Influence of the RTS/CTS in VANET

Abstract

Vehicular Ad hoc Network (VANET) is a new communication paradigm that enables the communication between vehicles moving at high speeds. This kind of communication uses the IEEE 802.11 standard for physical and MAC layer. In order to solve the hidden problem, the IEEE 802.11 uses the RTS/CTS mechanism. Because of the highest mobility in VANET, the RTS/CTS may introduce performance degradation. In this paper, we clarify these effects by studying the influence of this mechanism on the global performance (delay, loss packet...) in terms of bandwidth, packet size... The simulations are done using Ns-2.
