We consider a joint sampling and scheduling problem for optimizing data freshness in multi-
source systems. Data freshness is measured by a non-decreasing penalty function of age of …

In this paper, we consider the problem of minimizing the age of information in a multi-source
system, where samples are taken from multiple sources and sent to a destination via a …

Discrete phase shifter of intelligent reflecting surface (IRS) generates phase quantization
error (QE) and degrades the receive performance at the receiver. To make an analysis of the …

In this paper (Part I and Part II), we investigate the optimal dynamic mode selection and
resource allocation to minimize the average end-to-end delay under a dropping probability …

In Part I of this paper (“Delay-Optimal Dynamic Mode Selection and Resource Allocation in
Device-to-Device Communications-Part I: Optimal Policy”), we investigated dynamic mode …

In this paper, we investigate the scheduling design of a mobile edge computing (MEC)
system, where active mobile devices with computation tasks randomly appear in a cell …

With the development of federated learning (FL), mobile devices (MDs) are able to train their
local models with private data and send them to a central server for aggregation, thereby …

Network function virtualization (NFV) has emerged as a new technology to reduce the cost of
hardware deployment. It is an architecture that using virtualized functions run on the virtual …

In a wireless powered communication network, where user equipments (UEs) harvest radio
frequency energy from an access point (AP) and send data to the AP, there exists the near …

In this paper, we investigate the power-delay tradeoff for the newly emerging wireless
powered communication networks, in which wireless powered devices (WPDs) harvest …
