What is Blockchain Radio Access Network?*

The continually rising demand for wireless services and applications in the era of Internet of Things (IoT) and

To meet the rapid growth need of mobile data services, blockchain radio access network (B‐RAN) has emerged as a decentralized, trustworthy radio access paradigm spurred by blockchain technologies. However, many characteristics of B‐RAN remain unclear and hard to characterize. In this chapter, we develop an analytical framework to model B‐RAN and provide fundamental analysis. Starting from the block generation process, we establish a queuing model based on a time‐homogeneous Markov chain. Through the queuing model, we evaluate the performance of B‐RAN with respect to latency and security considerations. We further uncover a more comprehensive picture of the achievable performance of B‐RAN by connecting latency and security. At last, we present experimental results via an innovative prototype and validate the proposed model.
