ABSTRACT It is known that IoT can help in building smart cities and smart homes that is the reason, throughout the world and even in countries like India, there is a lot of focus on building smart cities. Of course, the scope of smart cities in every country is different and the scope again depends on the priority areas of each of them and their government. Now for example in India, since the last few years, there have been a couple of cities that have been identified and phase-wise these cities have been given funds to build or to transform them as smart cities. So, when it is being talked about smart cities; in addition to the regular infrastructure that is there in any city, for example, the urban infrastructure consisting of office buildings residential areas, hospitals, schools, transportation, police and so on. Something advanced also needed in addition to make the cities smart. In this paper that advancement i.e., IoT had been described. Keyword: Internet of Things (IoT), Smart Cities, Information and Communication Technologies (ICT) I. INTRODUCTION IoT is the platform in which devices are made connected through the internet for ease in the working of the system [1]. The security of the IoT devices is also needed because in today word max of the data are communicated through the internet [2-5]. So the internet and internet based devices are going to be part of daily life. Smart means that it is in terms of the services that are given to the respective stakeholders of these cities. So, citizens can do things in a better manner in an improved manner than usual and that is made possible with the help of nothing, but the ICT technologies which also includes electronics embedded and different other advanced topologies in electrical sciences and so on [6]. So, computers and electronics put together can make these cities smart. Fig 1: Smart City System II. HUMAN-SMART CITY ANALOGY In a smart city, there is an urban system which uses different ICT tools as shown in fig 3, which makes the infrastructure very interactive, efficient and accessible in an easier manner than before you know it; it should be easily accessible infrastructure and the need for smart cities arose due to different things. There is an ever- growing urban population throughout the world it is not limited to any country, but throughout the world and at the same time the natural resources like coal are depleting at a fast rate. And also at the same time there is a change in climate change in environment throughout. Fig 2 : Human- Smart City Analogy RESEARCH ARTICLE OPEN ACCESS
