Mac Protocols for Vanet
نویسندگان
چکیده
Two major goals of vehicular ad hoc networks (VANETs) are to improve road safety and to increase transportation efficiency. In order to achieve these goals, a reliable and efficient medium access control (MAC) protocol is required. MAC protocols for VANETs must balance the delivery success rate, delay, throughput, bandwidth utilization, fairness and overhead of the transmitted packets. In this chapter we provide an overview of the characteristics of VANETs that must be considered in developing MAC protocols appropriate for VANETs. We also provide an overview of the current MAC standards for VANETs, in particular IEEE 802.11p and WAVE. We outline several proposed MAC protocols for VANETs and describe how they differ from the standard. Finally, we propose a cluster-based MAC protocol that uses TDMA to reduce collisions and provide fairness among vehicles.

Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...
