IoT: The kernel of smart cities

Smart devices are generating at an exponential rate and sois their connectivity to the internet. An estimate suggests that 30 billion smart devices would be connected to each other via IoT by 2020. IoT for smart cities provides us with a means to improve the quality of living by providing various applications such as administration, commerce, management, transportation, healthcare etc. IOT for smart cities is capable of reducing a lot of man-power and work hours to a great extent. To build a smart city it takes wireless networks, telecommunication networks, sensors (GPS, RFID, laser), smart devices which stay connected to each other and communicate to take necessary action. Also, a lot of analytical information is generated in this process which is of extreme use in determining what changes should be made in which area. Building an IoT blueprint for a city is actually a very complex job due to the variety of smart devices present. Smart cities are those which make use of these smart devices to carry out various functions such as traffic control, lighting control, connecting multiple cities together, pollution control etc. The dream of smart cities can totally change the way we look at things. Furthermore, the paper will present details about case study of Spain in Monitoring green areas to develop a Smart Garden system and to manage conditions and needs of green areas in real-time.
