Abstract

Observing the (social) behavior of animals and especially bats
contributes to improved epidemic forecasts and improved protection of
rare or endangered species. For this task, animal-borne sensor nodes are
powerful tools since they allow collecting more information at less
influence to the species compared to traditional radio telemetry.
However, as bats are inherently small vertebrates, a strict weight limit
of 2 g is dictated for attached sensor nodes. To acquire enough data,
the sensor nodes must achieve a runtime of at least two weeks, which
demands a rigorous energy management. As the data transmission is the
most energy hungry task, minimizing the energy demand in this segment is
a key to achieve the desired runtimes. In this paper we present a novel
technique that enables bursts of erasure coded data without sacrificing
reliability (in a wildlife setting). To keep data losses at a minimum,
our approach exploits the characteristics of the erasure channel and
combines encoded packets in smart way. We evaluated this approach
extensively with experiments, field tests and a theoretical analysis.
The results show a decreased energy demand by 30.177 % to 36.951 % while
the data rate is increased up to a factor of 4 at the same time.
