In particular, we start studying the random networks which characterize or are related to some real situations, for instance the tide movement. In this context of complex networks, we investigate several real networks, as well as we define some important concepts in the network studies. Furthermore, we present the first scale-free network model, which was proposed by Barabási et al., and a modified model studied by Bianconi and Barabási, where now the preferential attachment incorporates the different ability (fitness) of the nodes to compete for links. At the end, our results, discussions and conclusions are presentedapplication/pdfAcesso AbertoRedes complexasModelo de qualidadeRedes livre de escalamasterThesisCNPQ::CIENCIAS EXATAS E DA TERRA::FISICA
