Performance study of 802.11p standard in vehicular networks

In this article we show a study on the functioning and performance of the 802.11p protocol which was designed for Ad-Hoc vehicular networks. The assessment scenario of the protocol is a stretch of avenue in Bogota, and simulation is performed on the omnet ++. network simulator. The parameters evaluated were the response of the connection venue, delays in data transfer, data loss and connection feasibility in a noisy environment. A mathematical operation was applied to the data obtained in order to achieve a correct interpretation of them. From the analysis it was concluded that the standard meets the requirements necessary to be implemented in a vehicular network, however a disadvantage is evident when traffic density is low, since each node fails to establish a connection, or if it succeeds the packet loss rate is high.
