Recently, wireless access to Internet applications and services has attracted a lot of attention. However, there is no single wireless network that can meet all mobile users’ requirements. Con-sequently, integrated heterogeneous wireless networks are introduced to meet diverse wireless Internet applications and services requirements. On the other hand, integrated heterogeneous wireless networks pose new challenges to the design and development of reliable transport mechanisms. Wireless Application Protocol version 2 (WAP 2.0) is one of the promising trans-port mechanisms. It uses wireless profiled TCP (WP-TCP), which is fully compatible with TCP, as one of the reliable transport protocols to cope with the wireless link impairments. For WAP 2.0 to continue providing reliable and efficient transport services in the future, one of the key is-sues is to thoroughly study, understand, and improve its performance in integrated heterogeneous wireless networks. In this thesis, we develop analytical frameworks and propose a solution to respectively study and improve the performance of WP-TCP in integrated heterogeneous wireless networks. Spe-cifically, we consider WP-TCP short- and long-lived flows over integrated wireless local area network (WLAN) and wireless wide area network (WWAN), where WLAN can be static or mo-bile. In order to facilitate the analysis of WP-TCP performance in integrated WLAN and WWAN, we first construct a novel WLAN link model, which captures the impact of both uncor-related and correlated transmission errors, and derive mathematical expressions that describe packet loss probability and packet loss burst length over WWAN-WLAN link. Then, we develop analytical frameworks for studying the performance of WP-TCP short- and long-lived flows. Differently from those reported in the literature, our analytical framework for WP-TCP short-lived flows takes into account both correlated and uncorrelated packet losses. Furthermore, our analytical framework for long-lived flow can be used to study the short-term (during vertical handover) and long-term performances of WP-TCP and it captures the effects of vertical handover, such as excessive packet losses and sudden change in network characteristics, which are commonly experienced in integrated static WLAN and WWAN. By using the devel-oped analytical frameworks, we extensively analyze the performance of WP-TCP flows and in-vestigate the optimal protocol design parameters over a wide range of network conditions. Finally, based on our analytical studies, we propose a receiver-centric loosely coupled cross-layer design along with two proactive schemes, which significantly improve the vertical hand-over performance. The proposed solution is easy to implement and deploy, compatible with tra-ditional TCP, and robust in the absence of cross-layer information. Extensive simulations have been conducted to confirm the effectiveness and practicability of our schemes.

Within the frames of this effort, a detailed recording of technological developments is realised, in terms of technical specifications and standards, in the two aforementioned categories of networks, so as to conclude to those standards that are utilized by the next generation networks (4G) which will be: • Networks that will be unified so as the different technological platforms will function smoothly. • Networks that will be characterized by low cost of deployment. • The end user will be continuously connected with a wireless access network, enjoying the preferred services anywhere and anytime. The master thesis structure follows the aforementioned methodology. The 1st Chapter includes a short presentation of expected results, both in terms of technologies and services for next generation networks, which we usually refer to as 4G networks (4th Generation) or B3G networks (Beyond 3G) or finally as All - IP wireless networks (AIPN). In the 2nd Chapter, a detailed presentation of Mobile Telephony Networks takes place, from their first versions (1G) until the most modern (3.5G) that have been presented up to today. The analysis includes both the various generations of networks and the used standards, in terms of modulation and multiplexing techniques. The rest of the chapter focuses on the technical description of the prevailing networks, GSM, GPRS and UMTS, while the chapter ends with a short description of intersystem handover processes between GSM and UMTS. Τhe 3rd Chapter, includes an extensive description of the Wireless Data Networks standards such as: IEEE 802.15 Wireless Personal Area Networks (WPANs) with main representatives networks based on Bluetooth and IrDA, standard IEEE 802.11 Wireless Local Area Networks (WLANs) mainly represented by WiFi and HyperLan/2, IEEE 802.16 Wireless Metropolitan Area Networks (WMANs) standard, widely known as WiMax and finally the IEEE 802.20 Wireless Wide Area Networks (WWANs) standard, namely Mobile Broadband Wireless Access (MWBA) that is still under development and aspires to constitutes the wireless version of the xDSL technology, since it aims to provide wireless broadband services. In the 4th Chapter methodologies for integrating the two types of networks, are presented along with examples of interoperability between GPRS / UMTS and WLANs or between UMTS and WiMAX. Extensive discussion around the problems that should be faced, as the guarantee of bearable QoS level, the mechanisms for handover between the networks and the management of mobility of users and terminals, is held. Moreover, examples of integrated networks with both loose and tight coupling methodologies are presented. The last section of the chapter concerns a detailed description of architectures for interconnecting heterogeneous wireless networks over IP – based backhaul networks, namely All – IP networks, with special focus on policy based handover mechanisms and techniques for managing micromobility and macromobility issues. The 5th Chapter concerns the changes taking place in the telecommunications market deriving from the technological progress in the subject of heterogeneous wireless networks interconnection. New service packets are created, as a result of new business plans that are drawn up by the big telecommunications organizations. Finally, we present the developments in the Greek market and subsidised projects from Information Society AE, via which wireless networks have been materialised, with aim to promote Broadband Services.

