As redes móveis heterogêneas já são realidade e sua densificação tem sido apontada como uma das soluções propostas para atendimento das demandas esperadas para as redes celulares de quinta geração (5G). Nas redes atuais, no entanto, ainda é comum o uso de parâmetros fixos na configuração da rede, mas esta estratégia nem sempre se mostra eficiente. É dentro deste contexto que se consolida o conceito de redes auto organizáveis nas quais os vários parâmetros da rede são ajustados automaticamente com base em medições em tempo real e sistemas inteligentes. Esta tese apresenta uma estratégia para otimização de handover em redes LTE com densa implantação de small cells. Com base em medições e lógica fuzzy são propostos algoritmos para o auto ajuste de parâmetros da rede. A partir de simulação discreta utilizando o MATLAB, os resultados são obtidos e apresentados através das principais métricas de avalição de desempenho de handover. / The increase in mobile devices and applications in recent years has led to an overload of the network infrastructure responsible for disposing this traffic, thus affecting the performance of the network as the user experience.Heterogeneous mobile networks are already a reality and their densification has been put forward as one of the suggested solutions to meet the expected demands for 5th generation (5G) mobile networks. However, in the current networks, it is still common for fixed parameters to be used for the configuration of the network although this strategy does not always prove to be efficient. It is within this context that the concept of selforganizing networks (SONs) has been established, in which several network parameters are automatically adjusted on the basis of measurements and intelligent systems in real time. This thesis presents a strategy to optimize the handover in LTE networks with dense small cells. Based on measurements and fuzzy logic new algorithms are proposed for self-tuning network parameters. From discrete simulation using MATLAB, the results are evaluated and presented through the main performance metrics of handover.

Healthcare delivery within the military requires a multifaceted approach to achieve the desired outcomes of safe, effective, patient-centered, timely, efficient, and equitable health care. The prospect of maintaining a cycle of continuous process improvements within military clinical settings hinge on frontline leaders and middle-level managers who must be prepared to execute the mission and motivate, supervise, coach and mentor the staff. This project showcases a review of current literature translated into the development of an evidence-based Transformational Leadership Induction Program (TLIP) module that consisted of 4 subsections: the environment of care, clinical decision support systems, human resources management, and change management as well as resources for successful leadership within the organization. The training is designed to bridge the transition gap, facilitate role orientation and induction, and socialize frontline and middle-level managers during their role transition. The results of a need assessment survey, approved by the organization, were completed by 30 incumbents and resulted in 57% (17) providing feedback and role-specific contents that were integrated into the development of the TLIP module. The overall response to the survey was positive with 82% (14) of the respondents either agreeing or strongly agreeing with the items that they reviewed. The TLIP module provides a medium that translates current evidence into a succinct training platform capable of enhancing leadership transition and handoff. The TLIP module enables a culture of trust, enhances staff satisfaction, and fosters change management and succession planning within the military healthcare system.

Aujourd'hui, les utilisateurs mobiles intègrent plusieurs interfaces sans fil dans leurs dispositifs mobiles, tels que IEEE 802.11, des technologies cellulaires 2G/3G/4G, WiMAX ou Bluetooth, car ces technologies hétérogènes peuvent fournir un accès Internet dans les zones urbaines. Dans ce contexte, il existe un potentiel pour les utilisateurs mobiles d'exploiter la diversité des interfaces sans fil, afin d'être connectés aux réseaux de la meilleure manière possible, à tout moment et partout. Cependant, afin de profiter de cette diversité des réseaux il est nécessaire d'avoir une gestion efficace de la mobilité et de la multi-domiciliation. En ce qui concerne la mobilité, les utilisateurs mobiles ont besoin de découvrir les réseaux sans fil et basculer entre des points d'accès d'une façon transparente et sans coupures. Afin de supporter la multi-domiciliation et de permettre l'utilisation de plusieurs réseaux sans fil simultanément, il est nécessaire de définir des mécanismes de sélection des réseaux visant à attribuer les flux d'applications aux différentes inter- faces sans fil d'une manière optimale. Dans cette thèse, nous avons d'abord caractérisé la diversité des réseaux en explorant et en analysant les performances des déploiements sans fil actuelles dans les zones urbaines, en particulier les réseaux cellulaires et les réseaux communautaires basés sur IEEE 802.11. Ensuite, nous avons étudié la mobilité dans les réseaux IEEE 802.11, particulièrement le processus de découverte des points d'accès, en fournissant deux algorithmes adaptatifs qui visent à utiliser les paramètres de découverte les plus appropriés dans chaque scénario. Nous évaluons ces algorithmes par l'expérimentation et nous comparons leurs performances par rapport aux stratégies utilisant des paramètres par défaut. Enfin, nous étudions la sélection des réseaux dans un scénario multi-domicilié et nous proposons un algorithme de prise de décision pour trouver l'attribution optimale des flux aux différentes interfaces, en prenant en compte des critères de qualité de service et de consommation d'énergie. Cet algorithme de décision est modélisé par un problème d'optimisation multi-objectif et est résolu avec des algorithmes génétiques. Nous évaluons, par le biais de simulations, les performances de notre approche contre des algorithmes de décision basés sur des préférences.

Satellite systems have the advantage of global coverage and offer a solution for providing broadband access to end users. Local terrestrial networks and terminals can be connected to the rest of the world over Low Earth Orbit (LEO) satellite networks simply by installing small satellite interfaces. With these properties, satellite systems play a crucial role in the global Internet to support real-time and non-real-time applications. Routing in satellite networks, and the integration of satellite networks and the terrestrial Internet are the key issues to support these services. Furthermore, the developments in space technologies enable the realization of deep-space missions such as Mars exploration. The Interplanetary Internet is envisioned to provide communication services for scientific data delivery and navigation services for the explorer spacecrafts and orbiters of future deep-space missions. The unique characteristics posed by deep-space communications call for different research approaches from those in terrestrial networks. The objective of this research is to develop advanced architectures and efficient routing protocols for satellite and space networks to support applications with different traffic types and heterogeneous quality-of-service (QoS) requirements. Specifically, a new QoS-based routing algorithm (QRA) is proposed as a connection-oriented routing scheme to support real-time multimedia applications in satellite networks. Next, the satellite grouping and routing protocol (SGRP) is presented as a unicast routing protocol in a two-layer satellite IP network architecture. The border gateway protocol - satellite version (BGP-S) is then proposed as a unified routing protocol to accomplish the integration of the terrestrial and satellite IP networks at the network layer. Finally, a new routing framework, called the space backbone routing (SBR), is introduced for routing through different autonomous regions in the Interplanetary Internet. SBR provides a self-contained and scalable solution to support different traffic types through the Interplanetary Internet.
