【摘要】 对山坡地形的无线传感器网络三维DV-Hop定位算法进行了研究。通过理论与仿真对比分析,在山坡地形应用典型三维DV-Hop算法,定位误差很大,且不稳定,不能满足实际应用需求。提出了基于地形改正的三维DV-Hop算法,节点定位精度高,相对无线射程的平均均方差30%左右,且基本不受山坡倾角、通信半径与锚节点比例的影响,完全可以满足实际应用的需求。更多还原

【Abstract】 Wireless sensor networks(WSNs) 3D DV-Hop localization algorithm on hillside is studied.By theory and simulation comparison analysis,application of typical 3D DV-Hop algorithm on hillside can cause large positioning error and unstable,it can not meet the demand of practical application.3D DV-Hop algorithm based on topographic correction is put forward.Node positioning precision is high,average variance of relatively wireless range is about 30 %,and it is not influenced by hillside inclination angle,communication radius and anchor node ratio,and fully meets the needs of practical application.更多还原
