Resumo: | In this work we present and evaluate a modeling methodology that describes the creation of a topology for wireless mesh networks, and how this topology changes over time. The modeling methodology is based on network science, which is a multidisciplinary research area that has a lot of tools to help in the study and analysis of networks. In wireless mesh networks, the relative importance of the nodes is often related to the topological aspects, and data flow. However, due to the dynamics of the network, the relative importance of the nodes may vary in time. In the context of network science, the concept of centrality metric represents the relative importance of a node in the network. In this work we show also that the current centrality metrics are not able to rank properly the nodes in wireless mesh networks. Then we propose a new metric of centrality that ranks the most important nodes in a wireless mesh network over time. We evaluate our proposal using data from a case study of the proposed modeling methodology and also from real wireless mesh networks, achieving satisfactory performance. The characteristics of our metric make it a useful tool for monitoring dynamic networks. |

A modelagem é baseada em ciência das redes (network science), uma área multidisciplinar de pesquisa que possui uma grande quantidade de ferramentas para auxiliar no estudo e análise de redes. Em redes em malha sem fio, a importância relativa dos nós é frequentemente relacionada a aspectos topológicos e ao fluxo de dados. Entretanto, devido à dinamicidade da rede, a importância relativa de um nó pode variar no tempo. No contexto de ciência de redes, o conceito de métricas de centralidade reflete a importância relativa de um nó na rede. Neste trabalho, mostramos também que as métricas atuais de centralidade não são capazes de classificar de maneira adequada os nós em redes em malha sem fio. Propomos então uma nova métrica de centralidade que classifica os nós mais importantes em uma rede em malha sem fio ao longo do tempo. Avaliamos nossa proposta com dados obtidos de um estudo de caso da modelagem proposta e de redes em malha sem fio reais, obtendo desempenho satisfatório. As características da nossa métrica a tornam uma ferramenta útil para monitoramento de redes dinâmicas.Submitted by Cássia Santos (cassia.bcufg@gmail.com) on 2014-09-11T11:50:01Z No. of bitstreams: 2 Dissertacao Diego Americo Guedes.pdf: 971567 bytes, checksum: a39a61e190ff600e318da0dd24eb108c (MD5) license_rdf: 23148 bytes, checksum: 9da0b6dfac957114c6a7714714b86306 (MD5)Made available in DSpace on 2014-09-11T11:50:01Z (GMT).

| description |
In this work we present and evaluate a modeling methodology that describes the creation of a topology for wireless mesh networks, and how this topology changes over time. The modeling methodology is based on network science, which is a multidisciplinary research area that has a lot of tools to help in the study and analysis of networks. In wireless mesh networks, the relative importance of the nodes is often related to the topological aspects, and data flow. However, due to the dynamics of the network, the relative importance of the nodes may vary in time. In the context of network science, the concept of centrality metric represents the relative importance of a node in the network. In this work we show also that the current centrality metrics are not able to rank properly the nodes in wireless mesh networks. Then we propose a new metric of centrality that ranks the most important nodes in a wireless mesh network over time. We evaluate our proposal using data from a case study of the proposed modeling methodology and also from real wireless mesh networks, achieving satisfactory performance. The characteristics of our metric make it a useful tool for monitoring dynamic networks. |
