1. A Performance Evaluation of WLAN-Femtocell-LTE beyond the Capacity Crunch. Does Femtocell have to overcome WLAN or can they coexist in HetNets?
Abstract This paper originates from a practical experiment based on Mesh Networks. The promising results obtained from this experiment prompted us to discuss in greater depth whether Wireless Local Area Networks (WLAN) are still useful for current communications. This means that on the one hand femtocells can be defined as small base stations that use the sa

2. Wi-Bio: management policy aimed at the establishment of networks for patient monitoring using IEEE 802.11
INTRODUCTION: Patient monitoring will tend to decline in the coming years due to a shortage of physical and human resources in hospitals. Therefore, several studies define alternatives to improve patient monitoring using wireless networks. In these studies, a wireless network is used to transfer data generated by medical sensors without interacting with the

3. AlocaÃÃo de recursos com justiÃa: uma aplicaÃÃo de jogos cooperativos em redes de computadores
This work presents a methology for applying cooperative game theory concepts for solving the bandwidth allocation problem within differentiated traffic profiles for Internet applications. The multi-service networks scenario is explored as an operational network example for fair bandwidth sharing mechanisms. This operational network uses mechanisms based on s

4. Coexistir na fronteira: notas de um antropólogo sobre a trajetória de um grupo de jovens em meio a uma guerra entre a comunidade e o tráfico de drogas
On behalf of an anthropology that looks for to analyze the can-resistance relationships starting from the coexistence among the several components inside of different urban territories and that he seeks to do to emerge the several present violence forms in the daily relationships is that I intended to accomplish this research. In my entitled research of Mast

5. Avaliação de desempenho do protocolo MIPv6 utilizando a rede de telecomunicação aeronáutica (ATN). / Evaluation of performance of protocol MIPv6 using the aeronautical telecommunicaton networking (ATN).
Currently the use of standard IPS (Internet Protocol Suite) in the ATN it comprehends the concepts of IP mobility, convergence in the air-to-ground communication and also ATN sub-nets in land. The ICAO (International Civil Aviation Organization) mentions the ATN/IPS, which is based on connections supported by TCP and UDP protocols in the transport layer and

6. Automatic dependent surveillance on air traffic control: risk assessment based on fluid stochastic Petri nets modeling. / Vigilância dependente automática no controle de tráfego aéreo: avaliação de risco baseada em modelagem em redes de Petri fluidas e estocásticas.
In last decades, the safety critical systems paradigm has changing to adapt itself to new necessities, such as costs reduction and productivity demand growth. In the Air Traffic System, those changes are ruled by CNS/ATM paradigm (Communication, Navigation, Surveillance / Air Traffic Management), based on new digital Technologies, mainly Satellites, applied

7. Risk analysis of the airborne time-based spacing operation through a stochastically and dinamiclly coloured Petri net model. / Análise de risco da operação de espaçamento temporal aerotransportado por meio de um modelo em rede de Petri estocástica e dinamicamente colorida.
The safety in the airspace can considerably increase with the use of airborne spacing and separation operations. Under this paradigm, the task of maintaining a safe distance between aircraft is delegated to the pilots, which will be supported by the Airborne Separation Assistance System (ASAS). With this system, which is still in experimental phase, pilots b

8. AvaliaÃÃo da qualidade de vÃdeo trafegando sobre redes IP / Evaluation of the quality of video passing through on nets IP
O uso das redes de computadores, em especial redes IP, jà à realidade para distribuiÃÃo e troca de conteÃdo multimÃdia. Oferecem, dada sua capilaridade, uma opÃÃo econÃmica inclusive para a contribuiÃÃo e distribuiÃÃo de vÃdeo de emissoras e redes de televisÃo. No entanto, o material de vÃdeo e Ãudio apresenta normalmente caracterÃsticas de

9. Analysis of optic nets without commutation using the method of the random traffic equivalent. / Análise de redes ópticas sem comutação usando o método do tráfego aleatório equivalente.
O objetivo deste trabalho é utilizar o método do tráfego aleatório equivalente para analisar e dimensionar redes ópticas sem comutação para arquitetura de nível único. Uma modelagem analítica, baseada nesse método, que possibilita otimizar os parâmetros da rede considerando padrões mínimos de desempenho é descrita. A rede em estudo utiliza ape

10. VIDEO CONNECTIONS ADMISSION REGIONS WITH TIME DEPENDENCE / CONTROLE DE ADMISSÃO DE CONEXÕES DE VÍDEO COM DEPENDÊNCIA TEMPORAL
The presence of time dependence on different types of connections has motivated new traffic engineering research. In this dissertation, we examined the impact of this time dependence on the video connections admission regions. We considered several video sequences with different dependence degrees or Hurst parameters. For Hurst estimation, we developed a sof
