摘要
有关时间同步的文献,以及作者之前的研究工作,均表明基于卡尔曼滤波的IEEE 1588PTP在单跳时间同步中有很高的同步精度和稳定性。在OMNet++仿真平台上,验证了基于卡尔曼滤波的IEEE 1588PTP在多跳无线传感器网络中的性能,仿真结果表明:在多跳无线传感器网络中,相比于无卡尔曼滤波伺服的IEEE 1588PTP,基于卡尔曼滤波的IEEE 1588PTP有更高的同步精度和稳定性,更少的误差传递性,此外,对不同时钟的性能分析也表明:基于卡尔曼滤波的IEEE 1588PTP在真实的无线传感器网络中有更好的适应性能。
Literature on time synchronization,including our research work,show that IEEE 1588 PTP based on Kalman filter has high precision and stability of synchronization in peer to peer wireless sensor networks（WSNs）.To validate the performance of the IEEE 1588 PTP based on Kalman filter in multi-hop WSNs simulated by OMNet＋＋.The result show that,IEEE 1588 PTP based on Kalman filter has higher precision and stability of synchronization,smaller transitivity of synchronization error in multi-hop WSNs,compared with IEEE 1588 PTP without Kalman filter.Furthermore,the performance analyses of different node clocks shows that IEEE 1588 PTP based on Kalman filter has better adaptability for real WSNs.
