Centralized Management of Data Collection over Hybrid Networks

This paper presents an example of technology integration useful for the Public Administrations in order to offer services to their citizens. In particular, we describe some applications of sensor networks that exploit hybrid access networks (fiber, wireless, TETRA) based on real prototypes realized by Lepida S.p.A., a company owned by the Public Administrations promoted by the Italian Emilia Romagna Region. A centralized architecture devoted to the data collection, management and publication is discussed and some possible solutions in order to integrate pre-existent autonomous sensor systems in the new efficient centralized one are presented. This system offers the Public Administrations a promising solution for reducing the total costs of the whole service.
