IoT-Fog-Blockchain Framework : Opportunities and Challenges

Exploring the unique blockchain-internet of things (IoT) framework may be an attractive structure for enhancing communications efficiency in the 5G networks. The wireless communication would have been the largest research area that allows users to communicate with each other. Nowadays, high-speed, smart, efficient with many technologies, such as low power consumption, and so on, appear to be available to communicate with each other in today's globe. Throughout this framework, the expansion of fog features is enabled for physical objects within IoT. Several of the challenging issues in the field of wireless communications would be to build a new blockchain-based virtualization system across the IoT architecture. The main purpose of this framework is to connect blockchain technology to the IoT and fogging or maintains the IoT cryptography secured when transactions occurred. This strengthens blockchain and fog to build an effective IoT communication system. The recommended method is an important estimation of the extensive work
