ABSTRACT
The Internet-of-Things (IoT) is becoming mature. It is moving from the research labs into production environments. In the initial phase, there are mainly small installations focused on a specific application, but, on the horizon, real and wide-scale deployments become visible, especially for realizing the concept of smart cities. The basis for deriving such information is provided by IoT analytics. Individual measurements, e.g., if individual cars or persons are passing a certain spot, may only provide limited benefits, but if the overall traffic situation can be derived or the behaviour of crowds can be determined, suitable actions can be taken. The chapter examines the edge-based approach for data analytics, which is still at a very early stage in the Smart City context and in general in the Internet-of-Things world. Fog computing is a term first advertised by Cisco, also known as Edge Computing.
