Each network node in described server coverage all may can report periphery detection messages to described server, if multiple network node reports to described server simultaneously, may cause congestion information, even may cause information dropout.Then preferably, described server respectively provides different appointment report cycles can to each network node in the coverage of described server, each network node can only report in the appointment report cycle of oneself, like this, described server distribute for each network node specify report cycle time can as far as possible by the report cycle of each network node between stagger, can effectively avoid congestion information phenomenon to occur.
In the embodiment of the present invention, each network node in the coverage of described server can send described detection messages to other network nodes in the coverage of self.That is, for described first network node, it can send described detection messages to the network node within the scope of described first network coverage, and meanwhile, described first network node also may can receive the described detection messages that other network nodes send.If described first network node receives the described detection messages that second network node sends, then equally can to response message described in described second network node reverts back.Wherein, described second network node is also any node in the coverage of described server, and described first network node is in the coverage of described second network node.
Preferably, in the embodiment of the present invention, can also comprise in described periphery detection messages and report temporal information, described in time when reporting temporal information to be used to indicate to report described periphery detection messages and/or be used to indicate report cycle corresponding to described periphery detection messages.
Refer to Fig. 2, based on same inventive concept, the embodiment of the present invention provides another kind of concealed nodes detection method, and the main flow of described method is as follows:
Step 201: server receives the periphery detection messages that network node reports; Wherein, described periphery detection messages is that network node is after sending the detection messages for detection of concealed node to other network nodes in coverage, generate according to the response message received and report, the information of other network nodes that the information of carrying the network node sending described detection messages in described periphery detection messages and the network node sending described detection messages detect.
Each network node in the coverage of described server all can report described periphery detection messages to described server, that is, described server may receive multiple periphery detection messages that multiple network node reports respectively.
Preferably, described server can be the periphery detection messages reported by mobile communications network reception network node.
Preferably, in the embodiment of the present invention, described network node can be STA, or can be also AP, and the present invention does not limit.
Such as, for the described first network node in the coverage of described server, described first network node can send described detection messages to other network nodes within the scope of described first network coverage, the network node receiving described detection messages can to response message described in described first network node reverts back, described first network node can generate described periphery detection messages, the information of the network node of replying described response message is added in described periphery detection messages, and the information of described first network node is also added in described periphery detection messages by described first network node, described periphery detection messages is sent to described server by described first network node afterwards.
Preferably, in the embodiment of the present invention, in the information of network node, at least can include the positional information of network node, nature, in described first network nodal information, also just at least can include the positional information of described first network node.
Step 202: the information of the network node that described server comprises according to described periphery detection messages, carries out concealed nodes detection.
Preferably, in the embodiment of the present invention, the information of the network node that described server comprises according to described periphery detection messages, carry out concealed nodes detection, specifically can comprise: for each periphery detection messages received, described server is according to the distributed intelligence of each network node preserved in advance, and the information of network node that periphery detection messages comprises, send periphery detection messages network node place network coverage in carry out concealed nodes detection; Or, for the periphery detection messages that each network node sends, the information of the network node that the periphery detection messages that described server reports according to each network node comprises, carries out concealed nodes detection respectively in the coverage of the network at described each network node place.
For the first situation, such as, can be previously stored with the distributed intelligence of each network node in the coverage of described server in described server, in the distributed intelligence of a network node, include the information of each network node in this network node coverage.
Or for described first network node, store the distributed intelligence of described first network node in described server, in the distributed intelligence of described first network node, include the information of each network node within the scope of described first network coverage.
Described first network node is after sending described detection messages to other network nodes within the scope of described first network coverage, each network node within the scope of ideal situation described first network coverage all should to response message described in described first network node reverts back, and the information of the network node of replying described response message will be added in described periphery detection messages by described first network node, should be ideally that the information of the all-network node within the scope of described first network coverage is added in described periphery detection messages.If there is the existence of concealed nodes, the described detection messages that described first network node sends then cannot be received with the network node of described first network node concealed nodes each other, naturally also can not to response message described in described first network node reverts back, the information of this network node also would not be added in described periphery detection messages by described first network node.
Described server is after the described periphery detection messages receiving the transmission of described first network node, can check successively the information of each network node that described periphery detection messages comprises, namely according to the distributed intelligence of the described first network node of this locality storage, determine whether the information of each network node that the distributed intelligence of described first network node comprises includes in described periphery detection messages.Such as, have the information of network node 1 to be included in the distributed intelligence of described first network node, but be not included in described periphery detection messages, then described server can determine described network node 1 and described first network node concealed nodes each other.
