WSN技术在空间定位系统中的应用

The application of WSN technology in the space location system

通过应用无线传感器网络(WSN)技术,应用随机数定位算法向大家展示了一种低能耗的基于WSN技术的空间定位系统,使得对佩带了WSN节点(mote)的人可以实时的定位。在本系统中,通过使用基于取样的表示方法,我们的定位算法能够表示任意的分布。最后,通过仿真对比,我们发现,使用本系统获得的人的运动轨迹与真实的运动轨迹非常接近,并且定位错误的发生对采样数的依赖不是很明显。

This paper presents a low energy cost space location system based on WSN technology and random sampling algorithm, whieh can locate a person holding a WSN mote in real situation. In this system, by using the representation based on random sampling, our location algorithm can represent arbitrary, distribution. According to the comparison of the simulation, we conclude that the movement trajectory acquired by this system is similar to the real movement trajectory, and the number of location errors does not rely on the number of sampling numbers obviously.
