1. QoS and QoE Aware Routing Protocol for Flying Ad-Hoc Surveillance Networks Using Fuzzy Inference Systems
Abstract The Flying Ad-hoc Network (FANET) networks have often operated in regions that are difficult to reach and have no fixed infrastructure. The use of devices such as Unmanned Aerial Vehicles (UAV) enable aerial networks to be created that are extremely fast, although there are no specific routing protocols for this type of network that can make communi

2. Energy Efficient Clustering in Multi-hop Wireless Sensor Networks Using Differential Evolutionary MOPSO
ABSTRACT The primary challenge in organizing sensor networks is energy efficacy. This requisite for energy efficacy is because sensor nodes capacities are limited and replacing them is not viable. This restriction further decreases network lifetime. Node lifetime varies depending on the requisites expected of its battery. Hence, primary element in constructi

4. UTILIZATION OF DHT IN DISTRIBUTED COMPUTING SYSTEMS / APLICAÇÕES DE DHT EM SISTEMAS DE MPUTAÇÃO DISTRIBUÍDA
P2P architectures are recognized for decentralization and incentive for the cooperation among nodes. These characteristics allow for fault tolerance and resource distribution among the nodes (by replication) to systems based on the P2P architecture. Systems based in P2P networks built using the DHT technique are scalable. Since this architecture is commonly

5. NSINKS: protocolo de roteamento para redes de sensores sem fio em redes com vários sorvedouros / Wireless sensor networks; Routing protocols; Sinalgo simulator
This work describes the operation of NSINKS, a protocol based ont DESRO protocol, that has the feature of working with more than one sink node and allows dynamic route management in a Wireless Sensor Network. A comparison between protocols NSINKS and DESRO was performed, using the Sinalgo simulator, that showed that the use of multiple sink nodes can increas

7. Algoritmo de roteamento Anycast baseado em algoritmos genéticos para redes tolerantes a atrasos e desconexões / Anycast Routing Algorithm Based on Genetic Algorithms for Delay and Disruption Tolerant Networks
DTNs (Delay and Disruption Tolerant Networks) have the potential to interconnect devices and areas of the world that are underserved by traditional networks. The development of these networks can lead to the revolution of the technology information for the population in developing countries which lack infrastructure, especially in remote and rural regions. I

8. PROPOSTAS DE ROTEAMENTO PARA REDES VEICULARES (VANETS) EM AMBIENTES URBANOS / ROUTING PROPOSALS FOR VEHICULAR NETWORKS (VANETS) IN URBAN ENVIRONMENTS
VANETs (Vehicle Ad Hoc NETworks) are a special case of mobile ad hoc networks where vehicles are equiped with wireless communication interfaces. These vehicles may move at high speeds and data transmission in urban scenarios may easily be blocked by buildings and other sort of obstacles. Such factors contribute to make inter-vehicle communication intermitent

11. 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
