1.European countries were trying to decentralize and devolve.

1.欧洲国家尝试着分权和移交权力。

2.The proposed algorithm improves localized nodes ratio by multihop centroid calculating，and improves localization accuracy by decentralizing process and signal strength-weighting process.

2.该算法质心算法进行多以改善定位比率，并加入场强加权过程和去中心化过程以提高定位精度。
