The Analysis and Optimization of the VANET Topology

Abstract

Keyword: VANET, Topology, Optimization, Adaptive Abstract: Vehicular Ad-hoc Networks (VANET) is the research focus of ad-hoc network technology in recent years. Due to fast-moving and other properties of Vehicles, it is extremely easy to change the Topology of the VANET, and communication channels of VANET may become unstable. Then the system performance of the VANET drop overall. Based on the VANET Topology features, this paper proposes an adaptive VANAET Topology optimized Method .According to it, all the region of the VANET is divided into several logical spaces adaptively. In logical region, the method make the connection of V2V or V2I more efficient as possible. and between logical regions, it select several key nodes as the center nodes connecting with other logical regions. So it not only can reduce the average Degree distribution a D in and between logical regions but also improve the connection efficiency  of the entire region. Thereby, providing professional traffic advices and emergency communication services for solving traffic congestion.
