  Abstract: In big cloud structures or large data structures, fog computing could be interpreted, referring critically to the growing issues and problems in accessing the information among the Internet of things (IoT) devices. Fog computing can be used to compute, store, control and connect smart devices to each other. IoT is an architecture of uniquely identified interrelated physical things, these physical things are able to communicate with each other and can transmit and receive information. This research presents a framework of the combination of the Internet of Things (IoT) and Fog computing. The blockchain is also the emerging technology that provides a hyper, distributed, public, authentic ledger to record the transactions. Blockchains technology is a secure technology that can be a great benefit to the next generation computing. The confluence of fog, blockchains, and IoT in this area introduces a new incentive. In this research work, the author mentions the convergence of blockchain, fog and IoT technological innovations to present an effective communication framework. The framework is implemented and tested using different scenarios.
