Decentralizing Private Blockchain-IoT Network with OLSR

With data transparency and immutability, the blockchain can provide trustless decentralized services for Internet of Things (IoT) applications. However, most blockchain-IoT networks, especially those with a private blockchain, are built on top an infrastructure-based wireless network (i.e., using Wi-Fi access points or cellular base stations). Hence, they still under risk Single-Point-of-Failure (SPoF) layer, hindering decentralization merit, example, when stations get failures. This paper presents Optimized Link State Routing (OLSR) protocol-based solution that issue in application. By decentralizing underlying OLSR, avoid SPoF automatically recover after failure. Single connections be extended to multiple ad hoc hops. Services over become flexible fit various IoT scenarios. We show effectiveness our by constructing Ethereum running devices Raspberry Pi model 4) environmental sensing Particular Matter (PM)). The use OLSR form network. environment collected propagated transactions pre-loaded smart contract periodically. then evaluate network’s recovery time facing link error. evaluation results also transaction-oriented latency block-oriented latency, which indicates blocks have high transmission quality, while transferred individually.