La qualité de communication dans un réseau sans fil est déterminée par la qualité du signal, et plus précisément par le rapport signal à interférence et bruit. Cela pousse chaque récepteur à se connecter à l'émetteur qui lui donne la meilleure qualité du signal. Nous utilisons la géométrie stochastique et la théorie des extrêmes pour obtenir la distribution de la meilleure qualité du signal, ainsi que celles de l'interférence et du maximum des puissances reçues. Nous mettons en évidence comment la singularité de la fonction d'affaiblissement modifie leurs comportements. Nous nous intéressons ensuite au comportement temporel des signaux radios en étudiant le franchissement de seuils par un processus stationnaire $X(t)$. Nous démontrons que l'intervalle de temps que $X(t)$ passe au-dessus d'un seuil $\gamma \to -\infty$ suit une distribution exponentielle, et obtenons également des résultats caractérisant des franchissements par $X(t)$ de plusieurs seuils adjacents. Ces résultats sont ensuite appliqués à la gestion de mobilité dans les réseaux cellulaires. Notre travail se concentre sur la fonction de 'handover measurement'. Nous identifions la meilleure cellule voisine lors d'un handover. Cette fonction joue un rôle central sur l'expérience perçue par l'utilisateur. Mais reste une question ouverte à cause des difficultés posées par la coopération entre plusieurs mécanismes de contrôle qu'elle nécessite. Nous traitons ce problème en proposant des approches analytiques pour les réseaux émergents de types macro et pico cellulaires, ainsi qu'une approche d'auto-optimisation pour les listes de voisinage utilisées dans les réseaux cellulaires actuels.

Data Handover, Dho est une librairie de fonctions adaptée aux systèmes distribués à grande échelle. Dho offre des routines qui permettent d'acquérir des ressources en lecture ou en écriture de façon cohérente et transparente pour l'utilisateur. Nous avons modélisé le cycle de vie de Dho par un automate d'état fini puis, constaté expérimentalement, que notre approche produit un recouvrement entre le calcul de l'application et le contrôle de la donnée. Les expériences ont été menées en mode simulé en utilisant la libraire GRAS de SimGrid puis, en exploitant un environnement réel sur la plate-forme Grid'5000. Par la théorie des files d'attente, la stabilité du modèle a été démontrée dans un contexte centralisé. L'algorithme distribué d'exclusion mutuelle de Naimi et Tréhel a été enrichi pour offrir les fonctionnalités suivantes: (1) Permettre la connexion et la déconnexion des processus (ADEMLE), (2) admettre les locks partagés (AEMLEP) et enfin (3) associer les deux propriétés dans un algorithme récapitulatif (ADEMLEP). Les propriétés de sûreté et de vivacité ont été démontrées théoriquement. Le système peer-to-peer proposé combine nos algorithmes étendus et le modèle originel dho. Les gestionnaires de verrou et de ressource opèrent et interagissent mutuellement dans une architecture à trois niveaux. Suite à l'étude expérimentale du système sous-jacent menée sur Grid'5000, et des résultats obtenus, nous avons démontré la performance et la stabilité du modèle Dho face à une multitude de paramètres.

