In this paper, a brief overview of the power control problem will be presented along with different directions in power control design. In addition, a new approach to power control design inspired from control theory will be introduced. In this approach, linear quadratic control will be utilized to determine the transmission power of each node in the network. The system states will represent the signal quality and the error between the signal-to-interference level and the desired target. The necessary modifications to the IEEE 802.11 MAC layer to incorporate the proposed power control algorithm will be described.
