Step S110. local server, which is received, is directed to target by what the first movement node in mobile ad-hoc network was sent The video acquisition of video resource is requested.
When a certain mobile node of mobile ad-hoc network needs to watch a video content, network communication can be passed through A video acquisition is sent to local server to request, and the mobile node of request video is denoted as first movement in the present embodiment Node, while the video content of first movement node request is denoted as target video resource.Therefore, this step is first by this Ground server receives the video acquisition request being directed to for target video resource that first movement node is sent.Wherein, video obtains Taking request at least may include that nodal information, video information and/or temporal information etc. are various relevant to video request and transmission Essential information.For example, nodal information can be the network address of first movement node, video information can be target video resource Identification code in current video system, temporal information can be the time that first movement node sends video acquisition request Stamp.
Step S120. obtains the access frequency of target video resource, and judges that target video resource is according to access frequency No is hot point resource or non-hot resource.
Based on the video acquisition request received in step S110, can request to obtain first by parsing the video acquisition The video information for the target video resource that mobile node request obtains.Then, the visit of the available target video resource of this step It asks frequency, and category division is carried out to target video resource according to the access frequency, it can judge that the target video resource is No is hot point resource or non-hot resource.Wherein, hot point resource can be the relatively high current more prevalence of access frequency Video resource, rather than hot point resource is then the relatively low video resource of the relatively low current popular degree of access frequency.This In access frequency can be the video resource as obtained from the traffic monitoring to data access interface access data, in addition It can be and data are accessed by the video resource that any other approach such as network surveying or statistics obtains, the embodiment of the present invention is to this Do not do particular determination.
Step S130. if it is determined that target video resource be hot point resource, then by video acquisition request be sent to cloud service Device, to be capable of providing the second mobile node of target video resource for the distribution of first movement node by cloud server.
According to the judging result in step S130, if it is decided that the target video resource of first movement node request is Hot point resource, then in this step, the video acquisition request that first movement node is sent can be forwarded to by local server Cloud server, for first movement node selection and to distribute the second movement from mobile ad-hoc network by cloud server Node, the second mobile node can provide the target video resource of its request for first movement node, to realize video Resource-sharing.It for example may is that cloud takes from the second mobile node to the mode that first movement node provides target video resource Video acquisition request is sent to the second mobile node by business device, and then the second mobile node returns to a confirmation to first movement node Message, first movement node receives the interface channel that can establish after the confirmation message with the second mobile node, and then utilizes The interface channel obtains target video resource from the second mobile node.
Step S140. is if it is determined that target video resource is non-hot resource, then local server is first movement node point With the third mobile node for being capable of providing target video resource.
According to the judging result in step S130, if it is decided that the target video resource of first movement node request is Non-hot resource, then in this step, local server can distribute third mobile node for first movement node, third is moved Dynamic node can provide the target video resource of its request equally for first movement node, to realize that video resource is total It enjoys.In some other inventive embodiments, when determining target video resource is non-hot resource, when conditions permit It directly can also be that first movement node transmits corresponding video data by local server, the present invention does not do special limit to this It is fixed.

It is stored with the mobile node of target video resource in step S520. screening mobile ad-hoc network, and will be stored with The all or part of mobile node of target video resource is elected to be video and provides node to form video offer node set.
According to the video acquisition request received in step S510, this step can be screened in mobile ad-hoc network and be stored There is the mobile node of target video resource, while all or part of movable joint for being stored with target video resource can be clicked Make video and provides node to form video offer node set.In order to save use cost, cloud server can be to video The scale for providing node set is assessed and is regulated and controled.
Step S530. obtains each video that video is provided in node set respectively and provides the request of node processing video acquisition Expected time, and according to the expected time from video provide node set in screen a target video provide node.
After forming video offer node set by step S520, this step can provide the video each in node set The service ability that a video provides node is assessed, and the expected time for handling video acquisition request can be used as service ability A kind of evaluation index.This step obtains video respectively and provides the expected time of node processing video acquisition request, and can root Screening in node set is provided from video according to the expected time, and target video offer node is provided.Such as it can be by the expected time most Short video provides node and is elected to be target video offer node.
Step S540. will provide corresponding second mobile node of node with target video and distribute to first movement node, with Just target video resource is provided for first movement node by the second mobile node.
