Field Test and Performance Improvement in IEEE 802.11p V2R/R2V Environments

摘要

Ever since the emergence of Intelligent Transportation System (ITS), there has been a rapid integration of communications and automotive electronics industry, promoting developments and trends for the new generation of telematics. Apart from the development and standardization of telematics, its field test is however attracting less attention while being a most important aspect of the issue. The purposes of this research are to set up software/field tests and propose possible improvements for IEEE 802.11p standard. Then, obtaining information from software simulation to establish a controllable field for ground tests, and analyzing the indicative parameters of packet loss and latency of Dedicated Short Range Communication (DSRC) telematics system under mobile conditions, to complete a systematic testing procedure, statistics analysis as well as a transceiver design that will improve the transmission performance.
