【摘要】：无线传感器网络(WSNs)已经被广泛应用在工业和军事中,进行目标监测或者追踪感兴趣的事物.然而,无线通信很容易受到外部攻击,攻击者能够通过无线信号定位到数据源节点的位置.相比于幻影路由方案(PSRS),基于夹角的动态路由方案(ADRS)不仅可以保护源节点位置隐私,而且能够很好地提高网络安全周期和端到端数据包延迟.将进一步分析ADRS保护源节点位置隐私的安全性.首先研究角度与安全性之间的量化关系,通过建立数学模型评估ADRS的平均安全周期,并简单分析其安全边界值.进行仿真实验.实验结果表明,随着固定角度的增大,ADRS的平均安全周期也增大;且在不同的源节点与基站距离中,理论结果与仿真结果非常接近.
[Abstract]:Wireless sensor networks (WSNs) have been widely used in industry and military to monitor or track objects of interest.However, wireless communications are vulnerable to external attacks, and attackers can locate data source nodes via wireless signals.Compared with PSRS, the dynamic routing scheme based on angle can not only protect the location privacy of the source node, but also improve the network security cycle and end-to-end packet delay.The security of ADRS to protect source node location privacy will be further analyzed.Firstly, the quantitative relationship between angle and security is studied, and the average security period of ADRS is evaluated by establishing a mathematical model, and its security boundary value is simply analyzed.The simulation experiment is carried out.The experimental results show that the average security period of ADRS increases with the increase of the fixed angle, and the theoretical results are very close to the simulation results in different distance between the source node and the base station.
