Prototype Design and Test of Blockchain Radio Access Network

The concept of hlockchain radio access network (B-RAN) was proposed to integrate cross-network resources including spectra and infrastructures to meet the explosive growth of diverse connectivity needs. In this work, we consider the prototype design of B-RAN and address the issues arising in its implementation. To reduce the access delay, we develop a fast smart contract deployment (FSCD) for B-RAN. Also, we propose the concept of digitized spectrum assets (DSA) in BRAN for efficient spectrum sharing and management. We further summarize and demonstrate the B-RAN prototype enhanced by the newly introduced FSCD and DSA, along with the overall workflow. We apply comprehensive simulations based on an in-house experimental platform to illustrate the effectiveness of the proposed B-RAN prototype.
