Spect-NFT: Non-Fungible Tokens for Dynamic Spectrum Management

Abstract

Dynamic Spectrum Sharing (DSS) is a pivotal technology for optimizing spectrum utilization and fostering efficient sharing among diverse users. However, existing DSS approaches face significant challenges related to security and privacy vulnerabilities, leading to fraudulent practices within spectrum marketplaces. In this paper, we introduce Spect-NFT, a novel framework leveraging Non Fungible Tokens (NFTs) to address these limitations and enhance the spectrum-sharing ecosystem’s efficiency and revenue. Spect-NFT employs NFTs to authenticate ownership of spectrum bands, mitigating fraudulent activities and improving trust among participants. Additionally, Spect-NFT introduces digital Permission Tokens (PTs) to facilitate seamless spectrum sharing between primary users (PUs) and secondary users (SUs) enabling the sharing of a single NFT among multiple owners. We present a methodology for converting spectrum licenses into NFTs and demonstrate the feasibility of our approach using the Ethereum Blockchain. Our proof of concept solution showcases Spect-NFT’s tamperresistant characteristics and its potential to revolutionize DSS paradigms.
