Minimum Length Scheduling for Discrete Rate Based Full Duplex Wireless Powered Communication Networks
Authors:
Publisher and Date:(Springer, 2019)In this study, we consider a wireless powered communication network where multiple users with radio frequency energy harvesting capabilities communicate to a hybrid energy and information access point in full duplex mode. We characterize an optimization framework for minimum length scheduling to determine the optimal rate adaptation and transmission scheduling subject to energy causality and traffic demand constraints of the users considering discrete-rate transmission model. We first formulate ...

Minimum Length Scheduling for Full Duplex Time-Critical Wireless Powered Communication Networks
Authors:
Publisher and Date:(IEEE, 2020)Radio frequency (RF) energy harvesting is key in attaining perpetual lifetime for time-critical wireless powered communication networks (WPCNs) due to full control on energy transfer, far field region, small and low-cost circuitry. In this paper, we propose a novel minimum length scheduling problem to determine the optimal power control, time allocation and schedule subject to data, energy causality and maximum transmit power constraints in a full-duplex WPCN. We first formulate the problem as a ...

Optimal On-Off Transmission Schemes for Full Duplex Wireless Powered Communication Networks
Authors:
Publisher and Date:(IEEE, 2020)In this paper, we consider a full duplex wireless powered communication network where multiple users with radio frequency energy harvesting capability communicate to an energy broadcasting hybrid access point. We investigate the minimum length scheduling and sum throughput maximization problems considering on-off transmission scheme in which users either transmit at a constant power or remain silent. For minimum length scheduling problem, we propose a polynomial-time optimal scheduling algorithm. ...

Scheduling and Relay Selection for Full-Duplex Wireless Powered Cooperative Communication Networks
Authors:
Publisher and Date:(Institute of Electrical and Electronics Engineers Inc., 2020)In this manuscript, we consider a full-duplex wireless powered cooperative communication system where the users communicate with a hybrid access point through relays. We formulate an optimization problem with the objective to minimize the total transmission time through user scheduling and relay selection while considering the traffic demand, energy causality and initial battery levels of the users. The formulated optimization problem is a mixed integer non-linear programming problem, hence difficult ...

Throughput Maximization for Full Duplex Wireless Powered Communication Networks
Authors:
Publisher and Date:(Institute of Electrical and Electronics Engineers Inc., 2020)In this paper, we consider a full duplex wireless powered communication network where multiple users with RF energy harvesting capabilities communicate to a hybrid energy and information access point. An optimization framework is proposed with the objective of maximizing the sum throughput of the users subject to energy causality and maximum transmit power constraints considering a realistic energy harvesting model incorporating initial battery levels of the users. The joint optimization of power ...

Throughput maximization in discrete rate based full duplex wireless powered communication networks
Authors:
Publisher and Date:(John Wıley & Sons Ltd, 2020)In this study, we consider a discrete rate full-duplex wireless powered communication network. We characterize a novel optimization framework for sum throughput maximization to determine the rate adaptation and transmission schedule subject to energy causality and user transmit power. We first formulate the problem as a mixed integer nonlinear programming problem, which is hard to solve for a global optimum in polynomial-time. Then, we investigate the characteristics of the solution and propose a ...
