We address the design and optimization of an energy-efficient lifting-based 2D transform for wireless sensor networks with irregular spatial sampling. The 2D transform is designe...
We present SoftExplorer, a tool to estimate and analyze the power and energy consumption of an algorithm from the C program. The consumption of every loop is analyzed, and the in...
