| 摘 要： | 车载自组网(Vehicular Ad hoc Network,VANET)信道建模对车辆间通信具有重要意义。分析了2.4GHz通信频段两车在武汉市内通信实测丢包率数据,提出了信道丢包率模型FVPM(Fresnel theory based VANET Propagation Model),考虑了实际传输中车辆和街道环境对丢包率影响,以及丢包率随距离变化的概率分布。最后的模型检验结果表明,FVPM比经典Two-Ray、Shadowing模型更加准确地描述了VANET信道特征,对VANET信道研究具有借鉴意义。

| Abstract: | The modeling of wireless channel in VANET(Vehicular Ad hoc Network) is important for inter-vehicle communication.The PLR(Packet Loss Rate)that is tested based on the communication between two cars in Wuhan city at 2.4 GHz is analyzed.A Fresnel theory based VANET Propagation Mode(lFVPM)is proposed,in which the effects of vehicles and streets on the quality of wireless signal are described and the probability distribution of packet loss rate with communication distances is involved.The validation of the model... |
