In this study, a new semi-Markov process (SMP)-based model is devised to evaluate the IEEE 802.11p enhanced distributed channel access (EDCA) broadcast performance for vehicular safety communication. Differing from existing SMP analytical models, proposed takes virtual collision among various prioritized categories (ACs) inside each vehicle into consideration. Moreover, in contrast Markov chain...

The IEEE WAVE protocol suite is providing communications services to applications in vehicular networks, by way of promising support for two protocol stacks: the Wave Short Message Protocol (WSMP) and IPv6. While WSMP is developed within the IEEE 1609 family of standards, the authors of this memorandum assert, that considerations for IPv6 operation for WAVE are less developed, and several issue...
