Performance Evaluation and Analysis of Three Kind of Distance Estimation Method Based on Chinese Remainder Theorem

对目前已有的4种中国剩余定理的求解方法,即传统中国剩余定理算法、闭式解的中国剩余定理算法、高效中国剩余定理算法以及多频中国剩余定理算法,进行了较详细的理论分析与性能比较。将上述算法应用于无线传感与激励网络中对未知节点进行测距,设计了相应的测距算法,分析了各算法的性能特点,并通过仿真实验分析比较了各自在估计精度、计算复杂度以及鲁棒性等方面的差异,并讨论了各算法的适用场景。

Four kinds of mlution method of Chinese Remainder Theorem（CRT） which are known as Traditional CRT, Efficient CRT, Closed-Form CRT and Dual-Frequency CRT were studied and analyzed. And then that four kinds of CRT were used in distance estimation in wireless sensor and actor networks（WSANs）. Four distance estimation methods were designed based on the four kinds of CRT and the characteristic of the four methods were analyzed. The difference at estimation precision, complexity and robustness was compared based on simulations and the scenarios where each method is applicable were point out.
