Abstract :
A major challenge of Intelligent Transport System (ITS) is the provision of high capacity wireless networking infrastructure to support vehicular communication. In order to understand the basic processes in such networking, in this paper, we provide the measurement results of TCP performance over IEEE802.11n wireless local area network (WLAN). We concentrate our evaluation on multi hop communications in vehicle to infrastructure (V2I) scenario with three wireless access points. The experiment results testify the possibility of using a wireless distribution system (WDS) to connect APs wirelessly extending the transmission range area of network architecture and the connectivity time of the data transmission. Analyzing our results was found that handover is one of the main causes reducing the performance of wireless network.
