N2 - When considering mobile communication systems we see that for services which can tolerate delay do not need to maintain a minimum signal-to- interference ratio (SIR). In fact, to achieve maximum throughput transmission power should be increased when the interference level is low, and information transmission rate adjusted accordingly through adaptive modulation and coding. This approach is called opportunistic communications. In this paper, we introduce an opportunistic power control algorithm, which exploits the channel fluctuation of wireless channels. The algorithm is distributed and is proven to converge to a unique fixed point. Simulation results show that a significant increase in system capacity can be achieved, when compared with the traditional target tracking approach. © 2004 IEEE
