Cloud Technology might be used for processing and storing the huge amount of data generated from users and thousands of heterogeneous kind of sensors deployed all around. In the near future, the simple use of the cloud ”elasticity”, where computation and storage resources can be on-demand resized, might be not useful enough to support the increasing rate of data production. In this work we introduce a new cloud architecture able to virtualize different types of sensing infrastructures in ”virtual sensing elements”, adding new capabilities of data processing. This architecture named CLEVER is capable to analyze and filter data from sensor networks and provide them through advanced services, in order to avoid the rough flooding of data within the cloud. CLEVER has a peripheral decision-maker, able to interact with SNs, and a high level intelligence, able to meet the new requirements of sensed environments, and the manipulation of data. The efficient communication system at the base of CLEVER allows to efficiently manage resources and services, balancing data offerings and demands. [ABSTRACT FROM PUBLISHER]

Smart Cities offer a new approach for optimizing services, reducing costs, simplifying the management of Future Cities, enabling new services for citizens. In the Future Internet initiatives, Sensors Networks assume even more a crucial role, especially for making smarter cities. Sensors, becoming smart, will represent the peripheral elements of a complex future ICT world. However, due to the specific application field, smart sensors are very heterogeneous in terms of communication technologies, sensing features and elaboration capabilities. To overcome issues due to the high heterogeneity in this paper we present a new architecture able to make a dual abstraction of complex sensing infrastructures along with data they collect. An important key of this work is to provide a service at world wide level, that is scalable and flexible. The architecture implementation is based on Sensor Web Enablement standard specifications and makes use of the Contiki Operating System for accomplishing the Internet of Things.
