The increasing use of wireless sensor networks (WSNs) calls for solutions for mastering the complexity due to WSN heterogeneity and differentiated user needs. This paper presents an architecture, named iCAAS, designed to collect, to store, to manage and to make available to users data received from heterogeneous WSNs. The aim of the architecture is to adaptively deliver data to users depending on their specific interests and irrespective of adopted terminals (e.g., mobile device, workstation, ...) and of sensor networks details. The contribution of the paper is twofold. First we detail the requirements that these types of architectures should meet to fill the gap between sensors details and users needs. Second, we describe the structural organization of the proposed architecture, designed by taking into account the defined requirements. Implementation details and case studies are also provided, showing the effectiveness of the architecture when used in real world application scenarios.
