Abstract
Vehicle-to-infrastructure (V2I) communication based on wireless local area network (WLAN) technology can provide users in-motion to obtain Internet connectivity. In this paper we present an experimental study of IEEE802.11n with diminished settings compared to the legacy system using off-the-shelf devices in V2I small scale scenario. In order to evaluate the V2I the 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 Markov process.

Highlights
The urgent need for the diminishing of road traffic accidents, traffic jams, CO2 emission and environmental impact are a major challenge for academics and industry
It is highly desirable to obtain a mathematical description of process with real data from small scale scenarios of practical measurement results and perform an evaluation prior conducting field trials as it is made in this work
Off-the-shelf laptop with wireless local area network (WLAN) based on IEEE802.11n standard was used as a mobile user’s device without external antenna and the similar laptop for fixed station is wired to an off-the-shelf WLAN access point (AP) (ASUS RTN16)
Summary
The urgent need for the diminishing of road traffic accidents, traffic jams, CO2 emission and environmental impact are a major challenge for academics and industry. Result from common effort is an international standard, IEEE802.11p [1] with raw data rate up to 27Mbps This standard is able to provide a short message communication to enhance safety on the road and traffic flow, but it does not have the capacity to ensure the comfort of the passengers and drivers with appropriate INTERNET access. Realizing field trials for goodput evaluation of vehicular wireless communication systems is very difficult and costly because many vehicles and communication equipment need to be purchased or rented, and many experimenters need to be employed Given such problems, it is highly desirable to obtain a mathematical description of process with real data from small scale scenarios of practical measurement results and perform an evaluation prior conducting field trials as it is made in this work.
