GeOASDVN: Um protocolo geocast ciente de obstáculos baseado em Redes Veiculares Definidas por Software

Vehicular Ad-hoc Networks (VANETs) are technologies that allow drivers and passengers to use network services in vehicles. The heterogeneity of VANETs, which can use different wireless technologies, represents a challenge for the development of communication protocols. In this context, the Software Defined Vehicular Network (SDVN) paradigm emerges as a promising alternative that allows the creation of flexible and adaptable protocols. Therefore, this paper presents a geocast dissemination protocol that uses environment and vehicle information to intelligently disseminate messages. The results obtained through simulations show that the protocol presents a more efficient behavior than the opponents, both in environments that do not consider constructions (buildings, houses, etc.) or in environments that constructions are considered (realistic).
