In order to allow those skilled in the art to more fully understand and realize technical scheme, brief description this implementation
The operation principle of example.
Interface is closed wireless composite tester based on the communication protocol standards of IEEE 802.11 with multiple WLAN terminals in the air
After on connection, the MAC Address of each WLAN terminal is recorded.These WLAN terminals access machine by distributed competitive channel
System, i.e. CSMA/CA sends up data frame to wireless composite tester, while wireless composite tester participates in believing by agreement
Road is competed, and downlink data frame is sent to each WLAN terminal.During contention transmission opportunities, wireless composite tester with it is many
Individual WLAN terminal listens to channel idle within a DCF frame pitch times, each selects a random-backoff time to reduce
The possibility of transmitted data frame collision, i.e. distributed coordination function.
In order to describe the calculating process of handling capacity in detail, table 1 lists involved some passes in whole calculating process
Key index.
Table 1 calculates the key index of handling capacity：
| TSIFS | Frame pitch in short-term |
| TDIFS | DCF frame pitch |
| CWmin | Minimum keeps out of the way (Backoff) window time |
| TPHYhdr | Physical layer preamble code and the transmission time of header |
| TACK | The transmission time of ACK |
| TPSDU | One transmission time of PSDU units |
| τ | Radio signal propagation time delay |
| TRTS | RTS transmission times |
| TCTS | CTS transmission times |
| TBO | Keep out of the way (Backoff) time |
| RPHY | Physical layer transmission rate |
| LMSDU | The size (byte is unit) of MAC-PDU |
The communication protocol standards of IEEE 802.11 cover the MAC layer of media access control and the PHY layer of physics.Calculating
During the maximum throughput of WLAN terminal, it is necessary first to which the data frame for being sent to WLAN terminal or being received is analyzed, so as to carry out
Calculate.A protocol Data Unit is defined as the length of the transmission unit comprising PHY packet header expense in this layer in PHY layer, i.e.,
PPDU a, service data unit is defined as the size of PU Payload Unit in this layer, i.e. Payload, and this payload
It is the PPDU on upper strata.As shown in figure 4, Fig. 4 is the packet header expense structural representation of wireless network difference sublayer, which show to be measured
The structure of part package and expense during forwarding data frame.
As shown in Fig. 5 (a), Fig. 5 (a) is competition mechanism schematic diagram under CSMA/CA patterns, in addition on the basis of CSMA/CA,
WLAN terminal is also an option that the transmission means of RTS/CTS to avoid the collision caused by concealed nodes that Fig. 5 (b) is RTS/CTS
Competition mechanism schematic diagram under pattern, which depict the process of data frame transmission.
The throughput calculation methods of single data frame；
In order to calculate maximum throughput (bps), first by all of time overhead in each sublayer in the present invention
It is transformed into a common chronomere.In calculating process, by using similar service of the time-multiplexed mode to MAC layer
Data cell (SDU), i.e., MSDU is split, and then sets up effective maximum for payload and tells the amount of gulping down computation model：
Wherein τ is the time that signal is transmitted in wireless medium, LMSDUIt is that (i.e. valid data amount, unit is word to payload
Section), TPPDUIt is all time overheads required for the PPDU for transmitting this MSDU, including from intercepting idle channel DCF frame pitch
Start, competition obtains transmission opportunity in back off time, until the transmission transmission of whole data frame, and receive ACK confirmations.
TMSDUTime overhead include following particular content：
TPPDU=TDIFS+TBO+TPHYhdr+TPSDU+TSIFS+TACK (2)
Wherein TPHYhdrIt is the set time, and the transmission time T of PSDUPSDU=LPSDU/RPHYRemoved equal to PSDU length (bits)
With physical layer transmission rate RPHY。RPHYIt is varied from using different modulation-demodulation techniques, referring to table 1.If using
The transmission means of RTS/CTS, then TPPDUComputational methods it is as follows：
TPPDU=TDIFS+TBO+TRTS+TSIFS+TCTS+TSIFS
+TPJYhdr+TPSDU+TSIFS+TACK (3)
WLAN terminal may be operated with different speed, consensus standard in actual applications, thus can be produced not
With delay and expense, TPPDUExactly it is made up of these delay, expense and effective service data units.Control frame is such as
RTS, CTS, ACK, using minimum speed limit 1Mbps transmission using the speed of 6Mbps in 5GHz frequency ranges in 2.4GHz frequency ranges
Transmission, this is the backward compatibility row for 802.11 standards, is had to ensure in detection process, between different terminals preferable
Compatibility, this also complies with the demand of Practical Project.
When different WLAN terminals conflicts in test process without appearance, competition window (Contention
Window, CW) size exponential increasing will not be presented.Therefore, CW can be always to be equivalent to the big of minimum competition window by equivalent
Small (CWmin) only one of which WLAN terminal WLAN in because not competing conflict, CW always be in minimum value.Have
In the WLAN of multiple WLAN terminals, it is contemplated that back off time (TBO) uniformly random distribution is obeyed, calculating each
The T during handling capacity of WLAN terminal air interfaceBOValue can choose CWmin/2。
The throughput calculation methods of WLAN terminal；
In technical scheme disclosed by the invention, wireless composite tester can be according to the source MAC in data frame MAC layer header
Address and destination-mac address, calculate the up and descending data throughout of each WLAN terminal respectively.Actually measuring
Cheng Zhong, wireless composite tester have sent M to k-th WLAN terminalkIndividual data frame, the then downlink throughput capacity of this WLAN terminal
Can be calculated divided by total time overhead with the payload data amount transmitted altogether
Equally, the uplink air interface handling capacity of this WLAN terminal can also be calculated with formula above.Therefore, net
The data throughout of network can transform into the up and descending data throughout of each WLAN terminal by calculating.
Throughput calculation methods under non-ideal communication channel environment；
In non-ideal wireless transmission channel, some data frame may be lost or can not be correctly decoded by receiver, meeting
The data throughout of actual air interface is caused to decline.It is assumed that in measurement process, wireless composite tester is to k-th WLAN end
End have sent MkIndividual data frame, wherein the number of data frames of loss or mistake is Nk, then the downlink data of this WLAN terminal handle up
Amount can be expressed as：
Above-mentioned calculating neglects mistake or the data frame lost, but real time expense when payload data amount is counted
Mistake or the data frame transfer time lost is needed also to count.The handling capacity of the up-link of the WLAN terminal can also
Calculated with formula (5).
Although the foregoing describing specific embodiment of the invention, those skilled in the art should be appreciated that this
It is merely illustrative of, various changes or modifications can be made to present embodiment, without departing from principle of the invention and essence,
Protection scope of the present invention is only limited by the claims that follow.
