Blockchain Enabled IoT Edge Computing

Number of internet connected devices is increasing as IoT is getting more prevalent. Volume of data collected by IoT sensors is very high and requires considerable resources for data processing like analytics. Edge processing enables getting the sensor data processed closer to the source. It's not always possible and/or economical to set up a resource intense infrastructure at the edge. This paper proposes use of blockchain based decentralized application to enable IoT edge processing. With this setup, it is possible for a resource owner to join the ecosystem and to lend the compute resources as needed. IoT devices can offload some of the edge computation to the resource owner nodes as and when required. This paper explains architectural components and overall solution for implementation. Based on the usecase of video analytics at edge, experimental setup is implemented for the IoT edge solution using hyperledger sawtooth blockchain.
