A Conceptual Blockchain Architecture for Dynamic Spectrum Access in 6G CR-IoT Networks: An Analytical Review
محتوى المقالة الرئيسي
الملخص
Even though 6G networks will provide not just terabit-level throughput and sub-millisecond-level latency but also connect exponentially more devices, the explosive growth of IoT applications is fueling an unprecedented demand for wireless spectrum. Traditional, static allocation schemes can’t keep up with this scale and dynamism, leading to underuse and conflict. Most blockchain solutions for dynamic spectrum access lack robust security measures against emerging quantum-era threats and do not incorporate quantum-resistant cryptography, which is essential in future 6G environments. In this research article, we propose a five-layer conceptual blockchain architecture to enable DSA in 6G cognitive radio IoT networks, combining a permissioned PBFT blockchain with quantum secure cryptography (ECC and QKD), smart contracts, edge-computing nodes, and AI-driven spectrum intelligence, the architecture integrates trust management, quantum-safe cryptography, and intelligent decision-making to ensure reliable spectrum access in future 6G environments. The system model, layered architecture, and associated security and consensus mechanisms are presented. While implementation remains future work, this conceptual design offers a strong theoretical foundation for building robust, secure, and scalable spectrum management systems in next-generation wireless networks.
