Abstract: PURPOSE: A power control and allocation method in a wireless mesh network is provided to control transmission power to transmit data to a gateway and the number of users who are connected to each AP(Access Point). CONSTITUTION: A first constraint condition is calculated from each link capacity and each user channel capacity of a wireless mesh network. A second constraint condition is calculates from the number of users who access each AP. Transmission power for each AP and the number of users of each AP are determined in order to optimize the necessary transmission power for configuring backhaul in the wireless mesh network based on the first and the second constraint conditions(S520,S530).
