Dissertação (Mestrado em Ciência da Computação) - Universidade Federal de Goiás, Goiânia, 2016.http://repositorio.bc.ufg.br/tede/handle/tede/6566For the future of cellular networks is estimated a significant increase in the number of connected devices and the bulk data traffic, especially video content. That poses as a challenge for the next generation network. With the rise of new communications paradigm, D2D communication emerge as potential approach for cellular network data offloading, especially when paired with caching solutions within the network. Also, the impact of viral videos could be mitigated by proactively caching the contents being shared on Online Social Networks (OSNs). This work presents a new approach to proactive content cache for D2D-enabled networks, that is aware of users social interaction on OSN’s. Our proposal consists in the combination of user mobile and social informations to find the best located device to cache a content being shared online. Results obtained through simulation show that the proposed approach can improve offload rate, reduce energy consumption and provide a faster content access when compared with other work in literature.application/pdfAcesso AbertoComunicação D2DRedes sociais onlineRedes sociais móveisDescarregamento de dadosRedes 5GD2D communicationOnline social networkMobile social networksOffloading5G NetworkCIENCIA DA COMPUTACAO::SISTEMAS DE COMPUTACAODissertação
