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 …

Age of Information (AoI) is a metric often used to represent the freshness of the information
exchanged between a sensing source and a receiver. We consider a system where these …

We study status updating under two-way delay in a system consisting of a sampler, a sink,
and a controller residing at the sink. The controller drives the sampling process by sending …

Due to ease-of-deployment, autonomous control and low cost, unmanned aerial vehicles
(UAVs), as fixed aerial base stations, are increasingly being used as relays to collect time …

Age of information (AoI) and energy cost (EC) are two key metrics in real-time remote
monitoring systems. In this letter, we investigate the age-energy tradeoff for a short packet …

The upcoming Satellite Internet of Things (S-IoT) can provide status updates relaying for
ground user equipment (UE). However, the S-IoT cannot utilize the conventional hybrid …

We consider a multi-source relaying system where independent sources randomly generate
status update packets which are sent to the destination with the aid of a relay through …

We investigate Age of Information (AoI) in an Internet of Things (IoT) sensor network where a
single relay terminal connects multiple IoT sensors to their corresponding destination nodes …

We consider a multi-source relaying system where the sources independently and randomly
generate status update packets which are sent to the destination with the aid of a buffer …

This paper focuses on the timely delivery of status updates for a multi-relay assisted energy
harvesting (EH) Internet of Things system with short packet communications (SPC), where …