According to the selection result of step S530, it is corresponding that this step can provide the target video obtained with screening to node The second mobile node distribute to first movement node, to provide target video by the second mobile node for first movement node Resource.It for example may is that cloud server from the second mobile node to the mode that first movement node provides target video resource Video acquisition request is sent to the second mobile node, then the second mobile node returns to a confirmation to first movement node and disappears Breath, first movement node receive the interface channel that can establish after the confirmation message with the second mobile node, and then using should Interface channel obtains target video resource from the second mobile node.
It, can also be by first movement section after providing target video resource by the second mobile node for first movement node Point provides node as new video and is added into video offer node set.In general, the video newly increased provides node Possess relatively stable broadcast state, the stability in terms of providing video sharing service is also stronger.
In video resource sharing method provided in an embodiment of the present invention, cloud server can be based on the video received Acquisition request establishes video corresponding with target video resource and provides node set, and can be mentioned by cloud server to video It is safeguarded and is adjusted for the scale of node set.Local server is assisted to provide video sharing service by cloud server, While saving cloud server use cost, the scalability and Service Quality of video system can be promoted to a certain extent Amount.
On the basis of the above inventive embodiments, video resource sharing method can be comprising steps of adjustment video be provided Video in node set provides the quantity of node.Such as it can establish one and can safeguard the video resource towards service quality The video resource of dynamic equilibrium relation safeguards assessment models between supply and demand, according to the distribution and demand of video resource in network Situation, dynamic adjusts the use of cloud resource, to reduce cloud resource use cost.
As shown in fig. 6, in an alternative embodiment of the invention, adjustment video provides the video in node set and provides node Quantity may further include following steps:
Step S610. obtains the video that video is provided in node set and provides the Number dynamics change information of node.
Since the mobile node in mobile ad-hoc network can be added or exit at random according to the interests change of itself Video provides node set, therefore dynamic change can occur for the quantity of the video offer node in video offer node set.This Step can monitor video in real time and provide the scale state of node set, obtain wherein video and provide the Number dynamics variation of node Information.
Step S620. adjusts the video that video is provided in node set and provides node according to Number dynamics change information Quantity.
When video, which provides node, exits video offer node set, video provides available video resource in node set Quantity will be reduced, so that the video of cloud server maintenance provides each video offer node needs in node set and undertakes More request message processing loads and data transfer loads.Therefore, in order to maintain the service quality of video sharing service, this step Suddenly it can adjust the video that video is provided in node set according to the Number dynamics change information got in step S610 and provide The quantity of node.For example, providing the departure rate of node greater than video offer node when video provides the video in node set When increment rate, the video that cloud server can expand maintenance provides node set scale, to keep the confession of target video resource It should be with the balance of demand.
In addition to the adjustment mode in the above inventive embodiments, adjustment video provides the video in node set and provides node Quantity, can also include: according to video provide node set in each video provide node processing video acquisition request Expected time, adjustment video provide the video in node set and provide the quantity of node.
When the departure rate that video provides the video offer node in node set, which is less than video, provides the increment rate of node, The scale that video provides node set will constantly expand, and not only result in a degree of resource redundancy, and will increase cloud Use cost of the server in terms of maintenance video provides node set.In this case, cloud server can be according to each A video provides the video that an expected time for processing video acquisition request is provided video in node set that picks and provides node Quantity be adjusted.For example, the length of can provide each video to node desirably time is ranked up, it would be desirable to when Between longer video node be provided remove video node set is provided, so that the scale that video provides node set is maintained one In a suitable range.
When the increment rate that video provides the departure rate of the video offer node in node set and video provides node is basic Equal, the quantity that video provides node will also keep relative stability.But the if movable joint of request target video resource When point quantity is continuously increased and each video is caused to provide node due to loading increase and generating request message processing delay, cloud The video that server can expand maintenance provides the scale of node set, increases video and provides the quantity of node, to maintain to regard The service quality of frequency shared service.
As shown in fig. 7, in an alternative embodiment of the invention, adjustment video provides the video in node set and provides node Quantity may comprise steps of:
Step S710. obtains video and provides the history of each video offer node processing video acquisition request in node set Handle information.
The available video of cloud server provides each video in node set and provides the request of node processing video acquisition Real-time status, thus can also to each video provide node history processing information record, such as may include view Frequency provides the number of requests for the video acquisition request that node receives within the unit time, handles the average time of request message, passes The average time etc. of defeated video data.
Step S720. handles the quantity for the video offer node that information adjustment video is provided in node set according to history.
