Controle de qualidade para 3D-vídeo streaming em redes em malha sem fio

Abstract

Wireless Mesh Networks (WMNs) are envisaged to be one of the most important wireless technologies to provide last mile access in future wireless multimedia networks. In this context, 3D-video is envisioned to attract more and more the multimedia market with the perspective for enhanced applications (video surveillance, mission critical control, entertainment, etc.). However, the challenge of dealing with the uctuating bandwidth, scarce resources and time-varying error rate of these networks, illustrates the need for error-resilient 3D-video transmission. In this context, Forward Error Correction (FEC) approaches are required to provide the distribution of video applications for wireless users with Quality of Service (QoS) and Quality of Experience (QoE) assurance. This study proposal puts forward a FEC-based mechanism with Unequal Error Protection (UEP) to enhance 3D-video transmission in WMNs, while increasing user satisfaction and improving the usage of wireless resources. The benefits and impact of the proposed mechanism will be demonstrated by using simulation, the assessment will be conducted with objective and subjective QoE metrics.
