一种VANET信道丢包率模型
Packet loss based channel model for VANET
摘要
Abstract
The modeling of wireless channel in VANET(Vehicular Ad hoc Netwoik) is important for inter-vehicle communicatioa 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 Model(FVPM) 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 shows it describes the channel of VANET more accurately than Two-Ray and Shadowing models.关键词
