As we know, the energy needed for sensors should be electrical. So the rst step before start to work is to convert environmental energy to electrical one. Inside the node there are dierent components for sensing the area, collecting data and processing the data. So the main dierent part of this kind of nodes, in compare of WSN nodes, is the power part. Once the stored energy reach to a certain amount, the power supply for micro controller and transceiver will start to work. They will continue to work until they have energy, as soon as the energy nish, they stops and energy storage device start to work to save energy again. The other fact should be consider about EH-WSN node is that the available energy can change in dierent nodes. So every node has its own harvesting rate.

利用小波变换，也是利用多分辨率，去除图像的噪声，从而达到了去除噪声的效果。(Using wavelet transform, which uses a multi-resolution, to remove the image noise, so as to achieve the removal of the noise effect.)

Only coding parameters of sound generation model • LPC is an example where parameters are a1, a2, …ak , e(n) • Music instrument parameters: pitch, loudness, timbre, …Frequency Masking: If a tone of a certain frequency and amplitude is present, then other tones or noise of similar frequency cannot be heard by the human ear • the louder tone (masker) makes the softer tone The Masking Threshold is used by the audio encoder to determine the maximum allowable quantization noise at each frequency to minimize noise perceptibility: remove parts of signal that we cannot perceive
