Distributed Energy Measurements in WSN Testbeds with a Sensor Node Management Device (SNMD)

In this work we present our Sensor Node Management Device (SNMD). This device is used in our WSN testbed to measure energy consumption of sensor nodes in a distributed fashion and handle management tasks. We sketch the architecture and electrical specifications of our device and show evaluation results. Furthermore, we point out problems when doing distributed measurements and provide a first solution to the problems.
