Embodiment Construction
[0032] refer to figure 1 , the realization of the present invention comprises the following steps:
[0033] Step 1, calculate the communication range of the control packet.
[0034] (1a) Define r as the communication radius of the single-input single-output SISO mode, and the bit error rate within the communication radius is less than 10 -5 , used to transmit data packets and control packets whose length does not exceed 512 bytes, expressed as:
[0035] r = v E S 49998.5 · N 0
[0036] where E s is the average power of the signal received at the unit distance of the transmitting node, v is the path loss index, N 0 is the average noise power;
[0037] (1b) According to the communication radius of single-input-single-output SISO mode, the constraint condition of control group commu...
