Abstract:
Inter-vehicle communication (IVC), which will play an important role in applications such as driving safety support system via periodical exchange of position and speed information among vehicles and autonomous driving which relies on local distribution of road and traffic information, has attracted much attention recently. But IVC does not scale well with the number of requests in the request/response-based communication. In this paper, we propose to apply the technique of Content Centric Network (CCN) to solve this problem, by a cross-layer design, which combines relay vehicle selection, packet forwarding, and cache search, in the same framework. First, we study 1) unique content naming and 2) robust routing (relay vehicle selection, packet forwarding and cache search) to realize the basic function of CCN. Next, we extend the routing method so as to overcome the cache miss problem in the mobile environment. Extensive simulation evaluations confirm the effectiveness of the proposed methods. Compared with the method without caching, the basic method effectively improves system performance. By mitigating the cache miss problem, the extended method (ECCN-IVC) further reduces the average hop count of data packets by up to 46%, and improves the content acquisition success rate by up to 204%.
