VANET에서 IEEE 802.11p MAC 프로토콜의 성능 분석

초록

Vehicular Ad hoc Network (VANET) is emerging as a potential technology for the Intelligent Transportation System (ITS) to enhance the safety, comfort and efficiency of driving. The IEEE 802.11p/ WAVE is a standard intended to support wireless access in VANETs. The IEEE 802.11p/WAVE MAC needs to provide the reliable broadcast for emergency traffic and high throughput for service traffic as the performance metrics. Accordingly, in this paper we study on the saturation performance of the IEEE 802.11p by using the 2-D Markov chain model. The numerical results show how the network parameters impact the network performance: normalized saturation throughput of service traffic; packet delivery ratio and average delay of emergency traffic.
