针对目前我军使用GPS全球定位系统存在的不足,在对无线传感器网络进行分析的基础上,建立基于蒙特卡罗(Monte Carlo,MCL)的无线传感器网络定位算法模型.分别对MCL、质心和Amorphous 3种算法进行比较,并以蒙特卡罗定位算法为例,研究估计误差与网络参数及算法间的关系.结果表明,MCL算法误差最小.%Aiming at the current shortcomings of military use of global positioning system (GPS), based on analyzing wireless sensor network, establish wireless sensor network positioning algorithm based on Monte Carlo (MCL). Compare MCL algorithm, centroid algorithm, and Amorphous algorithm. Take MCL positioning algorithm as example, research and estimate the relationship among error, network parameter and algorithm. The result shows that MCL algorithm's error is smallest.
