What is Sinknode/Base Station

IoT is an assembly of equipment of different calibers and functionality working towards a single goal. A blockchain is a computerized record that contains the whole history of exchanges made on the system. A multi-WSN arrangement model is structured. The hubs of the IoT are isolated into base stations, group heads, and conventional hubs as per their capacities, which encourage the administration and participation of the hubs. A hybrid blockchain model is proposed. To fit the multi-WSN arrange model better, as indicated by the various capacities and energies of various hubs, neighborhood blockchain and open blockchain are sent between group head hubs and base stations individually, and a crossbreed blockchain model is framed. A shared validation plot for IoT hubs is proposed. For group head hubs, the creators utilize the worldwide blockchain for validation, and for customary hubs, they utilize the nearby blockchain for confirmation. The proposal aims in increasing reliability by 1.17% and minimizes sinkhole attack by 2.42% compared to previous contribution.
