Wide Transmission of Proxy Cooperative Awareness Messages

Résumé

Recently, autonomous vehicles have become a reality. Most of the research related to autonomous vehicles focuses on the sensors attached to vehicles. However, owing to blind spots, sensors are insufficient for avoiding accidents. Cooperative Intelligent Transport Systems (CITSs) have been introduced to reduce blind spots. These systems wirelessly communicate with other CITS-enabled vehicles and collect road and traffic information. There are two types of messages used in CITS: Cooperative Awareness Messages (CAMs) and Decentralized Environmental Notification Messages (DENMs). CAMs are used to notify the existence of sender. Some issues are known to exist with these messages. Several methods have been proposed to help overcome these issues. One of these methods is Proxy CAM. In this study, we will describe four problems of Proxy CAM and propose Grid Proxy CAM, which builds a network of Proxy CAM devices and forwards Proxy CAM packets. We have been developing two methods for this system. The first is “SDN routing”, which uses Software Defined Network (SDN) for route control. The second is “Passive selection”, which is used to select incoming Proxy CAM packets. Furthermore, we will discuss the advantages and disadvantages of these methods and the future plan of this ongoing work.
