“…With EDCF mechanism, a vehicular node is allowed to start packet transmission only if the channel is idle for Distributed Inter Frame Space (DIFS) duration before the backoff procedure is permitted to resume. A transmitting station must make sure that the medium is idle for this required duration before attempt to do 1453 the transmitting process [4]. Since there is a possibility of stations choosing the same backoff number, they may send the data in same slot which leads to probability of colliding with each other.…”

In this paper, we present a mathematical analysis on the performance and behavior of uniformly distributed and non-uniformly distributed backoff timer based on binomial algorithm by using two standards which is the conventional DSRC and the latest Wi-Fi Direct. DSRC is a well-known technology being considered as the most promising wireless standard in VANET. On the other hand, as the latest wireless networking standard, the potential of Wi-Fi Direct technology should be concerned. We evaluates these standards using uniform and binomial distribution for contention window under mathematical modelling in order to analyze the average throughput and collision probability performance. The results show that binomial distribution in Wi-Fi Direct standard is 7.05% and 97.13% better than uniform distribution, in terms of average throughput and collision probability, respectively. Thus we can defer that Wi-Fi Direct is feasible to be used as an alternative standard since it has been considered as potential competitor of DSRC in VANET.
