Part of the Lecture Notes in Networks and Systems book series (LNNS,volume 140)


In the era of the revolutionized world with a huge enhancement in the technology, various interconnecting devices are able to communicate in order to automate the today tasks for us. These IoT nodes require security, reliability, robustness and efficient management. This abundant information that shares in the network requires security measures. Blockchain technology has revolutionary impact on the world by transforming the way for sharing the information and provides a distributed environment with no centralized authority support in various industries. This paper emphasizes on the challenges faced in the integration of IoT and blockchain, surveys the various applications to analyse the potential of blockchain in the upgradation of IoT and addresses the development of some privacy preservation techniques for IoT system operating over blockchain infrastructure. This paper reflects the comparative analysis of various smart contract mechanisms used for the IoT platforms like Iota, Iotex and Iotchain. In this, we proposed the methodologies of integration used for the integration of both the technologies for the performance enhancement with respect to various parameters.
