This paper presents a case study where wireless sensor networks (WSNs) are exploited to provide indoor localization. Different low-complexity localization techniques, based on received signal strength indicator, are investigated and experimented. To develop a localization system several aspects has to be taken into account at different levels: technology, algorithms, and specifications imposed by location-aware applications. In particular, the following issues are addressed in this work: WSN deployment planning, characterization of indoor propagation, presence of low-reliability measurements, on-field characterization of the deployed platform. The estimated position enables location-aware applications and services in contextaware platforms. Starting from typical context-aware application requirements we give an example of planning and tuning for the whole platform in addition to experimental results in terms of precision and accuracy of the localization platform.

Abstract
This paper presents a case study where wireless sensor networks (WSNs) are exploited to provide indoor localization. Different low-complexity localization techniques, based on received signal strength indicator, are investigated and experimented. To develop a localization system several aspects has to be taken into account at different levels: technology, algorithms, and specifications imposed by location-aware applications. In particular, the following issues are addressed in this work: WSN deployment planning, characterization of indoor propagation, presence of low-reliability measurements, on-field characterization of the deployed platform. The estimated position enables location-aware applications and services in contextaware platforms. Starting from typical context-aware application requirements we give an example of planning and tuning for the whole platform in addition to experimental results in terms of precision and accuracy of the localization platform.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
