Priority and admission control for assuring quality of I2V emergency services in VANETs integrated with Wireless LAN Mesh Networks

In this paper, we introduce a new priority and admission control mechanism for applications in the Vehicular Communication Networks (VCNs). The adopted network architecture integrates Vehicular Ad-hoc Networks (VANETs) based on the standard IEEE 802.11p and Wireless LAN Mesh Networks (WMNs) based on IEEE 802.11s. The proposed scheme is designed to ensure seamless provision of infrastructure-to-vehicle (I2V) emergency services such as video data streaming between content servers and vehicles. Simulation experiments are intensively investigated to evaluate the effectiveness of the proposed priority and admission control mechanisms. The results show that the proposed mechanism minimizes the end-to-end delay and increases the throughput as well as packet delivery ratio (PDR) of the emergency data flow.
