This paper focuses on the analysis of fundamental issues which has to be considered in order to gain voice from a wireless sensor network (WSN) that is assumed to be constituted by MicaZ wireless sensor nodes. Problems related to the transport of an audio signal through a wireless channel and sensor nodes are thus analyzed and a project for an audio(More)
The demonstration proposal focuses on presenting the capabilities of a wireless biometric badge, which integrates a localization and tracking service along with an automatic personal identification mechanism, to control the access to restricted areas with a high level of security. The wireless biometric badge is the result of R&D activities conducted by(More)
Moving from the innovative principles of the Platform Based Design (PBD) approach for the design of networked embedded systems, the demonstration proposal focuses on presenting the capabilities of a wireless biometric badge, which integrates a localization and tracking service along with an automatic personal identification mechanism, to control the access(More)
Passive tags based on backscattered signals yield low energy consumption for large-scale applications of RFIDs. In this paper, system architectures and protocol enhancements for fast identifications in ISO/IEC 18000-6C systems that integrate UWB technology are investigated. The anti-collision protocol is studied by considering various tag populations. A(More)
Novel and more pervasive healthcare technologies foster an increase in the expectancy of life in next decades. In this field, distributed and networked wireless embedded systems, such as Wireless Sensor Networks (WSNs), suit well with the requirements of ambient care systems, i.e., continuous monitoring of aged or impaired people for their own safety,(More)
