Blockchain-IoT peer device storage optimization using an advanced time-variant multi-objective particle swarm optimization algorithm

Abstract The integration of Internet Things devices onto the Blockchain implies an increase in transactions that occur on Blockchain, thus increasing storage requirements. A solution approach is to leverage cloud resources for storing blocks within chain. paper, therefore, proposes two solutions this problem. first being improved hybrid architecture design which uses containerization create a side chain fog node connected it and Advanced Time-variant Multi-objective Particle Swarm Optimization Algorithm (AT-MOPSO) determining optimal number should be transferred storage. This algorithm time-variant weights velocity particle swarm optimization non-dominated sorting mutation schemes from NSGA-III. proposed was compared with results original MOPSO algorithm, Strength Pareto Evolutionary (SPEA-II), Envelope-based Selection region-based selection (PESA-II), AT-MOPSO showed better than aforementioned algorithms cost query probability optimization. Importantly, achieved 52% energy efficiency To show how can applied real-world system, BISS industrial adapted modified used existing systems benefits provides.
