Blockchain Based Spectrum Sharing

TL;DR

This paper proposes a blockchain-based spectrum sharing framework that uses interference-based consensus and smart contracts to enable distributed spectrum management while addressing interference and coordination challenges.

Contribution

It introduces an interference-based consensus mechanism and smart contracts for blockchain-enabled spectrum sharing, expanding on existing centralized and distributed approaches.

Findings

Proposes interference-based consensus for spectrum sharing

Introduces smart contracts to manage spectrum transactions

Discusses cross-tier spectrum coordination and incentives

Abstract

Spectrum sharing has long been considered as method to improve spectrum resource utilization. Centralized geolocation database approach has been accepted globally for commercial applications. Recently blockchain has been considered as a platform to support spectrum sharing in a distributed manner. Like other commodities, spectrum or right of spectrum usage can be exchanged through blockchain. However, this leads to changes of the location where a particular frequency channel is utilized which brings potential interference. In this paper, we present the interference based consensus and smart contract for blockchain based spectrum sharing. We will also introduce the other aspects of blockchain such as cross train transaction, cross tier spectrum coordination and incentive mechanism that need to be studied for spectrum sharing applications.
