ABSTRACT
The Internet of Things (IoT) can be seen, in short, as physical objects composed of software and hardware and connecting to networks, either the Internet or creating local links. The advances in embedded systems have converged with the increasingly complex urban needs enunciated during the Kyoto Protocol in 1997 to give rise to what have been known as smart cities. This chapter aims to explore how IoT has become the backbone on which smart city applications and systems have relied on. In this chapter, we use a motivational example of a smart home in the context of a smart city to show how the concepts of IoT and smart city are intertwined. Next, we discuss common characteristics between both technologies and the challenges that still remain.