隨著各種無線網路技術興起至今，各類無線網路技術及產品日益成熟與普及且無線網路的使用者也逐漸變多。而今在各種無線網路的廣泛使用下、時而可見的是當一個行動使用者手持行動裝置身處在一地理環境中，手持行動裝置一經掃描後，常會發現有許多無線網路其覆蓋範圍共同覆蓋在同一個地理區域中，此時多個無線存取點(Access Point)就會發生訊號覆蓋的重疊現象。行動使用者的行動裝置常需判斷是否應該切換到另一個無線網路，此種情形也就是所謂的遞換(Handoff)情形。遞換之產生，代表行動使用者從原本的無線網路區域範圍移動到另一個無線網路範圍，此時若因外界無線電訊號有所變化或是相關網路協定運作出現狀況時、就很容易產生通訊中斷的情形。 在本論文中我們將探討在異質性網路的情況下，根據多種不同的參數、來 設計一個垂直交握(Vertical handoff)的機制。以克服在異質性網路中，時常發生連線中斷之問題。本篇論文主要引使用模糊理論概念來推論其遞換(Handoff)執行的時間點，並且明確的告知終端設備要進入何種網路。 / In this paper, we propose a terminal –control scheme to avoid unnecessary vertical handovers between 3G cellular and WLAN hotspots. The proposed algorithm is a fuzzy logic based algorithm that can adapt itself to the dynamic conditions of the hybrid networks. The scheme can reduce the access delay, unnecessary handoff probability and aid the handoff decision for better connectivity. This handoff algorithm has much better performance than conventional algorithms and can be extended to other heterogeneous networks.

Bakgrund: Runt om i världen och på svenska sjukhus och , överrapporteras dagligen flertaletpostoperativa patienter mellan anestesi-och intensivvårdssjuksköterskor. Vad somkommunicerats har stor betydelse för patienternas fortsatta vård och sjuksköterskornasupplevelse av överrapportering. Bristande överrapportering kan få konsekvenser som sämrevårdkvalité och ökad risk för komplikationer för patienterna. Syfte: Att beskriva anestesi-ochintensivvårdssjuksköterskors upplevelser av överrapportering av postoperativa patienter. Metod:Intervjuer genomfördes i form av fokusgrupper, en med anestesisjuksköterskor och en medintensivvårdssjuksköterskor. Materialet analyserades enligt kvalitativ innehållsanalys. Resultat:Fem huvudkategorier: Behov av att dubbelkolla och dubbeldokumentera, att inte veta vilkeninformation som är relevant och sakna förståelse för varandra, att den postoperativaavdelningen är rörig och orsakar störningar i överrapportering, attoperationssjuksköterskornas överrapportering är viktig och behov av att överrapportera vidpatienterna och upprätthålla fullständig sekretess. Slutsats: Tydliga rutiner behövs gällande vadpostoperativ överrapportering ska innehålla, samt utveckling av samarbete mellan de som deltar iöverrapportering. Behov av att kunna genomföra överrapportering vid patienterna men ändåupprätthålla sekretess var ett komplext område. Operationssjuksköterskans deltagande iöverrapportering var ett av de största förbättringsområden som framkom denna studie.

The telecommunications industry faces difficult challenges as more and more devices communicate over the internet. A telecommunications network is a complex system with many parts and some are candidates for further automation. We have focused on interfrequency measurements that are used during inter-frequency handovers, among other procedures. A handover is the procedure when for instance a phone changes the base station it communicates with and the inter-frequency measurements are rather expensive to perform. More specifically, we have investigated the possibility of using deep learning—an ever expanding field in machine learning—for predicting inter-frequency measurements in a Long Term Evolution (LTE) network. We have focused on the multi-layer perceptron and extended it with (variational) autoencoders or modified it through dropout such that it approximate the predictive distribution of a Gaussian process. The telecommunications network consist of many cells and each cell gather its own data. One of the strengths of deep learning models is that they usually increase their performance as more and more data is used. We have investigated whether we do see an increase in performance if we combine data from multiple cells and the results show that this is not necessarily the case. The performances are comparable between models trained on combined data from multiple cells and models trained on data from individual cells. We can expect the multi-layer perceptron to perform better than a linear regression model. The best performing multi-layer perceptron architectures have been rather shallow, 1-2 hidden layers, and the extensions/modifications we have used/done have not shown any significant improvements to warrant their presence. For the particular LTE network we have worked with we would recommend to use shallow multi-layer perceptron architectures as far as deep learning models are concerned.

