Cooperative vehicle is a new paradigm that offers new opportunities for enhancing various vehicle functions through distributed applications. Localization and perception are among the most important functions needed by numerous vehicular applications, ranging from navigation, autonomous driving and active safety. Recently, several work presented new approaches that make the vehicles cooperate through vehicle-to-vehicle communications in order to enhance these functions. The resulting cooperative localization and collective perception applications have been evaluated individually using V2V communications. However, in real-world applications, these cooperative applications will be supported simultaneously, and they will have to share network communication capacity. In this paper, we evaluate the performance that these two applications can expect from V2V communication services supplied by the CBL (Chain-Branch-Leaf) clustering scheme, when they operate simultaneously. The simulation results show the packet delivery ratios and average delays achieved at IP level for both applications regarding various rates of their respective traffic.
