质心

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

该算法对单跳质心算法进行多跳扩展以改善定比率，并加入场强加权去中心化以提高定精度。

Finally experiments indicate that squared cancroid method is better, which is simple and easy implemented and improves the locating precision and the Noise resisting ability.

通实验表，平加权质心法是一种较为理想的细分定法，不仅简单、易于实现，而且具有更高的定精度以及抗噪声的能力。
