypt etc. are all carried out according to program by this unit.
Equipment just can be realized the said system function by the combination of above-mentioned several modules.
Execution mode two:
For clearer understanding with implement content of the present invention, we will go up example and simplify, and obtain following network configuration:
Suppose that the online maximum device number of our system is set to one, but multiple devices are arranged in the system.
Obviously, no matter process is how, always last equipment that function is the most powerful is online equipment (if this equipment is set to line model), other equipment or be in passive listening state, or be in listening state.
A kind of typical application model that Here it is, guide or interpreter occupy an leading position, if with commentary recording, send to each equipment in the system, just each visitor or tourist in specific place by broadcast mode.Simultaneously, if the visitor have any problem can be separately and guide or interpreter link up, also can chat voluntarily between the visitor.
Certainly, if there are two tourist groups all to use this equipment, their distance is far away during beginning, does not have what problem, when a group from another the group through out-of-date, will go wrong.The imperative operation intervention can solve the problem that this situation runs into, and through consultation, the channel of transformation system just can easily solve.
In this example, signal strength detection can be used for producing the prompt tone of falling behind, and can notify the visitor on the one hand, also can notify the guide on the other hand.
This example is not brought into play the advantage that area coverage was transmitted, increased to the information of self-organizing system.But this system has utilized the performance of broadcasting greatly, and the maximized broadcast resource that utilized is applied in the solution of this class problem, is very effective and hommization.
Realizing the equipment of this system, no matter software still is that hardware all can be simpler than execution mode one, is the subclass of mode one, and for example equipment can followingly design:
Visitor's machine: possess two system access channels and one and put question to or exchange channel, directly make the FM mode.Just adopt 100MHz or 900MHz, adopt the one chip, perhaps also have a speech chip,, wait where necessary and play by Single-chip Controlling for prompt tone.Can directly make an earplug in shape or be contained on the cap, provide a push-to-talk to be used for getting in touch with online equipment (guide).
Guide machine: and visitor's machine relatively possesses bigger transmitting power, higher receiving sensitivity and more senior PID sign.
The circulation of system's appointed information shows by the characteristic frequency of FM, only needs a kind of state of expression, and this design can be done equipment price extremely low, is convenient to promote.
Certainly, if the price permission also can realize with the equipment of mode one.
Obviously, see on the whole that mode two has realized a subclass of the present invention with knockout price.
Execution mode three:
We follow the applied environment of mode two, still another form of coming illustrative system in guide and visitor's mode.
Suppose that there are 40 passengers in this tourist group, between free active stage, wandered away, be distributed in various places, the passenger who has can't uppick guide's set broadcasting, but the forwarding by with the personnel of group can reach, and just needs to transmit broadcasted content or transmits point-to-point information.
Suppose that all devices all is arranged on line model at the beginning, because being provided with online equipment maximum number is 1, and cause the passive monitoring of other all devices, at this moment, this numerical value is set to 41, so, all equipment can enter into system's appointed information circulation, certainly, and by transmitting, aggregate information also can be communicated on the equipment that can not directly send to originally, points out this passenger to rejoin one's unit.
The realization of its equipment need not have been given unnecessary details.
In this example, the advantage that has represented some self-organizing networks intuitively.
Execution mode four:
We follow the applied environment of mode two, three, still another form of coming illustrative system in guide and visitor's mode.
Suppose that there are 40 passengers in this tourist group, between free active stage, wandered away, be distributed in various places, the passenger who has can't uppick guide's set broadcasting, by forwarding, can not reach with the personnel of group, but, forwarding by other guides is to reach, and just needs to transmit point-to-point information by other guides, broadcasts in the system that this guide and another one guide is formed.
Suppose at the beginning because the phase mutual interference has been adjusted channel between this guide and that guide, not at same channel.This guide is made as listening state with oneself rapidly, and system access channel is set to those guides' channel, sends a broadcast request, and the channel of designated broadcast, and the passenger who wanders away like this can receive the broadcasting of rejoining one's unit.
Certainly, on agreement, more than such way can be given the team member for change, but the method that this example is realized is succinct.
The realization of its equipment has not been given unnecessary details.
In this example, the advantage that has represented other self-organizing networks intuitively.
Execution mode five:
In above-mentioned execution mode two, three, four, all lay particular emphasis on the application of voice, change a little, just can be used in 110 wireless systems, the traffic police, patrol police's communication system is if re-use the circulation of digital enciphering system appointed information, add the networking authentication function, obviously military purposes be can be used for, by reasonably being set in ray mode and listen mode, and DID, PID number revised dynamically, and system's appointed information circulation etc., can obtain the application of many significant individual soldier's communications.Force the application of intervening measure, be easy to obtain communication mechanism flexibly, ensure the communication task of the complexity under the war condition.
Equipment during this class is used, the communication of equipment room is carried out in the encryption of the agreement that just can use DSP to handle to communicate by letter and voice, data with the frequency hopping mode.Multiple function is provided in the device software, comprises the standby communication protocol of some covers and some communication deception means.
Execution mode six:
The communication system that this invention provides except that voice are provided, can also provide data service, should, data service is an emphasis, and voice are a kind of auxiliary.Fig. 2 is that equipment such as computer are with the situation of this invention equipment as a peripheral hardware.
Several execution modes in back are easy for what narrate, are not very complete embodiments, but in conjunction with execution mode one and other contents, can understand fully and realize.
Though the present invention has exemplified many examples, be can't limit eventually, by change a little, just can change the embodiment that other, but its marrow can not become.