The nursing handover report belongs to everyday activities of nurses. In the work of a nurse it is important to know exactly who, when, where, what and how. This is what the following activity and responsibilities of the duty period are derived from. This diploma thesis, focused on the Nursing Handover Report at a Patient´s Bedside, has a theoretical and practical part. The first, theoretical part, is composed of three chapters, the modern trend of nursing, the nursing report and legislation. The second, practical part, is based on quantitative and qualitative surveys with three defined objectives and four hypotheses. The first objective was to determine what nurses regard as a major contribution of the nursing handover report at a patient´s bedside. The second objective was to define the greatest obstacle in the nursing handover report at a patient´s bedside. The third objective was assessing the patients´ attitude towards the nursing handover report at their bedside. All three objectives were met by the research. The qualitative part of this diploma work was based on a conducted kvasiexperiment and subsequent questions for patients and nurses. The research sample was 5 nurses and 5 patients from the intermediate care unit (IMCU) and 5 nurses and 5 patients from the resuscitation station (RES) of the České Budějovice hospital, PLC. The semi-structured interview consisted of six to eight questions, surveying the feelings, contents, visualization, integration, advantages, disadvantages, departments, nursing handover at the bedside and the quality. The data collection was carried out by means of an anonymous questionnaire designed for nurses to find out how nurses hand the report over or how they would like to hand it over. 303 nurses from the České Budějovice Hospital, PLC, and the Příbram Hospital, PLC, took part in the research. The results were used to confirm or to reject the hypotheses. The first hypothesis: Nurses do not consider an oral handover report as a quality one when done without a visual completion, this has not been confirmed by the investigation. The second hypothesis: In terms of the risk of the patient's damage, the quality of the handover report done by the nurses in the IMCU and the RES is better than that done by the nurses in a standard unit, this has been confirmed. The third hypothesis: Nurses consider the time consuming nature of the handover report at the patient´s bedside as the greatest difficulty, this has not been confirmed. The fourth and last hypothesis: Patients have a positive attitude towards the nursing handover report at the bedside, this has been confirmed by the research. The output of this thesis is to suggest a standard for the nursing handover report at a patient´s bedside. The results can be used for nursing managers, deputy directors of nursing, medical students and nursing professionals.

Bakgrund: Överrapportering vid skiftbyte är en essentiell del av sjuksköterskans kliniska arbete, trots detta råder inte konsensus om vilken rapporteringsmetod som är bästa praxis. I takt med en större personcentrering av vården står patientens rätt till delaktighet och medbestämmande i större fokus, och bedsiderapportering har vuxit fram som ett alternativ till den traditionella rapporten. Syfte: Att belysa hur sjuksköterskor och vuxna patienter i den somatiska slutenvården beskriver sin upplevelse av bedsiderapportering. Metod: Denna litteraturöversikt genomfördes som en förenklad metasyntes där dataanalysen baserades på kvalitativ innehållsanalytisk teknik. Resultat: Tre huvudteman framkom gällande patienters upplevelse av bedsiderapportering: patientmedverkan, bättre vårdupplevelse samt möjliga hinder. Ytterligare tre huvudteman framkom för sjuksköterskors upplevelser: upplevda fördelar, möjliga hinder och förutsättningar för bedsiderapportering. Både patienter och sjuksköterskor beskrev positiva upplevelser av bedsiderapportering med den främsta fördelen att patienten blev mer delaktig i vården. Patienter beskrev en ökad trygghetskänsla och ett tillgodosett informationsbehov. Sjuksköterskor beskrev hur patientsäkerheten förbättrades och prioriteringar underlättades av bedsiderapportering. Oro kring sekretess och känslig information lyftes av både sjuksköterskor och patienter. Slutsats: Bedsiderapportering kan utgöra ett värdefullt verktyg i en mer personcentrerad vård, men att ytterligare kunskap behövs kring hantering av sekretessen. / Background: Shift reporting is an essential part of the nurse’s clinical work, despite this there is no consensus about what constitutes best practice. As personcentredness is becoming more important, more focus is on the patients’ right to participation and shared decision-making, and bedside reporting has become an alternative to the traditional shift report. Aim: To illustrate how nurses and adult inpatients within the somatic care describe their experience of bedside handover. Method: This literature review was conducted through a simplified meta-synthesis approach based on qualitative content analysis as a tool for the analysis of data. Results: Three main themes regarding patients’ experiences of bedside handover emerged: patient participation, improved care experience and possible barriers. Three additional main themes regarding nurses’ experiences emerged: perceived advantages, possible barriers and enabling factors for bedside handover. Both patients and nurses reported positive experiences of bedside handover, with the foremost advantage being the patients’ involvement in their care. Patients described an increased feeling of safety and that their needs of information were met. Nurses described how patient safety was improved and how prioritization was facilitated. Both nurses and patients had concerns about confidentiality and sensitive information. Conclusion: Bedside handover can be used as a valuable tool in the work towards a more person centred care, but there is a need for further knowledge about how confidentiality can be managed.
