Abstract
In this paper we present a novel wireless sensor node design,
called BodyANT. BodyANT has a miniature outline
of 20x10x3mm and reaches almost 5 days of battery operation
when continuously transmitting acceleration data
at 32Hz. We evaluate the performance of BodyANT in an
extensive set of laboratory and naturalistic experiments over
multiple days. Our sensor node implementation showed robust
performance for up to eight simultaneously operating
nodes. We deployed three BodyANT nodes in a study of
daily activities in combination with two further devices, a
heart rate monitor, and a GPS receiver and analysed the network
performance over multiple recording days. The data
loss per sensor node in the experiment was 3.3% on average.
We present and discuss detailed results on data losses per
user activity.
Our results demonstrate the feasibility of using BodyANT
for long-term activity monitoring and recognition applications.
