1. Uma abordagem complementar à tradução de endereços para conectividade transparente
Traditional NAT is an extremely common technique, employed on routers in order to share on single Internet connection among many computers of a local network. This technique has been responsible for the survival of IPv4 with its limited address space, and is virtually transparent to many of the Internet application: those that uses the classic client-server

2. Um esquema de seleção de rotas para o balanceamento de segurança e desempenho em redes em malha sem fio / Um Esquema de Seleção de Rotas para o Balanceamento de Segurança e Desempenho em Redes em Malha Sem Fio
Wireless mesh networks (WMNs) have been used to support multimedia applications on different domains, such as health care and entertainment, that require high levels of security and performance simultaneously. Those networks comprise of a wireless backbone of routers that cooperate to provide data communication among mobile devices, such as notebooks, PDAs a

3. Métodos de teste de redes-em-chip (NoCs)
Este trabalho tem como objetivo estudar e propor métodos de teste funcional visando a detecção e localização de falhas na infra-estrutura das redes-em-chip. Para isso, o trabalho apresenta, inicialmente, uma descrição das principais características das redes-em-chip, explicando o que elas são e para que elas servem. Em seguida são apresentados conc

4. Algoritmos genéticos multiobjetivos aplicados ao roteamento multicast com qualidade de serviço
Multicast Routing is an effective way to communicate between multiple routers into computer networks. In general, the quality of service (QoS) is required in most of multicast applications. Several researchers have investigated the application of genetic algorithms in multicast Routing with QoS restrictions. The evolutionary environments proposed in this dis

5. DISCIPLINA DE SERVIÇO BASEADA NA SATISFAÇÃO MEDIDA POR MÉTRICAS DE QOS / QUEUING SCHEDULING DISCIPLINE BASED ON USER¿S SATISFACTION MEASURED BY QOS METRICS
Packet-switched networks have recently replaced circuit-switched networks unifying the way voice and data are carried through those networks. Due to such a new switching concept, challenges related to new applications with different quality requirements have arisen and attracted much attention of computer network researchers. Among the mechanisms used to pro

6. Algorithms for wire length improvement of VLSI circuits with concern to critical paths / Algorítmos para redução do comprimento dos fios de circuitos VLSI considerando caminhos críticos
Esta tese objetiva propor algorítmos para a redução do tamanho dos fios em circuitos VLSI considerando elementos críticos dos circuitos. O problema é abordado em duas perspectivas diferentes: posicionamento e roteamento. Na abordagem de posicionamento, a tese explora métodos para realizar posicionamento de um tipo particular de circuito VLSI, que são

7. Uma arquitetura para otimização do acesso em redes em malha sem fio
Wireless mesh networks are dynamically self-organized and self-configured, with the nodes in the network automatically establishing and maintaining mesh connectivity among themselves. Wireless mesh networks consist of three types of nodes: clients, routers and gateways. Routers have minimal or no mobility. Routers form the backbone of mesh networks. Multi-ho

8. Uma alternativa a inundação baseada em tabelas de dispersão para planos de controle de redes opticas / A hash table based flooding alternative for optical networks control plane
The transport layer structure of the Internet is moving towards a model of highspeed routers interconnected by intelligent optical core networks. A consensus has been reached on wavelength division multiplexing (WDM) as the way to increase the transmission capacity. However there are few proposals for distributed control planes under dynamic Quality of Servi

9. Análise comparativa das instituições e organizações agroindustriais citrícolas dos estados da Flórida (EUA) e São Paulo (Brasil)
Starting with citrus introduction in both Americas, citrus agro industry system installed in Florida (USA) and São Paulo (Brazil) suffered deep changes during growth and evolution processes. Changes caused by new technologies and unexpected events shaped the structure of these systems. Differences of cultural characteristics and habits of each region influe

10. Proposta de um modelo de confiança para o protocolo OLSR
This work presents a new computational trust model, developed to improve the packets forwarding in MANET using OLSR protocol. Mobile Ad hoc Networks (MANET) are composed of mobile devices that communicate directly without the need of any prior infrastructure. The nodes in these networks operate as routers. The Optimized Link State Routing Protocol (OLSR) is

11. VXDL: A LANGUAGE FOR INTERCONNECTION AND RESOURCES SPECIFICATION IN VIRTUAL GRIDS / VXDL: UMA LINGUAGEM PARA DESCRIÇÃO DE INTERCONEXÕES E RECURSOS EM GRADES VIRTUAIS
Grid computing has been defined as an infrastructure integrator of distributed resources. Although it is already used on a large scale in many areas, this type of computational infrastructure is still an area of active research, with many open questions. Today, new research works investigate the application of resources virtualization techniques to perform t

12. Gerenciamento ativo de filas para o protocolo "High Speed Transmission Control Protocol" em redes com produto banda-atraso elevado / Active queue management High Speed Transmission Control Protocol in high bandwidth-delay networks
The efficient utilization of bandwidth in high speed and large delay networks, called high bandwidth-delay product networks (BDP), has become a major challenge. This is due to adjustments of the Transmission Control Protocol (TCP). The High Speed TCP HSTCP): a TCP variant to high BDP networks, employs more aggressive adjustments, allowing scalable bandwidth
