Experimental Analysis of Wireless Positioning Accuracy for Vehicular Ad Hoc Network Technology Application

摘要: Vehicular ad-hoc networks (VANets) form when vehicles are equipped with devices capable of short-range wireless communication. Accurate positioning VANets is a challenging task, which requires robust algorithm. In this study, the trilateral and quadrilateral algorithms proposed to estimate moving vehicle nodei¯s position in based on signali¯s i°distance-lossi± model geometric relationship. Furthermore, experimental platform was created test algorithm applications field. The field an open area one node four fixed nodes. results show that inside nodes, accuracy much higher than case outside nodes; located middle field, at corner areas field; method has better accuracy.
