| 摘要： | Researchers performed a system level technical study of physical layer and network layer performance of vehicular communication in a specially licensed Dedicated Short Range Communication (DSRC) 5.9 GHz frequency band. Physical layer analysis provides complete understanding of OFDM based 802.11p performance parameterized by packet length, modulation type, vehicular channels and signal-to-noise ratio. Network level analysis of co-channel and adjacent channel interference, using detailed NS-2 simulation model, takes into account impact of collisions and access protocol on QoS and packet delivery ratios. Simulations considered large set of traffic scenarios and characterized the required power levels to achieve given transmission range. Lastly, the feasibility study of practical cooperative localization algorithms for robust prediction and avoidance of accidents is presented. |
