User-Mobility-Aware Optimization of Fiber Placement in Hybrid Fiber-IAB Networks
Piotr Lechowicz, Charitha Madapatha, Carlos Natalino +2
Metaheuristic optimization of hybrid fiber-IAB networks demonstrates that integrating user dynamics into topology design enables more adaptive and cost-efficient backhaul architect…
Energy-Efficient FSO Reconfiguration under User Mobility in Hybrid Fiber-IAB Backhaul
Piotr Lechowicz, Charitha Madapatha, Carlos Natalino +2
User mobility creates stochastic, time-varying backhaul demand that static capacity provisioning cannot match. We propose a closed-loop, load-aware hysteresis controller for hybrid…
RIS-Assisted D-MIMO for Energy-Efficient 6G Indoor Networks
Akshay Vayal Parambath, Jose Flordelis, Venkatesh Tentu +4
We propose an alternating optimization framework for maximizing energy efficiency (EE) in reconfigurable intelligent surface (RIS) assisted distributed MIMO (D-MIMO) systems under…
Joint Fiber and Free Space Optical Infrastructure Planning for Hybrid Integrated Access and Backhaul Networks
Charitha Madapatha, Piotr Lechowicz, Carlos Natalino +2
Integrated access and backhaul (IAB) is one of the promising techniques for 5G networks and beyond (6G), in which the same node/hardware is used to provide both backhaul and cellul…
Reconfigurable Intelligent Surfaces-Assisted Integrated Access and Backhaul
Charitha Madapatha, Behrooz Makki, Hao Guo +1
In this paper, we study the impact of reconfigurable intelligent surfaces (RISs) on the coverage extension of integrated access and backhaul (IAB) networks. Particularly, using a f…
