秸秆焚烧定位系统中的DV-Hop算法的改进
Improved DV-Hop algorithm in positioning system of straw burning
摘要
Abstract
Straw burning can cause serious air contamination and endanger human health. It is very important to get accurate position information of the burning straw timely. It requires very high positioning accuracy. The traditional DV-Hop algo-rithm positioning error is large. The burning of straw positioning system adopts an improved DV-Hop algorithm based on minimum mean-square error criterion so that it can effectively improve the location accuracy. It is divided into two areas, one is to use the mean square error method to solve the average hop distance, another one is to use the weighted average method to calculate the weighted average distance after using the traditional method to calculate the average distance of each hop. The improved algorithm's positioning precision is much higher than the before in the same reference nodes environment by the MATLAB simulation test.关键词
