Joint Optimal Data Collection Scheduling and Time Allocation in Full-Duplex WP-IoT Networks
Ding Xu
Abstract
This article considers a full-duplex wireless powered Internet of Things (WP-IoT) network, supporting simultaneous wireless power transfer of a hybrid access point in the downlink and collected data transfer of devices in the uplink. Compared to existing works where the data collection process is mostly ignored, the problem of joint data collection scheduling and time allocation is investigated under two objectives, i.e., total throughput maximization subject to a total time constraint and total time minimization subject to minimum collected data constraints. For both objectives, the optimal solution is derived in closed-form. It is revealed that the proposed algorithms outperform various baselinealgorithms in existing literature.
