Efficient Emergency Communication with Priority-based MAC Model in Large-scale UAV Assisted VANETs

VANETs, a trending technology, handle dynamic monitoring needs of intelligent transmission systems. Recently, very flexible Unmanned Aerial Vehicles (UAV) have been developed cooperatively to communicate between the ground and the air. This research develops priority-based MAC models (ECPM-UAV) for emergency communication in large-scale UAV aided VANETs. This model's main processes include effective system model, MAC model, data scheduling, and performance analysis. These operations boost UAV-assisted VANET performance. This model is implemented in ns2 and calculates average latency, network throughput, data success rate, and energy efficiency to measure network performance. The end result shows that the proposed ECPM-UAV outperforms baseline approaches in data success rate and energy efficiency.