Information is handled based on the history got in step S710, this step can provide video the view in node set The quantity that frequency provides node adjusts.For example, can be calculated according to the history processing information that a certain video provides node The video provides the request message handling rate and request message arrival rate of node, if request message handling rate is lower than request message Arrival rate, then cloud server can be moved out video and mention it is considered that the processing capacity of video offer node is lower For node set.And after its processing capacity improves, cloud server can provide the video to node again and be added to maintenance Video is provided in node set.The mode of this dynamic adjustment can reduce view while guaranteeing video sharing service quality Frequency provides the scale of node set, to reduce the use cost of cloud server.
Based on above method embodiment, the embodiment of the present invention also provides a kind of video resource sharing means, for being movement Mobile node in self-organizing network provides video resource shared service, which can be set up in cloud clothes Business device one end.As shown in figure 8, the video resource sharing means 800 in the embodiment of the present invention mainly may include: that cloud receives mould Block 810, the first screening module 820, the second screening module 830 and node distribution module 840.Wherein, 810 quilt of cloud receiving module Cloud server is configured to receive by the first movement node transmission in mobile ad-hoc network and by local server forwarding For the video acquisition request of target video resource；First screening module 820 is configured as depositing in screening mobile ad-hoc network The mobile node of target video resource is contained, and all or part of mobile node for being stored with target video resource is elected to be view Frequency provides node and provides node set to form a video；Second screening module 830 is configured to obtain video offer section Each video in point set provides the expected time of node processing video acquisition request, and is provided according to the expected time from video A target video is screened in node set, and node is provided；Node distribution module 840 is configured as that node will be provided with target video Corresponding second mobile node distributes to first movement node, to provide target by the second mobile node for first movement node Video resource.

In addition, although being referred to several modules or unit for acting the equipment executed in the above detailed description, But it is this divide it is not enforceable.In fact, embodiment according to the present invention, two or more above-described modules Either the feature and function of unit can embody in a module or unit.Conversely, an above-described module or The feature and function of person's unit can be to be embodied by multiple modules or unit with further division.
Video sharing method provided in an embodiment of the present invention is described in detail below with reference to a concrete application scene.
As shown in figure 9, when video system provides Video service for the mobile node 920 in mobile ad-hoc network 910, Cloud server 930 can assist in local server 940 to manage popular hot point resource, intensively be requested on a large scale with handling, Video server pressure can not only be effectively relieved, and available bandwidth can be provided in time for requesting node, to promote view The scalability and service quality of display system.Video sharing method and video sharing means based on the embodiment of the present invention, Initially set up the video resource of dynamic equilibrium relation between the video resource supply and demand that one can safeguard towards service quality Safeguard assessment models, according to the distribution of video resource in network and demand status, dynamic adjusts the use of cloud resource, to drop Low clouds end resource use cost；And the dynamic dispatching machine of a video resource supplier is further provided on this basis System is video request person's dynamic allocation and schedule video supplier according to the load of video vendor itself, to be effectively reduced Load between video search delay and balance video supplier.Specifically, the application scenarios mainly include following three aspect Content:
1. the design of local server
Local server stores the initial video resource provided for mobile node.When a mobile node a needs to watch When one video content, video request is sent to local server, video request message includes requesting node information, request view Frequency ID and request time stamp.After local server receives the request message of node a, by the video request Message Record of node a In local, then a becomes DBMS member.So, local server storage and maintenance is made of list each DBMS member, in list The information of each DBMS member of record includes requesting node information, the video ID of request and the timestamp of request.Work as local After server receives the request message of node a, local server selects one and a system is being added from local system members list Time interval of uniting is the smallest and stores video vendor of the node b of the video resource of request as a.When lesser addition system Between interval can ensure that a and b keep relative synchronization on broadcast point, promote the stability of logical connection between the two.In addition, being Load and enhancing video sharing efficiency, video server between balance video supplier also need to consider video vendor Service ability.When the service ability of video vendor relatively strong (possessing higher bandwidth, storage, calculating and cruising ability), depending on Frequency supplier will not frequently cut off and the connection between video request person since own load is excessively high.When video request person a is received After the confirmation message that video vendor b is returned, a establishes the connection between b, and obtains video data from b, to complete Video request process.If any node logs off in video system, need to send exit message to local server.It is local Server after receiving exit message, delete from local system members list by the node that will move out system.
