Covertness of Wireless Sensor Network Based on Time-Reversal Technique

通过建立室内、街道和小树林3种电磁仿真模型来分析基于时间反演技术的无线传感器网络的隐蔽性。首先对基于时间反演技术的无线传感器网络的基本原理进行了介绍,然后对利用MATLAB所构建的电磁仿真模型进行性能分析,主要分析了时间反演技术的时-空聚焦特性对无线传感器网络的隐蔽性性能的提高。

In this paper,the three models for chamber,street and grove are constructed respectively to analyze the performance of the wireless sensor network for information security based on time reversal（TR）technology.First,the theories of the wireless sensor network based on time reversal（TR）technology are introduced.Then the performance of electromagnetic simulation model that is built by MATLAB was analyzed,the main analysis was how the time-space focusing characteristic from time-reversal improve the performance of Wireless sensor networks for information security.
