A Localization Algorithm of Multi-Hop Three Dimensional AOA with Space-Based Angle Transmission and Its Application of Terrain Modeling
摘要
Abstract
Wireless sensor node's localization is a fundamental technology in Wireless Sensor Networks. Using the idea proposed by representative algorithm-APS multi-hop AOA ( Angle of Arrival) , a new algorithm named MSAT3D AOA Multi-hop Three Dimensional AOA with Space-based Angle Transmission was proposed. By this algorithm , target nodes can use information of anchor nodes which are more than one hop away. The MSAT3D AOA algorithm was also combined with Delaunay triangulation algorithm for terrain modeling. The results of simulation have shown that as the ratio of beacon nodes and their communication radius changes, MSAT3D AOA's localization error rate range from 7% to 27% , that is nearly 30% lower comparing with DV-Hop. At the same time,the proposed algorithm has a good terrain modeling accuracy,range from 59% to 98% ,and a good terrain modeling accuracy.关键词
