Applying the classical graph drawing algorithms to node localization in wireless sensor networks is a novel idea.

将经典的画图算法应用到无线传感器网络节点定位问题是一个全新的思路。

The characters of the new method are: the structures of the different graph drawing algorithms are the same, the difference exists only in the objective functions which reflect aesthetic criteria.

新方法的特点是：不同的画图算法的框架都一样，所不同的只是反映无向图画图问题的美观标准的目标函数。
