VLC in 6G Networks: From Laboratory Innovation to Real-World Infrastructure
Published:
As we move closer to the 6G era (expected around 2030), Visible Light Communication (VLC) is evolving from a promising laboratory technology into a core component of next-generation wireless infrastructure. In this post, I share my perspective on where VLC fits in the 6G puzzle — and why hybrid VLC/RF systems are the key to unlocking its potential.
The Open-Source AI Renaissance: Rivaling Proprietary Giants
Published:
The narrative that “proprietary is better” in Artificial Intelligence is officially dead. By early 2026, the gap between closed-source giants and the open-source community has not just narrowed—it has effectively closed.
Quantum-Safe Security Meets Visible Light Communication: Where VLC Fits in Future-Proof IoT Networks
Published:
VLC is often described as “naturally secure” because light does not penetrate walls like RF. That’s a useful intuition—but security engineering needs a more precise view.
Quantum-Era IoT Security: Threats, Post-Quantum Cryptography, and a Practical Migration Roadmap
Published:
Quantum technologies are moving from theory to engineering reality. For IoT systems, the most immediate implication is not “quantum computers running our networks”, but the security risk that future quantum computers could break widely-used public‑key cryptography.
The Future of Agentic AI in Agriculture: Research Roadmap 2026-2030
Published:
As we advance our AGRIFARM-AI project, I want to share our research vision for the next five years. The convergence of agentic AI, multi-agent systems, and precision agriculture opens unprecedented opportunities for autonomous food production.
Federated Learning for Cross-Border Agricultural Intelligence
Published:
Agricultural data is inherently distributed across farms, regions, and countries. Federated Learning (FL) enables collaborative AI training without centralizing sensitive farm data—a critical requirement for both privacy and sovereignty.
Climate Resilience Through AI: From Forecast to Action
Published:
Climate change poses existential threats to global food security. While AI-powered climate models excel at prediction, a critical gap remains: translating forecasts into farmer actions. Our research addresses this through a complete causal chain from data to validated outcomes.
Multi-Agent Reinforcement Learning for Autonomous Precision Farming
Published:
Precision agriculture demands coordinated decision-making across multiple subsystems—irrigation, fertilization, pest control, and energy management. Multi-Agent Reinforcement Learning (MARL) provides an elegant framework for this coordination challenge.
Intelligent Management Systems for Smart Greenhouses: From Retail to Agriculture
Published:
The transition from retail indoor environments to controlled environment agriculture (CEA) represents a natural evolution for Intelligent Management Systems (IMS). Our research, originally validated at ACM MobiCom 2023 for hybrid VLC/RF networks, is now being adapted for greenhouse agriculture with remarkable potential.
