Embedded energy emulation and monitoring in WSNs

In spite of the availability of accurate models to estimate and simulate the power consumption of all the components of a WSN in all possible operating modes, it is very hard to capture the effect on power consumption of runtime phenomena like overhearing and packet losses possibly caused by interference among nodes and environmental conditions. At the same time, it is very hard to make in-field measurements of the actual consumption of each node of a large WSN, while also monitoring its workload.
These issues become even more challenging when dealing with energy harvesting WSNs that are powered by time varying energy sources. We present embedded energy monitoring and emulation as a viable solution to instrument large scale testbeds.
We outline the HW-SW architecture of the proposed solution and we present preliminary experimental results.
