For ease of understanding, be that example is further explained explanation below in conjunction with accompanying drawing with several specific embodiments, and each embodiment does not constitute the qualification to the embodiment of the invention to the embodiment of the invention.
Embodiment one
The handling process of a kind of method of monitoring based on the node in the wireless network of protocol test that this embodiment proposes comprises following treatment step as shown in Figure 2:
The state that main controlled node in the wireless network disposes each node is stable state or mix, and the state of each node all is to change between stable state and mix.The mix of above-mentioned node is meant that all monitoring agencies monitor this node, and the monitoring agency does not filter the data such as message that this node sends.The stable state of above-mentioned node is meant specifies some monitoring agencies that this node is monitored, and other monitoring agency is provided with filtration to this node.
Node in the above-mentioned wireless network comprises: STA (Station, client) or AP (AccessPoint, WAP (wireless access point)), a STA and an AP are interrelated.
When initialization, the state that the main controlled node in the wireless network is provided with each node all is a mix.Then, main controlled node is acted on behalf of transmitting control commands to all monitorings, notify all monitoring agency all in the timeslice of a setting, the data such as message that certain node is sent are monitored simultaneously, and each monitoring agency calculates the RSSI of above-mentioned certain node.After above-mentioned timeslice finished, each monitoring agency calculated the average RSSI of above-mentioned certain node in above-mentioned timeslice, should report main controlled node by average RSSI, and main controlled node is acted on behalf of the RSSI that reports with each monitoring of each node correspondence and stored.
Receive the RSSI that the node AP1 that AG_1, AG_2, AG_3, AG_4 report is acted on behalf of in monitoring respectively such as, main controlled node, the RSSI information of the node AP1 correspondence of then storing in the main controlled node as shown in Figure 3.
Above-mentioned timeslice can for one long be time of 10 seconds, be the minimum time unit that monitoring system is operated.The advantage that each monitoring agency calculates the average RSSI in above-mentioned timeslice is to avoid because people or other mobile object mobile causes an instantaneous signal to noise ratio, and average signal-to-noise ratio more can embody monitoring agency's monitoring effect.
Main controlled node is according to the RSSI information of the node correspondence of storage, and predefined selective rule, judges whether and to select to specify the monitoring agency to the nodes for state conversion.Concrete judgment processing process is as follows:
When a STA node or AP node tanglewrack, whether this STA node of main controlled node judgement storage or each RSSI of AP node correspondence be greater than the threshold value of setting, if all RSSI are not more than above-mentioned threshold value, then determine not the state of above-mentioned STA node or AP node is changed.In next timeslice, continue to notify all monitoring agencies that above-mentioned STA node or AP node are monitored, and report its above-mentioned STA node that monitors or the RSSI of AP node.The threshold value of above-mentioned setting can be 6db, has only and satisfies the correctness that this condition could guarantee the reception of signal.
If the RSSI that STA node correspondence is arranged greater than above-mentioned threshold value, will screen greater than all RSSI of above-mentioned threshold value.Then, judge whether the monitoring agency of the above-mentioned RSSI correspondence that screens comprises the monitoring agency of the associated AP node correspondence of above-mentioned STA node,, then select the monitoring agency of the monitoring agency of above-mentioned AP node correspondence as above-mentioned STA node correspondence if comprise.Be that the STA node is when selecting monitoring to act on behalf of, AP node that will be related with the STA node as far as possible is in same monitoring agency, guarantee that single monitoring agency covers whole BSS (Base Station sub-System, base station sub-system) network as far as possible, for safety analysis lays the foundation; If do not comprise, then select the monitoring agency of the RSSI correspondence of the value maximum among the above-mentioned RSSI that screens to act on behalf of as the appointment monitoring of above-mentioned STA node correspondence.
If the RSSI that AP node correspondence is arranged greater than above-mentioned threshold value, will screen greater than all RSSI of above-mentioned threshold value.Then, select the monitoring agency of the RSSI correspondence of the value maximum among the above-mentioned RSSI that screens to act on behalf of as the appointment monitoring of above-mentioned AP node correspondence.
