  22. 22. Torsten Braun: On Hardware and Software Approaches to Monitor Wireless Mesh and Sensor Networks Conclusions > High energy costs by wireless network interfaces (UMTS, WiFi) > Hardware for energy / battery measurements — is available and very valuable for studying details and providing data for software-based measurements and simulation models (require accurate calibration and modelling) — can be learned by CS students/researchers — comes sometimes with high costs and does not scale > Better integrated (hardware/software) support for energy consumption profiling in mesh and sensor nodes desired.
