Due to the mobile nature of nodes comprising the vehicular networks in addition to interference and congested network traffic, the design of an efficient MAC network becomes challenging. Moreover, the latency constraints underlying safety application add complexity to this design. The TXOP (Transmit Opportunity) mechanism defined in the IEEE 802.11e is optimized to meet the requirements of a Multimedia...
One of the most challenging issues facing vehicular networks lies in the design of an efficient MAC protocol adaptable to different traffic scenarios (urban and suburban environments). While each environment has its own characteristics leading to different challenges, the merit of this paper lies in developing a MAC protocol suitable for both. In this work, we propose an efficient Multichannel QoS...
