Uma Análise Experimental da Capacidade de Redes Ad Hoc Veiculares

A particular class of vehicular networks is the one that includes off-the-shelf end-user equipments (e.g., laptops and PDAs) running from the interior of vehicles. These equipments are subject to limited communication conditions when compared with nodes specifically designed to this context. In this paper, we investigate through real experiments the characteristics of links formed by nodes within different cars running off-the-shelf wireless technologies. Results show that even without external antennas and using equipments within vehicles, the obtained performance is enough to run typical applications, such as file transfer in peer-to-peer applications. From our results, we identify performance issues and devise configuration recommendations and future work directions. Keywords— IEEE 802.11, Ad hoc networks, Vehicular ad hoc networks.
