Power Profiling of Context Aware Systems: A Contemporary Analysis and Framework for Power Conservation

Table 2

Comparison of power profiling techniques.

Power profiling		Advantage	Disadvantage	Requirements/suitability
Power consumption profiling methods	Model-based	Easy to implement	Affected by model’s accuracy	Suitable at design times
	Real-measurement based	Real time prediction for dynamic power consumption	High overhead for tracking system events	Suitable for process level
Power consumption profiling finesse	Component level	Produce more accurate results	Requires detailed specifications	Suitable for device vendors at design times
	Device level	Easy to implement	Appropriate way	Usage patterns need to be identified
