Multi-Agent Reinforcement Learning for Joint Handover Management and Power Allocation in Multi-Orbit Satellite Networks
Yassine Afif, Ashutosh Balakrishnan, Philippe Martins +3
Future sixth-generation non-terrestrial networks are expected to combine low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary Earth orbit (GEO) satellites, whose comp…
Joint Visibility Analysis of RIS in Non-Terrestrial Networks through Stochastic Geometry
Ashutosh Balakrishnan, Junse Lee, Francois Baccelli
Non-Terrestrial networks (NTNs) are a key theme in upcoming 6G communications, especially for ubiquitous coverage. Urban environments, comprising of high rise buildings often resul…
Adaptive Multi-UAV Relay Deployment Framework in Satellite Aerial Ground Integrated Systems
Bhola, Yu-Jia Chen, Ashutosh Balakrishnan +2
The sixth generation (6G) communication networks are expected to provide high data rates, ultra-reliable communication, and massive connectivity, especially in challenging environm…
Timing advance and Doppler shift estimation in LEO satellite networks: A recursive Bayesian study
Ashutosh Balakrishnan, Pierre Popineau, Philippe Martins
Low earth orbit (LEO) satellite based non-terrestrial networks are a key theme of the upcoming 6G networks. These space networks are proposed to be used for high-mobility use-cases…
Cooperative UAV-Relay based Satellite Aerial Ground Integrated Networks
Bhola, Yu-Jia Chen, Ashutosh Balakrishnan +2
In the post-fifth generation (5G) era, escalating user quality of service (QoS) strains terrestrial network capacity, especially in urban areas with dynamic traffic distributions.…
