Vehicular Networks
Slides presented at the XX Jornadas de Paralelismo.
Currently wireless communications have been significantly improved, being widely used in various areas such as health, education, industry and research. Recently, the automobile industry is adopting wireless technologies in order to improve the services offered, such as safety, traffic updates and infotainment. In particular, vehicular ad-hoc networks are being promoted to improve safety on the road. In this paper we provide a performance evaluation of a content delivery framework over VANETs to assess the viability of this type of schemes. In our experiments we vary several parameters, such as vehicular density, speed, and content demand rate under different environment conditions to evaluate, from a cross layer perspective, the impact they have on metrics such as delivery latency, routing overhead, throughput, and packet loss; in particular, we evaluate user satisfaction through the latency perceived and the network performance via the packet loss. Results show that, despite of the routing overhead generated, the overall performance is improved when speed and vehicular density increase.
