Advanced sensing and internet of things in smart cities

Internet of Things is largely perceived as a collection of interconnected “things” within smart cities. However, it can also be observed as a collection of data, shared between different devices and advanced sensors, then analyzed and used in different aspects of the smart city. In this paper, we introduce a similarity between a layered network architecture and “layered smart cities architecture” used for collection and sharing of big data with the aid of a cloud infrastructure in the smart city. The Internet of Things is discussed in the viewpoint of specific applications and technologies, i.e. layers in smart cities, such as: smart homes and automation, energy efficiency, e-health, intelligent transportation, waste and water management, smart agriculture, security and emergency services, application services and connected smartphones, etc.
