We summarize recent contributions in the broad area of age of information (AoI). In
particular, we describe the current state of the art in the design and optimization of low …

We consider a wireless network with a base station serving multiple traffic streams to
different destinations. Packets from each stream arrive to the base station according to a …

We consider an Internet of Things (IoT) monitoring system, in which an IoT device monitors a
physical process and transmits randomly generated status updates to its associated access …

In applications of remote sensing, estimation, and control, timely communication is critical
but not always ensured by high-rate communication. This work proposes decentralized age …

Information updates in multihop networks such as Internet of Things (IoT) and intelligent
transportation systems have received significant recent attention. In this paper, we minimize …

In this article, we consider the average age minimization problem where a central entity
schedules M users among the N available users for transmission over unreliable channels. It …

In this paper, we examine the potentials of Non-Orthogonal Multiple Access (NOMA),
currently rivaling Orthogonal Multiple Access (OMA) in 3rd Generation Partnership Project …

Internet of Things (IoT) has emerged as one of the key features of the next-generation
wireless networks, where timely delivery of status update packets is essential for many real …

We consider a setting where multiple active sources send real-time updates over a single-
hop wireless broadcast network to a monitoring station. Our goal is to design a scheduling …

A two-hop energy harvesting communication network is considered, in which measurement
updates are transmitted by a source to a destination through an intermediate relay. Updates …
