Specific embodiment
The specific embodiment of the present invention is further described in detail below in conjunction with the accompanying drawings.
The present invention provides a kind of resource allocation methods and system for Integrated Electronic System on star, realize in high rail
Primary resource distribution in telecommunication satellite Integrated Electronic System, mainly includes in the realization flow and each star of resource allocation
The realization algorithm and processing mode of processing unit.
At this stage on star Integrated Electronic System main frame as shown in Figure 1, wherein Star Service administrative unit, platform synthesis industry
Business unit and load integrated service unit are integrated electronics subsystem units, by data/address bus on star (1553B) with other lists
Machine is attached, the interaction of the data that take remote measurement and instruction.In integrated electronics subsystem, it is extensive that unit has significant data preservation
Multiple function.But the memory space of unit is constrained to, too big data volume can not be stored；Meanwhile 1553B buses only provide
The message transmission rate of 1Mbps is can not meet the needs of distributed treatment and storage under such transmission rate.Follow-up
In design, the bus system of higher rate, such as SpaceWire buses etc. are employed.It is different with the bus-type framework of 1553B,
SpaceWire bus systems are the stellate framework there are router.To sum up, the reason of using game mode algorithm for design for：
1) developing direction of Integrated Electronic System is modularization, intelligence, therefore each on-board processing unit leads on following star
Frequently with the module design for having independent computing resource, distributed network structure is formd in terms of resource management, it is centralized
Resource Management Algorithm is poor to the adaptability of this kind of structure；
2) since the energy on star and computing resource are limited, repeated game and the use convergent scheme of iterative algorithm do not apply to
In the working environment of Integrated Electronic System on star, computing resource is wasted, while more communication overhead can be generated, occupied on star
The bandwidth of bus links.
Therefore, Fig. 2 on the star applied of the present invention integrated electronics framework it is schematically illustrate in, used similar
The framework of SpaceWire bus systems.As resource allocation moving party and participant, each on-board processing unit is in allocation flow
It is believed that with identical functional configuration；But it is proposed by the present invention sealed based on first valency (first price sealed-bid,
FPSB) the distributed allocation method of Auction Game Theory Theoretical Design is not limited to distributed network system (DNS), is having central manage-ment unit
System in, this method be likewise supplied with implement condition.
First, Collaboration computing represents that on-board processing unit provides the computing resource of itself and assists other on-board processing units
Process, the network architecture is as shown in Fig. 2, on-board processing unit is with the module or stand-alone device calculated with store function, under
The variable used in text does following definition：RsRepresent the resource that moving party occupies in cooperating process is participated in；RriIt represents to participate in
The resource that side occupies in cooperating process is participated in；WiRepresent the bus bandwidth proportion that communication process occupies；PriRepresent participant ginseng
With the consumption power proportion in cooperating process, QriRepresent the general power of participant；η represents the cooperation efficiency of participant；αiIt represents
Participant is bidded；kiRepresent the coefficient of bidding of participant.
For the cooperation efficiency of participant, calculated with formula 1：
I.e. initiator's occupancy resource is more, and the occupancy resource of participant is fewer, while cooperation efficiency occupies bus bar together
Wide and consumption power is inversely proportional.By above relationship, bidding for participant can occupy resource R with moving partysFor parameter list
Show：
Wherein ki is defined as greater than 1 coefficient, when ki is equal to 1, represents that participant ri can not be in Collaboration computing be participated in
Income is obtained, and is only capable of the occupancy resource overhead of covering participant.When ki is more than 1, the income that participant obtains is (ki-1)
Rri.Therefore for participant ri, there are the reserve prices of auctionIt is expressed as the form of formula 3：
Wherein a, b are the constant more than 0.The formula show for the occupied power of Collaboration computing it is higher, then participate in competing
The reserve price of valency is higher, and the increase of reserve price reduces the successful probability of participant auction.As participant riDuring auction success,
Income is
Therefore, the form that the occupancy resource of Collaboration computing can be expressed as：
Ci=Rs+αi 4
With reference to formula 2, can obtain：
It can be obtained from formula 5, CiIt is RsLinear function, therefore CiFor the R of given rangesThere are minimum value, simultaneously
It is continuous in the section, according to Kakutani fixed point theorems, there will necessarily be at least one Nash Equilibrium point.Therefore based on this
The participant of the algorithm of first valency sealed auction game can select the bidding strategies optimal to oneself interests, according to these strategies, ginseng
It bids with side to it after carrying out adaptive adjustment, system can reach a stable state.
The realization algorithm and processing mode of each on-board processing unit are described above, it below will be to resource allocation
Realize that flow is described in detail.
For the initiator of resource allocation task, operating process can be divided into following step according to shown in Fig. 3：
1) the cooperation efficiency η of task participant is set, the resource R occupied in cooperating process will be participated insPass through bus broadcast
Form be sent to other on-board processing units that can participate in the process；
2) in the latent period of setting, the feedback of task participant is obtained by bus communication, wherein containing participation
The available resource α of sidei；
3) after latent period, the available resource received is compared, the available resource of selection is minimum
And meet partner of the participant of task participant resource allocation requirements as Collaboration computing, this is sent to by bus communication
Participant confirmation message；
4) it establishes and connects with the participant, needed to carry out the data of Collaboration computing according to the resource ratio transmission of occupancy, be terminated
The wheel assigning process；
5) return to step 1).
For the task participant of resource allocation, operating process can be divided into following step according to shown in Fig. 3：
1) broadcast message is received, extracts the occupancy resource R of moving partys, calculate the bus that same task initiator communication occupies
Bandwidth proportion Wi, participate in the occupancy resource R of Collaboration computingriAnd participate in the power proportion P of cooperating process consumptionri；
2) reserve price of auction is calculatedIt is proposed a coefficient k of bidding for being higher than the reserve pricei, calculate and participate in Collaboration computing
Available resource αi, initiator is submitted to by way of bus communication；
If 3) do not receive the confirmation message of task initiator after latent period, be considered as this time bid unsuccessfully, to
Available resource is adjusted, return to step 1)；
If 4) confirmation message of task initiator is received in latent period, then it is assumed that this time is bidded success, establishes data
Link receives the data for needing to carry out Collaboration computing, terminates assigning process.
5) after the completion of Collaboration computing, return to step 1).
According to initiator set forth above and the realization flow of participant, you can establish the resource point of each on-board processing unit
Match, and the assigning process is independently completed by each on-board processing unit, the overall management without central manage-ment unit.
The step of carrying out resource allocation using the present invention is as follows：
1) the resource allocation requirements R in cooperating process as the on-board processing cell S of task initiator is calculateds, by resource
Distribution requirements RsOn-board processing unit (the r for n reception task for being used as task participant is sent to by bus broadcast1,…
