Abstract Space–air–ground–sea integrated (SAGSI) networks are envisioned to connect
satellite, aerial, ground, and sea networks to provide connectivity everywhere and all the …

Intelligent Vehicle Systems (IVSs) devote to integrating the data sensing, processing, and
transmission in the Vehicle to Everything (V2X) scenarios, where the Unnamed Aircraft …

In this paper, we investigate non-orthogonal multiple access (NOMA) based average age of
information (AoI) in LEO satellite-terrestrial integrated networks. Two-user NOMA scheme is …

In this paper, we study the age-oriented hybrid automatic repeat request (HARQ) protocol
design in space-air-ground integrated networks (SAGINs) scenarios. A real-time …

The timeless and efficient vehicle data transmission are the two common requirements for
the Internet of Vehicles (IoV), especially the Unnamed Aircraft Vehicle (UAV)-aided …

Space-Air-Ground Integrated Network (SAGIN) as an efficient newly integration network
could provide more comprehensive network services to meet the multifarious quality of …

We study networked control of a dynamical process over a lossy channel with a hybrid
automatic repeat request protocol that connects a sensor to an actuator. The dynamical …

Age of information (AoI) defines the freshness of status update in real-time systems, such as
the Industrial Internet of Things (IIoT), and can be affected by delays and transmission error …

In the upcoming satellite-integrated Internet, a noted limitation is the non-trivial propagation
latency due to the long distances. To support the emergent timeliness applications …

We consider a time slotted communication network with a base station (BS) and a user. At
each time slot a fresh update packet arrives at the BS with probability p>0. When the BS …
