Hierarchical Edge-Cloud Task Offloading in NTN for Remote Healthcare
Alejandro Flores, Danial Shafaie, Konstantinos Ntontin +2
In this work, we study a hierarchical non-terrestrial network as an edge-cloud platform for remote computing of tasks generated by remote ad-hoc healthcare facility deployments, or…
Secure Task Offloading and Resource Allocation Design for Multi-Layer Non-Terrestrial Networks
Alejandro Flores, Isabella W. G. da Silva, Vu Nguyen Ha +4
Remote and resource-constrained Internet-of-Things (IoT) deployments often lack terrestrial connectivity for task offloading, motivating non-terrestrial networks (NTNs) with onboar…
QTCAJOSA: Low-Complexity Joint Offloading and Subchannel Allocation for NTN-Enabled IoMT
Alejandro Flores C., Konstantinos Ntontin, Ashok Bandi +1
In this work, we consider the resource allocation problem for task offloading from Internet of Medical Things (IoMT) devices, to a non-terrestrial network. The architecture conside…
Statistical CSI-Based Distributed Precoding Design for OFDM-Cooperative Multi-Satellite Systems
Yafei Wang, Vu Nguyen Ha, Konstantinos Ntontin +4
This paper investigates the design of distributed precoding for multi-satellite massive MIMO transmissions. We first conduct a detailed analysis of the transceiver model, in which…
