The arrival of Internet of Things (IoT) as contributes to the development of smart homes and intelligent transportation systems accelerates the construction of sustainable smart cities for the future. And with an estimated 70% of the world's population living in cities by 2050, smart and sustainable cities have become a major policy priority for administrations worldwide. In this paper, we are proposed a new approach namely as " Cognitive Artificial intelligence and Internet of vehicle (CAI-IoV-), that explain how Artificial Intelligence Powers Smart Cities of Tomorrow, the advancement of information and communication technologies (ICT), artificial intelligence, and the Internet of Things play a crucial role in increasing efficiency in all industrial sectors and enabling innovations such as Intelligent Transport Systems (ITS) and "smart" management for water, energy, and waste. Our approach is widely recognized that building "smart" technologies in an existing smart city or developing a sustainable smart city itself is a best issue that requires better cooperation and greater integration in decision-making by different stakeholders. This is a major area where the Union can provide valuable assistance.
