The IEEE 802.11P Performance For Dıfferent Packet Length and Arrıval Rate In VANETs

Osman TOKER    ​


The IEEE 802.11p standard uses Enhanced Distributed Channel Access (EDCA) mechanism for the contention-based prioritized Quality of Service (QoS) at the Media Access Control (MAC) layer. The IEEE 802.11p is MAC and physical (PHY) layer standard for Vehicle Ad Hoc Networks (VANETs), which uses the Enhanced Distributed Channel Access Function (EDCAF) to support contention-based prioritized QoS in the MAC layer. VANET aims to provide users with a better, safer and more coordinated approach to their destination. This paper provides an analytical model to compute the performance of the IEEE 802.11p EDCAF for Vehicular Network based on packet size.
