Mobile positioning and

monitoring equipment


Cases: First Responders and Cattle


Equipment with multiple sensors and small
batteries


Need smart energy management to ensure long
operation times

Energy saving approaches
-

examples


Energy cheap accellerometer makes energy expensive GPS
go to sleep when there is no movement


Smart management of sampling rates


when no changes in measurement for some time then lower the
sample rate


When devices are close to each other:


use proximity radio between devices and open only one long
range radio


Location aware routing: send only network packages in the
right direction to reduce communication in the sensornetwork


Assess the trade
-
offs between local computation and sending
data to a remote surrogat computer


Such approaches may also apply for stationary equipment

GreenIP project


Energy and environment management based on
an Internet of Things approach


Utilize the new 6LowPAN standard


IPv6 over Low power Wireless Personal Area Networks


Develop gateway free IP based monitoring and
control systems


No need for Bluetooth, Zigbee gateways


Get places with no power supplies on the net


Embed IP in all sorts of electronic (and mechanic)
building equipment
