METHOD FOR CONTROLLING POWER IN WIRELESS AD-HOC NETWORK

摘要

PURPOSE: A power control method in a wireless ad-hoc network is provided to eliminate inference on power control for sensing the channel occupation of adjacent nodes in a wireless network. CONSTITUTION: A node determines the initial transmission power of data subcarriers in a PDU(Protocol Data Unit) slot and an ACK(Acknowledgement) slot(S610). The node transmits the data subcarriers using the initial transmission power. The node transmits pilot subcarriers of the PDU slot and the ACK slot using the fixed power(S620). The node determines the transmission power of the data subcarriers in the PDU slot and the ACK slot by controlling closed loop power(S630). The node transmits the data subcarriers using transmission power determined in the frame. The node transmits the pilot subcarriers using the fixed power(S640).
