Blockchain framework for IoT data quality via edge computing

Smart home presents a challenge in control and monitoring of its wireless sensors networks (WSN) and the internet of things (IoT) devices which form it. The current IoT architectures are centralized, complex, with poor security in its communications and with upstream communication channels mainly. As a result, there are problems with data reliability. These problems include data missing, malicious data inserted, communications network overload, and overload of computing power at the central node. In this paper a new architecture is presented. This architecture based in blockchain introduce the edge computing layer and a new algorithm to improve data quality and false data detection.
