Delouille, "Distributed Wavelet Transform for Irregular Sensor Network Grids," 2005.https://hdl.handle.net/1911/20420Conference PaperWavelet-based distributed data processing holds much promise for sensor networks; however, irregular sensor node placement precludes the direct application of standard wavelet techniques. In this paper, we develop a new distributed wavelet transform based on lifting that takes into account irregular sampling and provides a piecewise-planar multiresolution representation of the sensed data. We develop the transform theory; outline how to implement it in a multi-hop, wireless sensor network; and illustrate with several simulations. The new transform performs on par with conventional wavelet methods in a head-to-head comparison on a regular grid of sensor nodes.engdistributed wavelet transformirregular grid wavelet analysissensor networksWavelet based Signal/Image ProcessingConference paperdistributed wavelet transformirregular grid wavelet analysissensor networkshttp://dx.doi.org/10.1109/SSP.2005.1628777
