The authors consider a new approach to power control in decentralized wireless networks, termed Fractional Power Control (FPC). Transmission power is chosen as the current channel quality raised to an exponent - s, where s is a constant between 0 and 1. The choices s = 1 and s = 0 correspond to the familiar cases of channel inversion and constant power transmission, respectively. Choosing s ?? (0, 1) allows all intermediate policies between these two extremes to be evaluated, and they see that usually neither extreme is ideal.
