TRANSACTION DELAY OF DATA TRANSMISSION BETWEEN SENSOR AND BLOCKCHAIN TECHNOLOGY FOR THE HEALTHCARE DOMAIN USING CONSENSUS MECHANISM

Abstract

Blockchain is being used for sharing of data among the different nodes. In respect to maintain the confidentiality of data, the blockchain has been adopted with its high value data secrecy. Sensor nodes and blockchain nodes have been considered and concept of Diffie-Hellman is been employed in connection with both mentioned nodes. In this article/concept, Message authentication code (MAC) was adopted so that the secrecy of data can be protected thereafter, calculated the transition time i.e., time involved in transferring data from sensor nodes to blockchain nodes. One of the prominent methods which has come into the light smooth transaction of data and to ensure a stable security is blockchain Technology. Using the IoT with the backing of blockchain technology enables a system to work more smoothly.  The Healthcare status of a patient can easily be tracked by using IoT. It is very big challenge in today’s time to interlink block chain technology with Internet of things (IoT). Both the nodes are linked with shared key and it generate a common code referred as HMAC signature. The concept of machine learning introduced to remove the outliers of data before feeding it into the sensor node. The outcomes/result/research shows that as the test load is increasing, the corresponding throughout is getting advance/increase and after attaining a particular threshold it starts dropping.  Thereafter the phenomenon is  best  suitable for IoT system.
