Brief description of the drawings
Fig. 1 is structural representation of the invention；
Embodiment
In order that the technical problems to be solved by the invention, technical scheme and beneficial effect are more clearly understood, tie below
Drawings and Examples are closed, the present invention will be described in detail.It should be noted that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention, can realizes that the product of said function belongs to equivalent and improvement, include
Within protection scope of the present invention.Specific method is as follows：
Transmission system, including controller, data-analyzing machine, instruction dress are instructed the present invention relates to a kind of bicycle data network
Put, bicycle flow processing collects group, server group；
The present invention predicts bicycle data network running status in data-analyzing machine using heuristic adaptive algorithm.
Bicycle data network characteristic is global control and analyzed based on bicycle flow, the information that server group is collected in the present invention
Existing system history information, also there is system global information；Existing bicycle individual node information, the data for also having bicycle flow
The bicycle flow information formed with change.Server group is by collecting useful information come estimated following self adaptation bicycle data network
Network state, and the instruction set that possibility is instructed and optimized from these instructions is obtained by the to-be of prediction, because
This needs the instruction sending strategy for formulating instruction sending device more reasonably optimizing more wisdom.The voluntarily car data of the present invention
Position carries out the dynamic prediction of lapped transform data, root on single bicycle node, and in the entire network for network application
The frequency that bicycle node occurs in one's respective area is estimated according to data variation of the measurement bicycle node in the region of setting, in advance
Survey following bicycle flow distribution situation.Data-analyzing machine sets two bicycle flow parameters more accurate description bicycle flow and transported
Row state, has certain anticipation by the bicycle flow processing collection group for currently carrying forwarding, can be timely before blocking
Early warning, it is to avoid excessive bicycle vehicle is crowded into the region, and assesses the performance of bicycle node, and prediction one's respective area is voluntarily
The quantity of car, thresholding algorithm carries out shortest path selection as weights, if it exceeds respective threshold, then improve user voluntarily
Award value of the car away from this region.Data-analyzing machine predicts Shape Of Things To Come bicycle flow in the optional path set of one's respective area
Threshold value is assessed and selected there is provided selection algorithm, and bicycle node is estimated in the frequency that one's respective area occurs, when voluntarily
When excessive place occurs for car node, in order to which bicycle node recovers normal need transfer part carrying bicycle flow, manually doing
Before pre-, control device carries out evaluation valuation to the bicycle flow of the area operation.Control device forwards global information, and solely
It is vertical to safeguard global information copy, in order to describe bicycle node and link run time behaviour, and repeatedly weights as far as possible
Collect and computing module.If necessary to more global informations, cycle carnival dotted state, Link State during operation when such as running
And bicycle stream mode is transmitted during operation, server group and bicycle flow processing collection group need more complicated expansion module：It is right
In the correlation analysis of bicycle flow, it is analyzed can be from the input port of bicycle flow processing collection group, mac source address, MAC purposes
Address, ethernet type, IP source address, IP destination addresses, IP ports, TCP source port, TCP destination interfaces are analyzed, and are passed through
Bicycle flow processing collection cohort analysis, the bicycle that can be more enriched run time behaviour information in a network.In control
Device sets special bicycle flow analysis module, can obtain more information such as cycle carnival dot characteristics, amount of bandwidth, bicycle
The length of flow data, the frequency of occurrences of bicycle flow.The Expressive Features of bicycle flow are abundanter, and it is to the real-time pre- of bicycle flow
It is more accurate to survey.Much information can also be defined to read for controller, make localized network transmission stable by designing link metric, lead to
Tag processes are crossed to keep network bicycle flow stable:The factor of label is generally derived from driving node users root by message
According to set by current traffic environment.For example, car bicycle flow is more intensive in urban environment, now network signal intensity compared with
It is good, but because the presence of building, signal interference is relatively strong, and link is unstable between vehicle, suitably can manually increase vehicle, chooses
Network signal is strong and vehicle of vehicle approaching base station.Instruction sending device send instruction when must be provided with field, when its from
Driving nodal test transmits the holding time of frame into channel, just adjusts the network allocation vector of oneself and indicates channel in busy
The duration of state, bicycle flow processing collection group is after an instruction has been replied, other candidate relay bicycle node energy
Enough listen to the instruction, and judge whether to reply according to the field of the instruction is in same LAN.If so, now these
Bicycle node will stop their timer, and the value renewal in instruction, and R-T unit is switched to from reception mode
The time of sending method.If the relaying vector value that neighbours' vehicle is calculated is in identical interval, it means that they can be waited
Same time value replying instruction, so as to cause instruction to collide.
When server group gets the instruction that single bicycle node is sended over, the bicycle on single bicycle node
Stream process collection group will get No. ID of bicycle data network distribution automatically, and No. ID includes current No. ID and history ID,
Wherein, current No. ID be control device one of sequential selection idle sequence from ID ponds number, history ID is control device
No. ID of the message distribution for confirming to receive by server group for the last time；Control device is the single cycle carnival got
Information generates the single cycle carnival point identification included in certification message, certification message where label information point, Yi Jiwei on point
No. ID of label information distribution is right；Label information is reported to data-analyzing machine by control device, so that data-analyzing machine is judging
Current No. ID and history ID are differed, and history ID with data-analyzing machine is preserved No. ID it is identical when, return is single voluntarily
The response message of car node, wherein, No. ID of data-analyzing machine preservation is corresponding by data with single cycle carnival point identification
Current No. ID carried in the label information that analyzer the last time receives.
The beneficial benefit of the present invention：Estimated voluntarily according to data variation of the measurement bicycle node in the region of setting
The frequency that car node occurs in one's respective area, the following bicycle flow distribution situation of prediction.
