| 摘要: |
| 时间同步协议是无线传感器网络的重要组成部分,许多无线传感器网络的应用和通信协议都是建立在准确同步的基础之上的.以往的无线传感器网络时间同步协议专注于如何提高同步时间的精确性和减少相关的能量消耗,而现在无线传感器网络时间同步协议的安全问题越来越受到人们的重视.在对无线传感器网络时间同步协议受到的攻击类型进行分析的基础上,利用随机加权平均算法设计了一种具有容错能力的新型无线传感器网络时间同步协议——FTTSP(fault-tolerant time synchronization protocol).仿真结果表明,该协议具有良好的入侵检测能力和对恶意同步信息的容错能力. |

| Abstract: |
| Time synchronization protocol is an important part of wireless sensor networks. Many applications and communication protocols of wireless sensor networks are built on the basis of an accurate synchronized timing. The previous time synchronization protocol for wireless sensor networks focuses on how to improve the accuracy and reduce related energy consumption, but now the security problem of time synchronization protocol in wireless sensor networks is catching people’s attention. This paper designs a new fault-tolerant time synchronization protocol (FTTSP) for wireless sensor networks with random weighting estimation, based on the analysis for the attack to time synchronization protocol for wireless sensor networks. Simulation results show that the protocol has good intrusion detection capability and fault tolerance to malicious synchronization information. |
