Wireless sensor networks (WSN) are spreading as a common mean for mitigating installation and management cost in environment monitoring applications. The increasing complexity ad heterogeneity of such WSN and the differentiated users needs calls for innovative solutions for managing and accessing produced data. This paper presents an architecture, named iCAAS, designed to collect, store, manage and make available to users data received from heterogeneous WSNs. The objective of the architecture is to adaptively deliver data to users depending on their specific interests and transparently to adopted terminals and of networks details. The contribution of the paper is twofold. First the authors detail the requirements that these types of architectures should meet to fill the gap between sensors, details, and users needs. Second, the authors 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. Finally, iCAAS architecture’s scalability is tested against the number of concurrent client querying the same time.

The design of iCAAS started from the definition of several functional requirements: data processing, WSN setup, configuration, user management; and non-functional requirements: interoperability, adaptability, responsiveness, as detailed in the following.
