IEEE 802.11p is an advanced version of 802.11 to add Wireless Access in Vehicular Environments (WAVEs). This includes data exchange between high-speed vehicles and between the vehicles and the roadside infrastructure. In this paper, the authors have compared simulation results for different MAC (Medium Access Control) protocols in 802.11p (vehicular ad hoc networks) to design 802.11p with optimal network throughput. They have analyzed the performance of different MAC protocols in IEEE 802.11p on the basis of mean density of progress by simulating with different values of path loss exponent, mean of Raleigh channel, distance R, probability p and noise W and they will see the performance of Aloha and CSMA protocols. By comparing Aloha and CSMA (Carrier Sense Multiple Access) protocols in a VANET under different channel conditions.
