BALAdIN: truthfulness in collaborative access networks with distributed ledgers
Résumé
Distributed Ledger Technology (DLT), also known as "Blockchain" is one of the trendiest digital innovations in our era. While firstly applied to cryptocurrencies, the trustworthiness inherent to DLT paved the way to many new usages notably in sectors such as land registration or banking where confidence in transactions is crucial. In the telecommunications sector, DLTs have enabled the development of future network architectures, such as new decentralised and multiactor access networks. Having identified this as a great opportunity, we designed BALAdIN, a novel Blockchain-powered decentralised application that improves network coverage thanks to partnerships. Indeed, it allows a crowd of local actors such as shop tenants to deploy mobile cells with the help of a consortium of telcos. The traffic conveyed by each actor is traced thanks to a decentralised and trustworthy network monitoring mechanism we have designed. This mechanism both solves the centralisation dilemma caused by Blockchain Oracles and allows each actor to be rewarded depending on usage. In this paper, we focus on the description of this network usage monitoring mechanism. We then study the feasibility of its implementation onto regular Blockchain by studying its performance regarding the throughput and the propagation of the resulting Blockchain transactions. Finally, we derive a scalable deployment scheme for our novel Blockchain-powered decentralised network metering application BALAdIN.
