Abstract :

IEEE 802.11p vehicular network supports various applications with different transmission priorities and QoS requirements. It classifies the access categories into four priority levels to ensure the successful transmission of higher priority traffic compared to lower priority traffic in a vehicle. But the external collision between traffic of same priority from different vehicles is not considered. Based on such consideration, this paper proposes a distributed priority based channel access scheme. In this proposed work, the priority of each vehicle is calculated based on its stature on the road and access category. The proposed approach can ensure successful transmission reducing collision leading to overall throughput improvement.
