Channels
Characteristics for On-Body Mica2Dot Wireless Sensor Networks
[Summary]
Biomedical
applications in Sensor Networks attract many researchers’ focus,
especially in
the real-time health status monitoring field.
However, the inconvenience of interconnecting sensors through
wires not
only induces high maintenance cost also limits freedom of human action. By attaching various types of bio-sensors to
wireless sensor nodes, the unnatural wire constraints have been removed. The sampled data are transmitted through
wireless interface and the system can response in time according to the
different vital signs. Unlike wire
connections, wireless connections are unstable and vulnerable to
environments. It is our goal to study
how the wireless links quality affected by human body, we attached
sensor nodes
onto different parts of human body, and monitor the packets received
rate to
learn how channels behave. We expect these
experiment results can be used to assist the reliable and efficient
connections
for related biomedical researches
