HAL - INRIA :: [hal-01004489, version 2] Towards a Smart City based on Cloud of Things
Smart City represents one of the most promising and prominent Internet of Things (IoT) applications. In the last few years, indeed, smart city concept has played an important role in academic and industry fields, with the development and deployment of various middleware platforms. However, this expansion has followed distinct approaches creating, therefore, a fragmented scenario, in which different IoT ecosystems are not able to communicate between them. To fill this gap, there is a need to re-visit the smart city IoT semantic and offer a global common approach. To this purpose, this paper browses the semantic annotation of the sensors in the cloud, and innovative services can be implemented and considered by bridging Clouds and Internet of Things. Things-like semantic will be considered to perform the aggregation of heterogeneous resources by defining the Clouds of Things paradigm. We survey the smart city vision, providing information on the main requirements and highlighting the benefits of integrating different IoT ecosystems within the cloud under this new CoT vision. This paper also discusses relevant challenges in this research area.
