Uma arquitetura para a gerência de mobilidade para redes veiculares com suporte a ambientes virtuais colaborativos

Rodolfo I. MeneguetteEdmundo R. M. Madeira

Information technology and mobile communications are being widelyused in Intelligent Transport System (ITS), through services for vehicle networkswhere the vehicle can interact with other vehicles or with an access point. Giventhe benefits and limitations of each technology, such cell and metropolitan networks,it becomes a challenge to effectively integrate these heterogeneous accessnetworks to provide ubiquitous radio broadcasting services with broad coverageacross the handoff. In this work an architecture for management of intra-andinter-system for wireless networks was developed to virtual environments, supportingcollaborative virtual simulations, that will assist in the rescue or reliefto an accident or even a game. Ns2 simulations were performed to compare theapproaches with and without the 802.21 protocol over the MIPv6, consideringas base stations, Wifi and WiMax networks. As a result of this work we observedthat the mechanism that used the 802.21 protocol had a shorter time of handoffand lower packet loss.
