Age of Information in Non-Terrestrial Networks with Energy Harvesting
Fangming Zhao, Nikolaos Pappas, Shi Jin +1
We analyze the timeliness of status-update delivery in a low Earth orbit (LEO) satellite-assisted energy-harvesting Internet of Things network using the Age of Information (AoI) me…
Semantics-Aware Communication:A Differentiated Allocation Perspective
Fangming Zhao, Nikolaos Pappas, Howard H. Yang
We study the joint optimization of timeliness and reliability in semantics-aware Wireless Networked Control Systems (WNCS) under computation resource constraints. The sampled data…
Probing for Better Age of Information in Energy-Harvesting Random Access Networks
Ziyi Li, Fangming Zhao, Howard H. Yang
In this paper, we investigate the impact of channel probing and reservation on the Age of Information (AoI) in energy-harvesting (EH) random access networks, where each source reli…
Energy-Aware Random Access Networks: Connection-Based versus Packet-Based
Anshan Yuan, Fangming Zhao, Xinghua Sun
Characterizing and comparing the optimal energy efficiency in energy-aware machine-to-machine (M2M) random access networks remains a challenge due to the distributed nature of the…
