摘　　要：针对车载自组网(vehicularad hocnetwork,VANET)拓扑结构速度过慢、处理数据过多,导致信道容易阻塞、实时性差的问题,提出一种基于地理信息和超宽带的小型自组网链路优化算法。利用UWB测距信息和地理信息进行系统设计和理论分析,并搭建基于Matlab的仿真平台。仿真结果表明:基于该优化算法的链路模型在所有可能的链路模型中位于次优或者最优这一档,相对同样物理拓扑结构下其他可能模型,最大时延优化可达25%。Aiming at the problems of vehicular ad hoc network(VANET)topology,such as slow speed,too much data processing,channel blocking and poor real-time performance,a small ad hoc network link optimization algorithm based on geographic information and ultra-wideband(UWB)is proposed.The system design and theoretical analysis are carried out by using UWB ranging information and geographic information,and the simulation platform based on Matlab is built.The simulation results show that the link model based on the optimization algorithm is in the sub-optimal or optimal level among all possible link models,and the maximum delay optimization can reach 25%compared with other possible models under the same physical topology.
