Adaptive Sampling

Definition

Adaptive sampling is a technique used in sensing and data collection that allows for dynamic adjustment of sampling strategies based on real-time data analysis. This method is particularly beneficial in energy-aware applications, where it optimizes resource use by focusing on areas of interest while minimizing unnecessary data collection, thus conserving energy and improving efficiency.
