| 摘 要： | 本文对无线传感器网络节点定位问题进行了研究，简要介绍了当前节点定位技术的研究现状，并介绍了一种利用交叠环思想定位网络中未知节点的算法ROCRSSI，说明了该算法的不足之处，提出了两种可行的改进方案：FTPL算法和DMEL算法。理论分析和仿真验证证明，两种改进方案在不同空间下较原算法均有较大的改进。

| Abstract: | This paper studies the localization algorithms of wireless sensor networks, introduces the current research status of localization and a localization algorithm using the concept of ring-overlapping. The disadvantage of this algorithm is also pointed out; two possible improvements are given and compared with each other.Through a theoretical analysis and emulation, two proposed algorithms are proved to have higher performance. |

| Keywords: | wireless sensor network localization algorithm ring-overlapping anisotropy |
