Performance Evaluation of IEEE 1609 WAVE for Vehicular Communications

In Institute of Electrical and Electronics Engineers (IEEE) Standard 1609, it uses IEEE 802.11 Enhanced Distributed Channel Access (EDCA) mechanism to access the channel. IEEE 802.11 EDCA is a new wireless technology for wireless access in the vehicular environment (WAVE). It defines a new supplement to the existing IEEE 802.11 MAC protocol. In IEEE 802.11 EDCA, the aim is providing a quality of service (QoS) support. While the system serves different access categories (ACs), EDCA does not perform well under high load conditions. In order to improve the efficiency, the authors pay attention to the EDCA with transmit opportunity (TXOP) mechanism. The authors first proposed a Markov chain model and studied the behavior. They extend the model to support IEEE 802.11 EDCA and presented a more accurate analysis under nonideal channel environment. The authors also compared it with that without TXOP mechanism under channel error environment.
