Abstract: The main application of the VANETS is to provide the routing between the vehicles. During the transmission of data collisions may occur. To avoid the collision problems the Binary Exponential Back off(BEB) Algorithm is proposed. BEB results in a high delay in message transmission, collisions and ultimately wasting the limited accessible data transfer capacity. As every hub needs to get medium access before transmitting a message, in thick systems, the crash likelihood in the Media Access Control (MAC) layer gets to be high when a poor back off calculation is utilized. The Logarithmic calculation proposes some improvements to the back off algorithms that aim to efficiently use the channel and to reduce collisions. The algorithm under study is based on changing the incremental behavior of the back off value. This paper carries out a deeper study and analysis of the logarithmic back off algorithm that uses logarithmic increment instead of exponential extension of window size to eliminate the degrading effect of random number distribution.
