| Abstract: |
We investigate system-level energy-saving strategies for sensor nodes that use high-bandwidth Blueto oth radio links. We examine various existing proposals for their suitability for an
application scen ario where sensor nodes continuously collect non-time-critical, low-rate data and transmit it to one or more observer nodes. We present a new, custom-tailored energy-saving
algorithm which considerabl y increases a node's lifetime in our application scenario. We compare the energy-per-transmitted-bit ratio of the BTnode platform running our algorithm to values
reported in related work both for BTno des and for Berkeley Motes. |
