Abstract: For content league sensing network because of data type is not consistent cause scattered grain of noise.Put forward a kind of thing for united sensor network of noise filtering scattered adaptive linear weights algorithm, extract league sensing network scattered grain of the noise characteristics parameters for the above parameters for linear transformation, get noise associated characteristic parameters adaptive linear weights, complete content league sensing network spread particulate noise filter.Through the analysis of experimental results, this algorithm can effectively filter content league of sensor network scattered grain of noise.
