11.4.6.2 Detailed Physical Parameter Characterization
For detailed characterization of the system performance and especially to pinpoint specific behavior
detailed power traces incorporating the variation of the input are of utmost importance. In order
to characterize device variations, but also to understand the interplay of the power supply (battery,
regulated power, and solar) and the system under varying load conditions instrumentation with a
resolution
 samples/s is required. Since such equipment is currently both costly and bulky it is
not feasible to instrument every node in every testbed. Therefore we propose to instrument only a
number of nodes for detailed analysis and automate the process using an interface to CI.
