摘 要: 针对传统DV-HOP定位算法提出了一种新的无线传感器网络(wireless sensor networks,WSN)安全定位算法SDV-HOP,首先加入一种基于对称密码的加密和认证方案来防御伪装攻击;其次针对虫洞攻击和阻塞攻击引入基于安全处理的平均跳距估计算法,通过对跳距的判断和比较筛选出合适的每跳距离值,从而有效地避免虫洞攻击所带来的误差和错误。仿真结果表明:此安全算法不仅具有较高的定位精度,还能够有效防止和抵御外来攻击。

Abstract: For the shortages of conventional DV-HOP localization algorithm, a new secure localization algorithm for wireless sensor network SDV-HOP is proposed in this paper. First, an addition of a symmetric password-based encryption and authentication program has been used to defend against spoofing attacks. Secondly, against the wormhole attacks and block attacks, an average hop distance estimation algorithm based on the safe handling has been introduced. By the judgments and comparison of hop distance, suitable distance value for each hop has been selected, so the errors and mistakes caused by wormhole attacks can be avoided effectively. Simulation results show that the secure algorithm not only has high positioning accuracy but also can effectively prevent and resist external attacks.
