摘要
分别研究了2种不同确定路径下(SCAN轨迹和HILBERT轨迹)的节点定位性能。通过Enthought Canopy软件仿真试验得到结果表明:和信标的随机移动相比,任何覆盖整个区域的确定的信标移动路径具有明显的优势;当移动信标以小于通讯范围的分辨率遍历节点网络区域时,SCAN路径具有更低的定位误差;当轨迹的分辨率大于通讯范围时,HILBERT轨迹提供的精度明显更高。
Two kinds of determined path( SCAN track and HILBERT track) were studied separately. It’s shown by the Enthought Canopy software simulation results that any definite beacon moving path which covers the entire region has a distinct advantage over the random moving path. When the node network area is traversed by moves beacon with the communication range which is less than the resolution,the SCAN path has a lower localization error. When the track is greater than the resolution of communication range,the HILBERT trajectory provides a higher accuracy significantly.
