13. AD* :algoritmo de roteamento em redes de sensores baseado em inteligência artificial distribuída
The technological innovations introduced by the progress in the micro-electronics systems and the wireless communications provided the Wireless Sensor Networks (WSN), a wide variety of commercial and military applications. Those WSN possess of dozens to thousands of sensor-node subjects the fail with connection wireless and limited resources (e.g. energy, pr

14. Proposta de arquitetura de medição e estimativa de tráfego em redes DIFFSERV
This work presents a framework for estimating the delay in networks that implements the Differentiated Services QoS methodology. The work considers the use of the Policy Based Network Management (PBNM) model to perform the collection of data from the core and border routers in a DiffServ domain. The architecture is based on the IETF (Internet Engineering Tas

15. Uso dos algoritmos genÃticos para a otimizaÃÃo de rotas de distribuiÃÃo
When the suply chain of medicine logistic is analysed, critical points can be found in the actual model of deliveries to the drugstores, which are the direct clients of the dealer. The clients demand full requests to be delivered on time. In this context, this work starts with the evaluation of the logistic process of the dealer. A field study has been condu

16. PROJETO DE TOPOLOGIAS VIRTUAIS PARA REDES ÓPTICAS MULTISERVIÇO
Optical communication systems have emerged as the best solution for large scale data transport network implementation, providing optical channels with very high bit rates and covering large distances with low error probability. The entire bandwidth of the optical fibers became available with the development of the wavelength division multiplexing (WDM) techn

17. Uma estrategia de roteamento OSPF adaptativo baseado em estimação de banda / An adaptive OSPF routing strategy based on bandwidth estimation
Internet increase and diversity demand "smart" tools that could make possible to routing protocols self-adapt to network current state (its topology and congestion situation). Smart tools, although, can result in great processing and communication overload. This work presents, besides a new adaptive OSPF routing strategy based on bandwidth estimations, a sim

18. Analyzing the effects of asymmetric unicast routes on multicast routing protocols
Different multicast routing protocols construct their distribution trees based on the information obtained from the unicast routing infrastructure. Nevertheless, the design of most of these protocols do not take into account that unicast routes may be asymmetric. Indeed, unicast routes in the Internet are very asymmetric. The effects on the quality of the mu

19. QoSPY an approach for QoS monitoring in diffserv networks.
Emerging applications with strict performance requirements have introduced needs for distinguishing services in computer networks so as to prioritize some applications more important or profitable than others. Actually it is possible to deliver only one service for all kinds of traffic so far, known as Best-effort service. Therefore, some Quality of Service

20. Exploring Issues of Quality of Service in a Next Generation Internet Testbed: A Case Study Using PathMaster
This case study describes a project that explores issues of quality of service (QoS) relevant to the next-generation Internet (NGI), using the PathMaster application in a testbed environment. PathMaster is a prototype computer system that analyzes digitized cell images from cytology specimens and compares those images against an image database, returning a r
