Application-Oriented Performance Comparison of 802.11p and LTE-V in a V2V Communication System

摘要

In recent years,the Vehicle-to-Vehicle (V2V) communication system has been considered one of the most promising technologies to build a much safer and more efficient transportation system.Both simulation and field test have been extensively performed to evaluate the performance of the V2V communication system.However,most of the evaluation methods are communication-based,and although in a transportation environment,lack a V2V application-oriented analysis.In this study,we conducted real-world tests and built an application-oriented evaluation model.The experiments were classified into four scenarios:static,following,face 2 face,and crossing vertically,which almost covered all the V2V communication patterns on the road.Under these scenarios,we conducted experiments and built a probability model to evaluate the performance of 802.11p and LTE-V in safety-related applications.Consequently,we found out that improvements are still needed in Non-Line-of-Sight scenarios.
