Automation, security and surveillance for a smart city: Smart, digital city

The Internet of Things (IoT) is when the Internet and network of sensors flourish to places such as home and industrial level automation, traffic control, synchronization of emergency services and surveillance over Wi-Fi. It is the network of interconnected vehicles, physical appliances, and electronic sensors and actuators which are bound together via software. The concept of `SMART CITY' is an emerging field in current research since people are becoming more time conscious. With the rising population, it is becoming increasingly difficult to control things manually. The current situation demands control of appliances or services remotely around the globe. This paper focuses specifically on the utilization of the city/campus-wide Wi-Fi, existing telecommunication service, various sensors and the widely used Android Phone to develop a `SMART CITY' where every corner of the city is connected to a central control unit over Wi-Fi. This paper also illustrates the working prototype of the proposed vision of the `SMART CITY'.
