Acesso em:.https://repositorio.ufpa.br/handle/2011/10043Vehicle Ad Hoc Networks (VANETs) offer a wide range of multimedia services ranging from safety and traffic warnings to entertainment and advertising videos. In this context, users can access content through vehicle-to-infrastructure (V2I) communication, which may consider different wireless networks, such as, LTE, Wi-Fi, etc. However, video streaming at a VANET with Quality of Experience (QoE) and Quality of Service (QoS) is a challenging task, due to the high vehicle’s mobility that causes communication failure with the infrastructure. To mitigate such factors, this master’s dissertation presents a handover algorithm that considers QoE, Quality of Service (QoS) and channel quality in heterogeneous networks, known as handover aware of Quality of Service, Experience and Radio (SER). The proposed algorithm considers the Analytic Hierarchy Process (AHP) to adjust the degree of importance of each criteria in choosing the appropriate radio base station that the mobile node must connect to, allowing a more efficient handover decision for video transmission with QoE support. Simulation results show that SER handover delivered videos with QoE 15 % better compared to the algorithms found in the literature.Acesso AbertoHandover (transferência)QoE - Qualidade de experiênciaQoS - Qualidade de serviçoVANET - Redes ad hoc veicularesRedes heterogêneasRedes veicularesQualidade de serviço, experiência e rádio (SER)VANET ( Vehicular ad hoc networks)Heterogeneous networksQoE and QoS-aware handover for vídeo transmission in heterogeneous vehicular networksHandover QoE e QoS para transmissão de vídeo em redes veiculares heterogêneasDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOES::SISTEMAS DE TELECOMUNICACOESREDES E SISTEMAS DISTRIBUÍDOSCOMPUTAÇÃO APLICADA
