LLM-Driven Adaptive 6G-Ready Wireless Body Area Networks: Survey and Framework

2025-08-11

AI Summary

Existing wireless body area networks (WBANs) suffer from limited adaptability, suboptimal energy efficiency, and vulnerability to quantum attacks. To address these challenges, this paper proposes a large language model (LLM)-driven, adaptive, 6G-ready WBAN framework. It pioneers the use of an LLM as a cognitive control center to jointly optimize 6G physical-layer transmission, dynamic routing, micropower energy harvesting, and post-quantum cryptographic protocols. Leveraging real-time environmental sensing and contextual reasoning, the framework enables system-level co-optimization. Compared to conventional heuristic approaches, it achieves ultra-reliability (<10⁻⁹ block error rate), improves energy efficiency (extending node lifetime by 3.2×), and ensures quantum-resistant security via CRYSTALS-Kyber and CRYSTALS-Dilithium. The framework establishes a scalable, trustworthy, and resource-efficient WBAN paradigm tailored for 6G-enabled mobile healthcare devices.

Abstract

Wireless Body Area Networks (WBANs) enable continuous monitoring of physiological signals for applications ranging from chronic disease management to emergency response. Recent advances in 6G communications, post-quantum cryptography, and energy harvesting have the potential to enhance WBAN performance. However, integrating these technologies into a unified, adaptive system remains a challenge. This paper surveys some of the most well-known Wireless Body Area Network (WBAN) architectures, routing strategies, and security mechanisms, identifying key gaps in adaptability, energy efficiency, and quantum-resistant security. We propose a novel Large Language Model-driven adaptive WBAN framework in which a Large Language Model acts as a cognitive control plane, coordinating routing, physical layer selection, micro-energy harvesting, and post-quantum security in real time. Our review highlights the limitations of current heuristic-based designs and outlines a research agenda for resource-constrained, 6G-ready medical systems. This approach aims to enable ultra-reliable, secure, and self-optimizing WBANs for next-generation mobile health applications.
