Abstract :
The IEEE 802.11p architecture imposes a demand- ing reliable transmission requirement on both road-side-unit (RSU) and on-board-unit (OBU) in order to provide emergency messages, traffic information, and internet services. The IEEE 802.16e network, which has been designed as a centralized control system to provide the mobile services in a metropolitan area network (MAN), can assist the WAVE network to fulfill the requirement. As all OBUs equip with both IEEE 802.11p and IEEE 802.16 transceivers, the deficiency of the IEEE 802.11p contention-based medium access control protocol can be curbed by using the IEEE 802.16e centralized scheduling scheme. As a solution, we propose a novel scheme, namely coordinated scheduling scheme (CSS), which allows the IEEE 802.11p OBUs to access service channels in a contention-free manner by means of IEEE 802.16 centralized scheduling. As confirmed by the performance evaluation, the proposed CSS can achieve significant throughput improvement, as compared with the IEEE 802.11p standard.
