Abstract
After discussing the drawbacks of localization algorithm for stationary or slow speed target in WSN, new algorithm based on precise propagation time delay measurement is introduced. Mechanisms for time sampling and TOA measuring procedure are described in detail, which make the measurement error equivalent to CPU instruction cycle. The effect of NLoS is considered in location calculation procedure, which leads to the adoption of variance weight method. Through simulation, the localization precision can reaches 10m in LoS environment and 20m for NLoS.
