Design and development of the experiment system for a vehicle Ad hoc network

This paper proposes an information description architecture named multi-dimensional and multi-layer, in which equipments in each vehicle that are possible to access to the network are considered as “elements” in n×m order matrix. Then a positioning algorithm, UKF, using multi-dimensional and multi-layer information is proposed, which increases the positioning accuracy greatly. Furthermore, in order to verify the architecture and algorithms proposed in this paper, an experimental system is developed. Experimental system is tested in different vehicle movement modes at several places. The results show that the experimental system runs steadily and achieves expected target.
