Vehicle-to-infrastructure communication based on 802.11n wireless local area network technology

摘要

Vehicle-to-infrastructure (V2I) communication based on wireless local area network (WLAN) technology can support highly mobile users to obtain Internet connectivity. Wireless access for the vehicular environment (i.e. IEEE802.11p) provides the required principal standardization for vehicle-to-vehicle V2V solution and supported raw data rate up to 27 Mbps. This standard mainly is oriented on urgent short message transmission. Otherwise, for transmission of large amount of data, for instance file transmission for Internet, alternative solutions may be proposed. In this paper we present an experimental study of IEEE802.11n with diminished settings compared to the legacy system (i.e. IEEE802.11g) using off-the-shelf devices in vehicle-to-infrastructure scenario. In order to evaluate V2I type of communication in the large scale scenario, in this paper we propose an analytic model to characterize the goodput of WLAN-based networks using Buzen's method and Markov process.
