Description
Technical field
It is a kind of radio channel status information measuring method the present invention relates to wireless communication technology field.
Background technology
Existing wireless communication protocol, it is most of except the minority agreements such as ALOHA are using there is data at once in addition to sending mode
Agreement experienced channel condition information perception stage and data transmission phase during carrying out data transmission, all.
When there is data to be sent, node enters channel condition information perception stage.Data transfer shape in node sounding channel
State, judges the idle, busy of present channel（Data is activation success events or data transfer collision accident）Situation.Node leads to
The frame for receiving and being transmitted in channel is crossed, if content frame can be parsed successfully, judges to be successfully made a data transfer in channel；It is no
Then, judge to there occurs data transfer collision accident in channel.In the data is activation stage, after node judges that channel resource is available, hair
Send data and wait other side's response.
In existing protocol model analysis and prioritization scheme, for the measuring method of channel condition information, not effectively
Solve same node in same transmission cycle and caused measurement error is transmitted several times.In the discrepant network of channel access parameter
In, this measurement error can be bigger.
For support handling capacity weighting levels network, method proposed by the present invention, using the data of transmission success in channel
Frame information, counts the number of times of same node-node transmission, and then in channel condition information is calculated, successfully passed by constraining same node
Defeated number of times, so as to provide accurate channel condition information.
The content of the invention
In the network for supporting handling capacity weighting levels QoS demand, present invention analysis provides a kind of measurement wireless channel shape
The method of state information.In the present invention, using the average free slot time in channel twice between data transmission event as ginseng
Number, studies the measurement and calculating of channel condition information.
Same node is transmitted several times can cause channel condition information measurement error, and analytic statistics node of the present invention is successfully carried out
The number information of data transfer.The number of times of same node Successful transmissions is constrained in channel state information measurement, is node
Adjustment channel access parameter provides correct channel condition information.
The technical solution adopted by the present invention is, a kind of radio channel status information measuring method.In channel condition information sense
Know the stage, be mainly carried out in two steps, specifically include following steps.
The first step, information Perception process.Node is perceiving cycle PDetIt is interior（Amount to EDetIndividual time slot, after channel idle,
EDetProgressively it is decremented to " 0 ", completes a channel condition information perception）, obtain the letter of other node datas transmission in channel
Breath.The total degree E of other node Successful transmissions in node statistics channelSSuccessfully carry out data transmission with i-th sending node
Total degree ESi, and the total degree E collided in channelC。
Second step, information analysis calculating process.Data transmission event in node channel according to obtained by perception statistics
Information, the average free slot time n computing formula calculated in channel twice between data transmission event are as follows：
Wherein, βiIt is corresponding i-th sending node handling capacity weighting levels factor.Represent node
In the number of nodes for carrying out data transmission that perception is received.N is total number of nodes in network.
In above-mentioned calculating process, the data transmission event in node does not monitor channel does not carry out channel shape then
State information is calculated, using the parameter of current setting.
The features of the present invention and beneficial effect.
In the present invention, the event of other node datas transmission in channel condition information perception stage, node statistics channel
Information, analysis has carried out the node number of times of Successful transmissions, and then calculates channel shape according to corresponding handling capacity weight proportion relation
State information.The channel state information measurement not only goes for access parameter identical condition, it is also possible to adapt to access
In the different network environment of parameter.The present invention can be solved effectively in same transmission cycle, and same node is transmitted several times to channel
The error that status information measurement is caused, for the Adjusted Option of channel access parameter provides accurate channel condition information.

Specific embodiment
The network condition that the present invention is used mainly includes：Nodes have the different grades of service, i.e. handling capacity power
Weight grade.Throughput Class node high（NodeH）The node lower than Throughput Class（NodeL）Take more channel resources
Carry out data transmission.
In present embodiment, mainly consider that two kinds of grades of service of handling capacity weighting levels carry out patent content elaboration.This
Channel condition information computational methods are not limited to the quantity of the grade of service in invention.
Set the grade of service high（SH）（Throughput Class is high）With the low grade of service（SL）（Throughput Class is low）Ratio close
System is as follows：
As shown in above formula, in a transmission cycle, if data frame length is equal, work as NodeLA secondary data is have sent,
NodeHCarry outThe transmission of secondary data.
Assume that the handling capacity weighting levels of node can be identified by node address information in the present invention.The present invention
In, node have received the data frame of Successful transmissions in channel, parse received data frame information, obtain corresponding transmission source section
Dot address, the handling capacity weighting levels of sending node are may determine that according to address information.If collision is there occurs in channel, then only
Collision accident number of times need to be counted.Decision node Throughput Class information does not constrain use scope of the invention.
In the present invention, using data transmission event（Data transfer collision accident or data is activation success events）Between put down
Equal free timeslot is spaced as the metric parameter of channel condition information.
Based on formulaSetting, the present invention devises a kind of nothing
Line channel state information measurement, it is characterised in that：This programme is comprised the following steps.
The first step, node in channel condition information perception, in detecting period EDetIn the range of, by receiving channel in
The data transmission scenarios of other nodes, node judges that channel data transmits status information.If sending collision in channel, count
Collision accident number of times EC.If having successfully completed data transfer in channel, from data frame, extract and send source node address letter
Breath, the total degree E that i-th node of statistics successfully carries out data transmissionSi, and in EDetThe total successful data for inside receiving is passed
Defeated number of times ES。
Second step, when channel condition information perception terminates, node carries out channel condition information analytical calculation.Node root
According to data transmission event information in the channel for obtaining in the first step, the average free slot time number between event twice is calculated
Amount：
In above-mentioned calculating process, the data transmission event in node does not monitor channel does not carry out channel status letter then
Breath is calculated, using the parameter of current setting.
3rd step, node can adjust channel access parameter according to the average free slot time of analytical calculation.
The present invention be the foregoing is only than more typical embodiment, embodiments of the present invention and protection is not thereby limited
Scope, to those skilled in the art, should can appreciate that done by all utilization description of the invention and diagramatic content
Scheme obtained by equivalent and obvious change, should be included in protection scope of the present invention.
