Green IoT for Eco-Friendly and Sustainable Smart Cities: Computer Integration in sustainability

The evolution of the Internet of Things this technology and its integration into smart cities has changed every people's life and their working system. IoT technologies face several kinds of challenges or issues, such as power consumption boosting, and creating various pollutions which are toxic, as well as this IoT produces many kinds of E-waste which is harmful to the smart cities. Environmentally friendly the smart city applications must be demanded to move to a green IoT, this friendly environment leads by the Green IoT which is sustainable for the smart cities. Therefore, it is very introductory to facilitate pollution, traffic waste, consumption of energy, the safety provided to the public, hazards, usage of resources, life quality, environment sustaining, and management of the cost to address those techniques and strategies. Those kinds of surveys help to focus on providing exhaustive reviews of the advanced techniques and also strategies because the Green IoT wants to make the city into a smarter city, eco-friendly, and sustainable for the city people. Furthermore, to address the requirements of the smart cities that merge into the IoT and its capabilities with the probable characteristics and that is the main focus of this survey. IoT wants to be added everything that needs to build a smarter city that could be connected at any time or anywhere by using any medium. Finally, in this research study, the researchers discuss the challenges and also look at the opportunities for their future help to build a smart city by taking the help of Green IoT.
