The internet of things (IoT) is the network of connected physical devices, objects and sensors to offer many services to the people. These objects are connected through information and communication building blocks. Today IoT has become the most discussed part of every business due to its benefits and this term was first used in 1998 [1]. It is expected that around 3/4th people will live in smart cities and smart surroundings till 2050 [2] and IoT can play a great role in the implementation of the smart city concept. For welfare of people in terms of economics, social and environment, smart city can provide a good platform. Wireless sensor network is the sensing part of IoT which can be combined with urban infrastructure by forming the special skin cover for IoT building blocks. IoT has boosted the development of many applications which makes the use of large amounts of data generated by heterogeneous devices to provide emerging services to the people, various private and public organizations. The applications include the areas of smart home, smart environment, smart energy management and smart grids, smart agriculture and smart traffic management, etc. Heterogeneity of the devices ∗Corresponding author, shalli@ssdwit.org. has acknowledged the potential solutions for all application conditions alarming challenges. These challenges lead to the propagation of various and sometimes unsuited proposals for the practical implementation of IoT. IoT intends to make the internet more submerged and persistent. With the interaction of heterogeneous devices like surveillance cameras, actuators, transport vehicles, domestic devices etc., the IoT will promote the various applications. From these applications the smart city concept is the most interesting idea. Smart City uses the concept of information and communication technologies (ICT) to make the city services more responsive, aware and efficient. To increase the effectiveness of city administration, it is important to understand the need of urbanization. Today only a few organizations have live monitoring of the urban processes. The scheme trail behind is a collection, filtering, analyzing and offline processing of data with action, and these processes are repeated again for the whole system.
