| Abstract: | Four kinds of solution 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. |