The number of nodes increase of addition system will increase the maintenance load of server, can not undertake reality so as to cause server When maintenance system member condition, to solve this problem, local server is accessed by cloud server come maintenance request high frequency The node state of video content, thus alleviate the pressure of video server, the scalability of lifting system.When DBMS member requests When one popular video resource, the request message of these nodes can be forwarded to cloud server, and cloud server is its point It with suitable video vendor or is directly video request person's transmitting video data.
2. the Scale Revenue Ratio of cloud server maintenance node
The money of the video resource for being stored in DBMS member local and scheduling DBMS member is safeguarded by lease cloud resource Source can generate high cost, and in order to more economic use cloud resource, the scale of cloud server maintenance system member is answered The holding is suitably horizontal.Due to the dynamic change of user interest cause request resource constantly change and mobile node storage provide The dynamic in source substitutes, and cloud server needs the supply and demand situation maintenance system member according to video resource.Assuming that system The collection of the middle all mobile nodes for having cached some video v is combined into S, then set S just provides node collection for the video of video v It closes.Video provides the video offer node in node set and is receiving after the request message of cloud server forwarding, to Video request person returns to confirmation message and is its transmitting video data, each video provide node for request message queue according to Frist come,frist serve successively handles request message.
If handling rate is requested to be greater than request arriving rate, video vendor can quickly handle request message and be video request Person's transmitting video data.Conversely, then showing to need to handle more request message due to video vendor, generate at request message Reason delay, to increase the waiting delay of video request person.Since DBMS member can be random according to the interests change of itself Video is logged off and requested, causes number of elements in S to generate dynamic change, therefore: if element subtracts in S within the unit time Few quantity is greater than the increased quantity of element, then the scale that cloud server should expand element in the S of being safeguarded (increases need Safeguard DBMS member's quantity of storage video v).When DBMS member logs off, they are in the video resource being locally stored It will be deleted, the available video resource quantity in system will be reduced, so that the candidate video of cloud server maintenance provides Person needs to undertake more request messages processing load and data transfer loads, therefore, when storage video v DBMS member from When opening increment rate of the rate greater than DBMS member, cloud server should expand DBMS member's scale of maintenance, to keep video v's The balance of supply and demand.When DBMS member's quantity of storage video v keeps stabilization, but DBMS member's quantity of request video v When increasing and candidate video supplier being caused to load increase generation request message processing delay, cloud server should expand maintenance DBMS member's scale.When video request person receives video data from video vendor, video request person will be received Video data is cached to local, then just becoming a candidate video vendor, i.e., number of elements can be with video in S at this time The increase of requestor and increase.When cloud server needs expansion to newly increase the maintenance scale of element in S due to these Candidate video supplier possesses relatively stable broadcast state, should be preferentially added in S.If cloud server is safeguarded Video vendor be difficult to carry more processing message and transmit number load and cloud server does not increase the maintenance of element in S Scale, then cloud server is directly to video request person's transmitting video data.
3. the scheduling mechanism of video vendor
The service ability of video vendor is depended on for video request person's distribution and schedule video supplier.Candidate is regarded For the service ability of frequency supplier, each candidate video supplier is calculated using local request message processing queue length Handle the expected time of a request message and transmitting video data.This expected time can be considered as candidate video supplier Service ability.The request message processing expected time is shorter, illustrates that the service ability of candidate video supplier is stronger.When cloud takes After business device receives request message, suitable candidate video can be selected to mention for video request person from the candidate video supplier of maintenance Donor.This is because the continuation of the journey of each mobile device, bandwidth, calculating and storage capacity are limited, cloud server not only needs root Request message is forwarded according to candidate video supplier's service ability, and to balance the load between candidate video supplier.
Cloud server will remove remaining bandwidth from candidate video supplier's list of maintenance and be unable to satisfy video request Node or request message handling rate that person needs are lower than the node of request message arrival rate.If removed candidate video mentions The bandwidth and processing capacity of donor are restored again, then it can be added to the video vendor column of maintenance by cloud server again In table.When cloud server has received a request message, cloud server selects clothes from the video vendor list of maintenance The maximum element of business ability is as video vendor.At this point, cloud server mentions the video that video request person is added to maintenance (video request person is considered as to new video vendor) in donor list.During handling each video request message, depending on The quantity for the video request message that frequency supplier b record receives and processing time complete to the video data of video request person After transmission, b will record total data transmission period, and send a message to cloud server, include in the message of transmission: when unit The number of requests that interior b is received handles the average time of request message, the average time etc. of transmitting video data.Cloud service Device calculates and updates the service ability of b using these information, and continues as video request person using updated result and distribute clothes The strong video vendor of business ability.