Or, with described first network node, second network node and the 3rd network node are example, the distributed intelligence of described first network node is stored in described server, the distributed intelligence of described second network node and the distributed intelligence of described 3rd network node, the information of each network node within the scope of described first network coverage is included in the distributed intelligence of described first network node, the information of each network node within the scope of described second network coverage is included in the distributed intelligence of described second network node, the information of each network node in described 3rd network node coverage is included in the distributed intelligence of described 3rd network node.
Such as, described first network node and described 3rd network node are all positioned at the coverage of described second network node, i.e. include the information of described first network node and the information of described second network node in the distributed intelligence of described second network node.So, if the periphery detection messages reported according to described first network node determines wherein not have the information of described 3rd network node, and/or, the periphery detection messages reported according to described 3rd network node determines wherein not have the information of described first network node, then can determine described first network node and described 3rd network node concealed nodes each other.In this case, described first network node can not be positioned at the coverage of described 3rd network node, or described first network node also can be positioned at the coverage of described 3rd network node.
Thisly determine that mode is very simple, without the need to the algorithm of complexity, also without the need to carrying out the improvement on hardware to arbitrary network node, feasibility is stronger.
Or in the embodiment of the present invention, described server side also can without the need to storing the distributed intelligence of each network node in the coverage of described server.The periphery detection messages that each network node that can receive in the coverage of described server because of described server reports, then described server can carry out according to each periphery detection messages the detection carrying out concealed nodes respectively in the coverage of each network node.
Such as, network node A and network node B concealed nodes each other, all do not comprise the information of the other side in the periphery detection messages that described network node A and described network node B reports to described server.But network node C to described server report periphery detection messages in have the information of the information of described network node A and described network node B, namely illustrate that described network node C is distributed in the coverage of described network node A and described network node B, described server can determine described network node A and described network node B concealed nodes each other according to the periphery detection messages that described network node C reports.
Or described server also can have other to determine the mode of concealed nodes, and the present invention does not limit.
Preferably, in the embodiment of the present invention, the information of the network node that described server comprises according to described periphery detection messages, carry out concealed nodes detection, can comprise: what described server at least comprised according to described periphery detection messages reports temporal information, determine whether report cycle corresponding to described periphery detection messages is specify report cycle; If report cycle corresponding to described periphery detection messages is described appointment report cycle, then the information of network node that comprises according to described periphery detection messages of described server, carries out concealed nodes detection.
Preferably, in the embodiment of the present invention, can also comprise in described periphery detection messages and report temporal information, described in time when reporting temporal information to be used to indicate to report described periphery detection messages and/or be used to indicate report cycle corresponding to described periphery detection messages.
For described first network node.Temporal information is reported described in can carrying in the described periphery detection messages that described first network node reports.If described in time when reporting temporal information to be used to indicate to report described periphery detection messages, time during described periphery detection messages is reported then, then described server side can store the appointment report cycle of promising described first network peer distribution, described server can report temporal information according to described and determine whether report cycle corresponding to described periphery detection messages is described appointment report cycle for the appointment report cycle of described first network peer distribution, if report cycle corresponding to described periphery detection messages is described appointment report cycle, the then described server information of network node that can comprise according to described periphery detection messages, carry out concealed nodes detection.
For described first network node.Temporal information is reported described in can carrying in the described periphery detection messages that described first network node reports.If described in report temporal information to be used to indicate report cycle corresponding to described periphery detection messages, then described first network node directly can according to described report temporal information to determine whether report cycle corresponding to described periphery detection messages is described appointment report cycle, if report cycle corresponding to described periphery detection messages is described appointment report cycle, then the described server information of network node that can comprise according to described periphery detection messages, carries out concealed nodes detection.
If described server is each network node define appointment report cycle, then each network node can only report periphery detection messages in the appointment report cycle of oneself, and can only report a periphery detection messages in an appointment report cycle.Such as, if the appointment report cycle of described first network node is 2s, and described first network node just reports described periphery detection messages when 3s, then described server can detect and determine that report cycle corresponding to described periphery detection messages is not described appointment report cycle, described server can abandon described periphery detection messages, specify report cycle to report because exceed, the result that may report is not accurate enough again.
