Information and communication technology (ICT) has been an essential part of modern
society. However, the current communication systems are not sufficient to meet the demands …

Unlike center users, edge users are unable to achieve reliable data transmission due to
severe path loss, and the resulting frequent retransmissions not only bring additional energy …

With the advent of 5G technology, the notion of latency got a prominent role in wireless
connectivity, serving as a proxy term for addressing the requirements for real-time …

Age of information (AoI) is gaining attention as a valuable performance metric for many IoT
systems, in which a large number of devices report time-stamped updates to a central …

In vehicular edge computing networks, edge service caching has emerged as a promising
technology that supports delay sensitive applications. When the vehicles pass the coverage …

One of the critical use cases for prospective fifth generation (5G) cellular systems is the
delivery of the state of the remote systems to the control center. Such services are relevant …

This paper considers a real-time status update system in which an energy harvesting (EH)-
powered transmitter node observes some physical process, and sends its sensed …

We study a general setting of gossip networks in which a source node forwards its
measurements (in the form of status updates) about some observed physical process to a …

This paper considers a multi-source updating system in which a transmitter node powered
by energy harvesting (EH) sends status updates about multiple sources of information to a …

In this paper, we investigate the age minimization problem for a two-hop relay system, under
a resource constraint on the average number of forwarding operations at the relay. We first …
