What exactly is a Smart City and how is it created?  The idea of smart City is to embed the technologically advanced devices which are making the Internet of things a reality into our surroundings. Once the technology is hard wired with the infrastructure, we can interact with these devices using our smart phones or computers and also devices can interact among themselves. For example, a car will be guided to an empty parking space without any human intervention.
