如何安全有效的获取节点的信息是目前无线传感器网络研究的一个热点问题。为保证定位的安全性及提高节点的定位精度，在此提出一种新型的抗攻击的安全定位算法，即：投票机制和基于最小均方误差的结合。首先利用投票机制排除恶意信标节点，然后利用基于最小均方误差法对节点定位。仿真结果表明，该算法可有效的排除恶意节点且相对已有的一些定位算法可显著的提高节点的定位精度。

How to obtain the nodes’ information securely and efficiently is one of the important problems in the present wireless sensor networks. To ensure the security of nodes’ localization and to prompt the localization accuracy, we propose an innovative secure localization algorithm against the attacks, which is the combination of a voting technique and a localization algorithm based on the minimum mean square error. First, we use a voting technique to exclude the malicious anchor nodes. We then locate the nodes’ positions by using the localization algorithm which is based on the minimum mean square error. Simulation results show this algorithm can exclude the malicious anchor nodes sufficiently as well as significantly improve the localization accuracy compared with some other localization algorithms at present.
