Wireless sensor networks becomes a new data collection technology of autonomous sensor nodes. The research on localization algorithm in the actual applications has been very hot. In this situation, a number of excellent localization algorithm appeared according to various factors, such as the cost, power and applications areas. As we know, the anchor-based mass algorithm has higher precision while the anchor-free ABC algorithm has lower cost. In order to take advantages of them, a new localization algorithm is presented. It does not only control the precision within endure ranges of ABC algorithm, but also reduces the number of anchors of the mass algorithm. So it can meet the needs of the actual applications. Finally, the attentions of the new localization algorithm is indicated.
