Abstract
Today, we live in a society where digital communication systems are so advanced that by the mid 2050’s the world will be completely filled by smart buildings on the internet highway like those portrayed in science fiction movies. This is possible because of tech savvy tiny sensors or Internet of Things (IoT) devices embedded in the smart network in order to collect meaningful information about the citizens and their interaction with the ubiquitous environment. Smart sustainable cities are modelled on the Internet of Things blending ICT for better standard of living and citizen services. IoT will modify indoor temperatures and switch off unnecessary lights in homes, detect snags in equipment and fix machines remotely, and provide commuters with information on traffic jams on the go. IoT in smart cities can be implemented by the development authorities but the stake holders of this task are citizens, the municipal government and private organizations engaged in this partnership. Using sophisticated ICT systems makes the city smarter and improves community building and connectivity by interweaving all the components of a city. Privacy and security are the two watch words when it comes to capturing citizens’ data. This data needs to be anonymised before it reaches the civic authorities. This study evaluates the advantages and disadvantages of using IoT in Indian smart cities after discussing an international case study of a smart sustainable city.
