摘要：
A power control method and system of a wireless body area network and a transmitting node. The method comprises: after receiving a previous control packet, a transmitting node adjusts a transmission power level according to a transmission power level value carried in the previous control packet, determines a packet transmission time point according to a sample value from a local acceleration sensor, and sends a data packet to a receiving node at the packet transmission time point; the transmitting node receives a control packet fed back according to the data packet, the control packet carrying a next transmission power level value determined according to data reception strength of the data packet; and the transmitting node adjusts the transmission power level according to the transmission power level value carried in the control packet, determines a packet transmission time point according to a sampled value of the local acceleration sensor, and sends a next data packet to the receiving node at the packet tra
