Implementation of Blockchain-Based Dynamic Spectrum Management and Access Platform

Abstract

With the rapid development of the information communication technology more and more devices have their demands on the spectrum resource to access the internet service However spectrum resource is limited It’s a big challenge for mobile operator manufacture and government to make spectrum usage more efficient In order to manage the spectrum resource efficiently this study aims to build a dynamic spectrum management and access platform according to the IEEE 1900 standards Also this study includes spectrum transaction which is implemented with blockchain technology into the spectrum management platform Raspberry Pi 3 Model B equipped with USRP (universal software radio peripheral) is used in this study as a CR (cognitive radio) device In dynamic spectrum access scheme a CR device would sense the radio environment before transmitting data in order to avoid possible interference If the device concludes that other devices nearby are using the certain spectrum resource the device itself will dynamically adjust its key parameters such as carry frequency and modulation scheme Spectrum management database plays another significant row in this study When the database receives a transmitting request from CR device it must determine whether interference happens To make the spectrum transaction system safe and sound blockchain technology is employed in this study Blochchain is resistant to modification of each transaction record so it can assure the safety of whole system without any malicious attack and simultaneously verify every transaction in the dynamic spectrum management and access platform
