B1, relay A use common modulation code to receive and demodulation control sequence, and are signal interference ratio by resolving the signal interference ratio obtaining receiving control sequence; According to the value receiving class items in control sequence, judge that whether receive control sequence is that application sends sequence, if the control sequence received sends sequence for application, then enter step B2, otherwise relay A re-executes step B1;
B2, judge the address of this relay A and apply for that whether the destination address that sends in sequence is identical, if not identical, then relay A judges that route is congested, after the postponement Δ t time, re-executes step B1; Otherwise the identification code of taking out in application transmission sequence the website that starts replaces the identification code of this relay A;
B3, the signal interference ratio threshold value that the reception control sequence signal interference ratio obtained in step B1 and sensor network are preset compared, if signal interference ratio < signal interference ratio threshold value, then relay A enters step B1; Otherwise relay A calculates surplus signal interference ratio, surplus signal interference ratio=signal interference ratio-signal interference ratio threshold value, according to the value PT that step B1 receives through-put power item in control sequence, determine that the through-put power of this relay A is PT-f (surplus signal interference ratio);
B4, the station transmission power P T-f (surplus signal interference ratio) determined with step B3 send website that application sends sequence and send and allow to send sequence in step B1;
After the website sending application transmission sequence in B5, step B1 receives and allows to send sequence, use the identification code of this website and allow to send the through-put power that in sequence, through-put power item is determined, sensing data is sent to relay A, after relay A receives sensing data, the website sending application transmission sequence in step B1 sends and successfully receives response sequence.
6. a method as claimed in claim 5, the originating address item of the permission transmission sequence of described step B4 inserts the address of relay A, destination address item is inserted in step B1 and is sent the address that application sends the website of sequence, and through-put power item inserts the station transmission performance number PT-f (surplus signal interference ratio) that step B3 determines.
