A proactive role of IoT devices in building smart cities

Due to rapid advancement in technology the world is rapidly changed to face the upcoming challenges and going towards automation. The use of various IoT devices is making a vast approach and every happening becomes part of the network and due to that towns are converting into smart cities. The IoT devices collect the data of every happening smartly and send it for further processing. An imperative part of these devices is containing the wireless sensors used for building smart cities. A giant set of data is collected in the sensors and is stored in the data center. Subsequently, the huge data becomes an exorbitant mountain that must be managed smartly if a smooth operation is required. In this study, how such big data can be managed shrewdly is going to explore and the proactive role of IoT sensors are investigated which helps in building the future smart cities more independently. The impact of services such as Smart transport, smart energy, smart infrastructure, smart health, smart agriculture, and smart recreation in respect of smart cities and the old traditional city has been analyzed through an Analytic Hierarchy Process (AHP). The obtained results showed a satisfactory level of local communities about 98% of people living in smart cities are satisfied in contrast to people living in old traditional cities and others having a neutral opinion.
