中文摘要：
安全性作为评估无线传感器网络定位算法性能的主要指标．虽然近年几个安全定位算法从不同程度上解决这一问题，但都存在着不足。针对恶意攻击存在环境下，卫星传感器网络中节点的自定位问题，基于验证点思想提出既能使用不同定位算法，又不需要增加甚至不用锚点的高质量安全定位协议-SIJPVN-LA。SLPVN-LA利用各节点的定位误差服从相同概率分布且相互独立的性质，结合验证点思想和某种定位算法实现节点安全定位。基于MMSE定位算法的协议性能仿真表明，算法可以有效克服恶意锚点的影响。
英文摘要：
Security as mostly index of evaluating performance of localization arithmetic for wireless sensor networks, although several secure localization algorithms resolve this problem to different degree there still exists some shortage. For solving the self-positioning of nodes in sensor network （SN） on the environment with malicious at- tacks, one protocols is presented which do not increase the number of beacon as well as perfect hardware based on the thought of validation node--SLPVN-LA. SLPVN-LA realizes the localization by using dynamic validation node combining some kind of localization algorithm mechanism. Secure analysis and simulation of protocol performance based on MMSE localization algorithm show that the protocol not only overcomes the infection of vicious beacon but also has good resistance ability against some known attacks.
