Paper presentation at DATE 2014 in March!
The paper CONTEXT AWARE POWER MANAGEMENT FOR MOTION-SENSING BODY AREA NETWORK NODES by Filippo Casamassima, Elisabetta Farella and Luca Benini will be presented at the 17th DATE (Design, Automation and Test in Europe) International conference and exhibition (March 24–28, 2014 in Dresden, Germany). The presentation is scheduled on Wednesday, March 26, 2014 ( 15:30 - room Konferenz 1) in the session 7.3 Low power methods and multicore architectures for mobile health applications
Body Area Networks (BANs) are widely used mainly for healthcare and fitness purposes. In both cases, the lifetime of sensor nodes included in the BAN is a key aspect that may affect the functionality of the whole system. Typical approaches to power management are based on a trade-off between the data rate and the monitoring time. Our work introduces a power management layer capable to opportunistically use data sampled by sensors to detect contextual information such as user activity and adapt the node operating point accordingly. The use of this layer has been demonstrated on a commercial sensor node, increasing its battery lifetime up to a factor of 5.
