Performance comparison of IEEE 1609.4/802.11p and 802.11e with EDCA implementation in MAC sublayer

Abstract

One of the most challenging issues in IEEE 1609.4 is the assurance of Quality of Service (QoS), i.e. to improve throughput and reduce delay in the sublayer Medium Access Control (MAC) IEEE 1609.4. The prioritization of each service package, using Enhanced Distributed Channel Access (EDCA) at the MAC sublayer is designed based on the IEEE 802.11e with some modifications to the transmission parameters.
