It is predicted that about 70% of the world’s population will start living in cities and surrounding regions by 2050.In order to efficiently manage the critical infrastructure and services of a city these need to evolve into a ‘smart city’.
A smart city according to Forrester, is one that uses information and communication technologies (ICT) to make the critical infrastructure and services of a city, such as public safety, transportation and utilities more aware, interactive and efficient.
The realization of smart city is now becoming possible with the emergence of Internet of Things (IoT), which radically evolves the current Internet into a network of interconnected objects, such as sensors, parking meters, energy measuring and actuators. These networked devices have the ability to compute, sense and interact with their surroundings in fine and spatial and temporal detail, and generate a vast amount of data.
Internet of Things (IoT) is based on a set of technologies intrinsically related with devices’ characteristics and their level of pervasiveness. In general, the building blocks of IoT are tiny, resource constrained wireless devices that communicate using the Internet Protocol (IP). Mobile devices without stringent resource constraints like ; smart phones and tablets share their resources with surrounding IoT devices which are typically resource constrained these in turn share their physical world interfaces, thus extending the capabilities to a new level of
