The EveryAware SensorBox: a tool for community-based air quality monitoring

Paper Abstract:

In the EU-FP7-funded EveryAware project a SensorBox is built that will be used in community-based air quality monitoring in Belgium, Italy and the UK. It is conceived as a portable multisensor array or “e-nose” using commercially available electrochemical and metal oxide gas sensors that have shown to react to traffic-related pollution. Further tests […]

Community-based urban air quality monitoring with the EveryAware SensorBox

Paper Abstract:

Community-based monitoring (CBM) encompasses different levels of citizens’ participation going from opportunistic sensing to crowd sourcing, participatory data collection and “citizen science”. In the urban environment with its complex physical and social interactions CBM can help in collecting data at a spatial and temporal scale that corresponds best to inhabitants personal environment and […]

Identification of packet exchange patterns based on energy detection: the Bluetooth case

A time-domain recognition of different wireless technologies may be obtained using energy detection. In this work, an energy detector was implemented using the Universal Software Radio Peripheral SDR platform. The energy detector output allows the formation of a packet presence/absence diagram. Experimental results indicate that the observation of Bluetooth packet exchange patterns reveals technology-specific MAC […]
