A research on discrete probability estimate (DPE) localization algorithm in wireless sensor networks

Abstract

This paper, from the law of normal distribution, we try some new methods of data acquisition and processing. Through depth analysis of probability distribution mechanism, this paper presents that we can use the rectangular area to replace the overlap regions. Through rasterization method, a kind of discrete probability estimate localization algorithm is established. In reducing the calculation of the node as far as possible, the new algorithm is easy to understanding and application, which overcome shortcomings of continuous probability distribution algorithm. Experiment results show that the algorithm we proposed in the paper has better location performance, compared with the typical location algorithm.
