14. 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

15. Otimização multi-objetivo aplicada à alocação dinâmica de rotas em redes de telecomunicações
The new networking technologies and the Internet difusion produced the data traffic increase in the networks. The quality of service (QoS) requirements for applications also increased and become stricter. Different QoS metrics can be evaluated by applications, for example the delay, the load balance and the packets lost in the communication.Different optimiz

18. AnÃlise de atenuaÃÃo de sinal em ambientes indoor usando lÃgica nebulosa / Analysis of signal attenuation for Indoor Environments using Fuzzy Logic
Due to the increasing demand for services related to wireless networks, such as video, voice and video conferencing and to the concern of telecommunications companies to meet this demand efficiently, the planning of a wireless link becomes very important. Since the propagation of a signal over a wireless network is not driven, it can suffer attenuation cause

21. Nodes architecture and traffic engineering in optical networks / Arquitetura de nós e engenharia de tráfego em redes ópticas
Integrating telecommunication networks has enlarged the coverage, but has made operations more complex, mainly because of the architecture, formed by various layers. These layers deal with different protocols and transmission rates, as well as electrical and optical signals. The usual alternative of expanding the resources proportionally to the demand is imp

22. Análise de desempenho de composição de redes em redes de ambiente / PERFORMANCE ANALISYS OF NETWORK COMPOSITION ON AMBIENT NETWORKS
Since the telecommunications scenario become highly diverse, for instance, because of the development of heterogeneous access technologies (like WLAN, WiMAX and UMTS) and new types of networks, it is necessary a uniform procedure for cooperation between these networks. A network composition consists exactly of this uniform and dynamic procedure to achieve co
