Self-adaptive distributed power control for opportunistic QOS provision in wireless communication networks

Emerging wireless communication networks are required to provide data services which tolerate large variations of link quality. Such applications allow flexible power control procedures. In this paper, we approach the distributed power control problem from an automatic control point of view. A new framework for opportunistic power control is proposed, where the target quality of service at each link is determined by a linear quadratic regulator controller according to a given self-adaptive criterion. Stability and convergence of proposed framework are analytically guaranteed, while its performance is confronted with other algorithms through computer simulations.