When a STA node or AP node designated behind the corresponding appointment monitoring agency, main controlled node carries the BSS ID of above-mentioned STA node or AP node and the appointment Monitoring and Controlling order of source address to the appointment monitoring agency transmission of this correspondence, the monitoring agency who notifies this correspondence joins the BSSID and the source address of above-mentioned STA node or AP node in the monitoring tabulation, and the data such as message of above-mentioned STA node or AP node are monitored.And, other monitoring agency sends and carries the BSSID of above-mentioned STA node or AP node and the filtration control command of source address to all, notify all other monitoring agency that the BSS ID and the source address of above-mentioned STA node or AP node are joined in the filter list, promptly stop the monitoring of all other monitoring agency, have only the effect of specifying monitoring agency monitoring to reach to this STA node or AP node.
Then, main controlled node is changed into stable state with the state of above-mentioned STA node or AP node.Repeat above-mentioned processing procedure, consistent with the state of all nodes is all changed into stable state.
Each specifies the monitoring agency all to manage a monitoring tabulation and filter list, monitor the BSS ID and the source address information of all nodes that comprise the monitoring of this monitoring agency needs in the tabulation, comprise the BSS ID and the source address information of all nodes of this monitoring agency needs filtration in the filter list.In fact the MAC Address of AP node is exactly its BSSID that organizes the BSS network, and the BSS ID of AP node is identical with source address, therefore, only need carry out BSS ID to the AP node and filter.And the BSS ID and the source address of STA node are inequality, need carry out BSS ID filtration and source address filtration respectively to the STA node.
Specify the monitoring agency behind the message that receives a node for one, obtain the BSS ID and the source address information of this message, if this source address information is included in the above-mentioned monitoring tabulation, then to above-mentioned message receive, processing such as detection.And this appointment monitoring agency also will calculate and send the RSSI of the node of above-mentioned message in real time, and the average RSSI in the timeslice is reported main controlled node.
If the BSS ID of above-mentioned message or source address information are included in the above-mentioned filter list, then needing to judge above-mentioned message is from STA node or AP node, for message from the STA node, if comprised the BSS ID and the source address of this STA node in the above-mentioned filter list simultaneously, then above-mentioned packet filtering fallen; For message,, then above-mentioned packet filtering is fallen if comprised the BSSID of this AP node in the above-mentioned filter list from the AP node.
Judge that above-mentioned message is as follows from the method for STA node or AP node: if the frame type of above-mentioned message is management frames and control frame, when the BSS of above-mentioned message ID identical with source address, judge that then above-mentioned message is from the AP node, otherwise, judge that above-mentioned message is from the STA node.If the frame type of above-mentioned message is a Frame, then judge that according to the sign in the From DS in the Frame and two territories of To DS above-mentioned message is from STA node or AP node.
Main controlled node checks according to the RSSI of the node of its monitoring of specifying the monitoring agency to report whether this appointment monitoring agency can satisfy minimum monitoring condition.If after the node motion, main controlled node is checked through the threshold value that the RSSI that specifies monitoring to act on behalf of the node of its monitoring that reports is not more than above-mentioned setting, perhaps, main controlled node does not receive specifies monitoring to act on behalf of the RSSI of the node of its monitoring that reports, and then the state of the node that above-mentioned appointment monitoring agency is monitored is changed into mix.
Then, main controlled node is acted on behalf of transmitting control commands to all monitorings, notifies all monitoring agencies all simultaneously above-mentioned node to be monitored in next timeslice, and reports the average RSSI of above-mentioned node in timeslice that monitors.The RSSI that main controlled node reports according to each node according to the agency's of the monitoring in the above-mentioned steps 12 system of selection, is that above-mentioned node selects to specify the monitoring agency again.
If the RSSI between the appointment monitoring agency node that report and its monitoring is greater than the threshold value of above-mentioned setting, then do not change the state (stable state) of above-mentioned node, even there is monitoring effect better to monitor the agency, do not change the appointment monitoring agency of this node yet.The purpose of doing like this is to reduce the frequent change that covers, and finds after tested, as long as can satisfy minimum monitoring condition, then is enough to guarantee to collect the correctness of data, so needn't change the monitoring agency.
