The region's increased population needs the development of services and infrastructure. IoT devices, automation systems, smartphones, and the intelligent grid are examples of Internet of Things (IoT) capabilities that can help meet demands. Big data, on the other hand, was handled by millions of connected IoT devices. Integrating IoT technologies and improving big data analysis to enable smooth community planning is a big problem. For the technologies for improving service performance and engaged citizenship using big data analytics (BDA) in rural - urban migration, creativity may become unlimited. With the help of IoT devices, rural - urban migration is heading toward data analysis. The integration of technical breakthroughs, data analytical planning, and computational brilliance is lacking in effective urbanization. In urbanization, big data analytics can precisely tackle such circumstances. Medicines, development, population management, human resources, and pollution research are all regions where big data analytics may empower. This analysis study will address and explore various IoT regions, highlighting similarities as well as connections in both networks, and attempting to illuminate regulation endeavors that can be applied in the two settings. We will review current IoT application domains in our paper, which will also reflect the importance for smart rural research: We will review current IoT application domains in our paper, which will also reflect the importance for smart rural research: Ecological Factors and Energy, Transportation and Mobility, Smart Building, Regular Life, Government, And Economy and Environment are the different classifications.
