摘　　要：信标节点在无线传感器网络定位算法中起着关键作用,然而信标节点的安全常常被忽视。针对恶意信标节点发送虚假位置信息这种较常见且破坏性较强的攻击方式,在DV-Hop定位算法的基础上提出了一种抵抗恶意信标的安全DV-Hop定位算法。该算法利用信标之间的距离约束来隔离恶意信标节点,同时采用多信标校正值权衡的策略克服了信标比例下降与残余恶意信标对定位结果带来的不利影响,提高定位的准确性和安全性。The beacon nodes play a key role in the process of unknown nodes＇ localization in wireless sensor networks＇ localization algorithms. However, the security of beacon nodes is often overlooked. A secure and optimal DV-Hop localization algorithm is proposed against malicious beacon nodes which send false location information in this paper. The proposed algorithm isolates malicious beacon nodes by the scheme of beacon-distance constraint and overcomes negative factor which is caused by the decline of beacon nodes＇ ratio and remaining malicious beacon nodes by the scheme of multi-correction balance. R improves the correction and security performance of localization algorithm.
