A distributed automatic control solution for power allocation of wireless communication networks is proposed in this paper. The objectif is to combine the best features of both conventional and opportunistic power control, namely, fairness and opportunism on the QoS provision. In a first step, the Distributed Power Control (DPC) problem is formulated as a Linear Quadratic Regulator (LQR) problem....
Next generation of wireless broadband network such as WiMAX MMR networks and LTE Advanced support high quality multimedia services with high data transmission rate. Most of the current broadband operates at high frequency and thus has limited transmission range. Multi-hop relaying technology is seen as an efficient solution that could enhance coverage and improves system capacity. However, overall...
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...
This paper proposes a distributed power control framework for wireless communication networks that is able to provide a flexible QoS with the introduction of a dynamic target QoS into a conventional (fixed) target tracking power control algorithm. The target QoS of individual terminals is automatically updated according to a given performance criterion. The distributed power control is formulated...
