Existing power and rate control methods for wireless communication networks aim to maximize the system capacity and the network throughput, and attempt to increase the quality-of-service (QoS), but cannot guarantee the QoS. This paper presents a new power and rate control method for wireless communication networks, which is based on the priority of QoS, so the QoS can be guaranteed. A dual closed-loop...
In this work, we focus on minimizing the overall network energy consumption problem under delay-constrained: N different packets from N time varying channels must be transmitted by a hard deadline of T slots. Each transmitter determines how much power to transmit with, during each time slot based on the current channel quality and the number of un transmitted bits, with the objective of minimizing...
This paper considers power and rate control for wireless networks with time-varying delays, uncertainties and input constraints. A robust delay-dependent model predictive power and rate control method is presented, and the state feedback control law is obtained by solving an optimization problem. Simulation results verify the effectiveness of the proposed method.
This paper considers power and rate control for wireless networks with time-varying delay. A delay-dependent robust power and rate control algorithm is presented via the H∞ control approach. Simulation result shows that the proposed algorithm has good performance.
This paper is concerned with adaptive fault-tolerant power and rate control for wireless networks. Based on the new joint power and rate control model, an adaptive fault-tolerant controller via state feedback is presented for transmitter fault compensations. The adaptive H∞ performance of the closed-loop system is analyzed based on the linear matrix inequality (LMI) Simulation results are given to...
Power control is an important requirement for code-division multiple access (CDMA) mobile wireless networks. Especially, it can effectively overcome the near-far problem. However, almost all existing power control algorithms assume that the time delay is known and fixed. While the time delay is often unknown or time varying under actual environments. This paper investigates power control of CDMA mobile...
This paper investigates power control of CDMA wireless networked systems with random transmission time delays in both downlink and uplink wireless communication channels. To deal with the random time delays, a novel power control algorithm is presented based on the modified generalized predictive control (M-GPC). Different from the conventional generalized predictive control (GPC) in which only the...
This paper investigates power control of code-division multiple access (CDMA) systems with random transmission time delay and uncertainty in communication channels. To deal with the random time delay and reduce the effects of uncertainty due to channel fading and interference, an adaptive power control algorithm is presented based on predictive control approach. Simulation results are given to demonstrate...
