Effective Dual Subgradient Methods Through Sequential Subgradient-Aligned Rays
Hansi Abeynanda, Chathuranga Weeraddana, Carlo Fischione
In this paper, we propose an efficient subgradient-based framework, referred to as the sequential subgradient-aligned rays (SSAR) method, for improving the convergence performance…
6G Resilience -- White Paper
Hirley Alves, Nurul H. Mahmood, Onel L. A. López +36
6G must be designed to withstand, adapt to, and evolve amid prolonged, complex disruptions. Mobile networks' shift from efficiency-first to sustainability-aware has motivated this…
Resilient-Native and Intelligent Next-Generation Wireless Systems: Key Enablers, Foundations, and Applications
Mehdi Bennis, Sumudu Samarakoon, Tamara Alshammari +3
Just like power, water, and transportation systems, wireless networks are a crucial societal infrastructure. As natural and human-induced disruptions continue to grow, wireless net…
Opportunistic Beamforming and Dynamic Scheduling for Multi-User MIMO-ISAC Systems
Tharaka Perera, Saman Atapattu, Chathuranga Weeraddana +1

From Raw Data to Structural Semantics: Trade-offs among Distortion, Rate, and Inference Accuracy
Charmin Asirimath, Chathuranga Weeraddana, Sumudu Samarakoon +2
This work explores the advantages of using persistence diagrams (PDs), topological signatures of raw point cloud data, in a point-to-point communication setting. PD is a structural…
On the Characteristics of the Conjugate Function Enabling Effective Dual Decomposition Methods
Hansi Abeynanda, Chathuranga Weeraddana, Carlo Fischione
We investigate a novel characteristic of the conjugate function associated to a generic convex optimization problem, which can subsequently be leveraged for efficient dual decompos…
On the Convergence of Inexact Gradient Descent with Controlled Synchronization Steps
Sandushan Ranaweera, Chathuranga Weeraddana, Prathapasinghe Dharmawansa +1
We develop a gradient-like algorithm to minimize a sum of peer objective functions based on coordination through a peer interconnection network. The coordination admits two stages:…
