Blockchain for Economically Sustainable Wireless Mesh Networks
share
Decentralization, in the form mesh networking and blockchain, two promising technologies, is coming to the telecommunications industry. Mesh networking allows wider low cost Internet access while blockchain enables complete transparency and accountability for investments and revenue or other forms of economic compensations from sharing of network traffic, content and services. Crowdsourcing network coverage combined with crowdfunding costs can create sustainable yet decentralized Internet access infrastructures, where every participant can invest in resources, and pay and be paid for usage. While mesh networks and mesh routing protocols enable self-organized networks that expand organically, cryptocurrencies and smart contracts enable the economic coordination among network providers and consumers. We explore and evaluate two existing blockchain software stacks, Hyperledger Fabric (HLF) and Ethereum geth with Proof of Authority (PoA), deployed in a real city-wide production mesh network, and in a centralized laboratory network. We quantify the performance, bottlenecks and identify the current limitations and opportunities for improvement to serve the needs of wireless mesh networks.
