Повний текст джерелаSession Initiation Protocol (SIP) är ett signaleringsprotokoll för IP-baserade mediatjänster som kommer att bli "de facto"-standard för framtida "media-över-IP"-tjänster. Då SIP User Agents (UAs) stöder ett begränsat antal typer av tjänster (oftast en eller två), antar vi att framtida användare kommer att behöva använda sig av flera UAs samtidigt. Dessa UAs utgör en användares personliga tjänstenätverk. I denna rapport, undersöker vi arkitekturer för policybaserad hantering (management) av detta nätverk, så att det kan användas effektivt. För att uppnå detta, föreslår vi en ny SIP-enhet, kallad SIP Service Manager (SSM), som är placerad i kärnan av hanteringssystemet. Slutligen utvärderar vi vår föreslagna lösning genom att implementera en version av en SIP Service Manager.

Повний текст джерелаUsing both a theoretical discussion and an empirical illustration, this work shows that the INs, especially when they combine public and private service actors, are both a very important theoretical concept and a rising economic reality in service sectors. In the theoretical discussion, we develop a conceptual framework which describes the innovation process in the public-private innovation network in services (ServPPINs). The innovation is produced through the coordination mechanism between the four components of the framework: 1) the inclusion of public and private actors; 2) the dynamic process of interactions between network actors; 3) the existence of social relationships; 4) a network life cycle growth model. This conceptual framework considers the differences in the ServPPINs and their associated innovation output. In the empirical analysis, we employ Lyonbiopole as a case study to describe the innovation process under the conceptual framework of ServPPINs. Also, using French CIS 4 data, we test the effect of cooperation between public and private sectors (ServPPINs) on innovation output

Повний текст джерелаCollaborative-Networks (CN) have experienced a fast evolution in the last two decades. The collaboration among independent entities or professionals supported by Information and Communication Technology (ICT) has attracted the research community to establish the conceptual basis for this scientific discipline. Service Orientation has been one of the key selected paradigms for that conceptual basis. Nevertheless, the service concept itself does not have a common understanding in the Business and ICT worlds. In the former, client satisfaction, resources management and business process models are some example concerns, whilst the later deals with interoperability, remote function calling or communication protocols. If for example an enterprise provides some service, it may hire specialists to wrap such service into web-services, expecting to reach worldwide potential new clients. In fact, nowadays Web Services and Service Oriented Architectures (SOA) are the technological elements most commonly used. However, these are passive elements in the sense they do not perform any action towards pursuing business interests, which constitute a limiting factor from a business perspective. Another approach for the above mentioned enterprise is to follow the Multi-Agent Systems (MAS) approach, as the pro-activity is a keyword in such contexts. Nevertheless, as MAS approaches are not so commonly used and not so robust yet, the worldwide potential set of new clients is reduced; which also constitutes an inhibitor factor from the business perspective. This dissertation proposes a Pro-Active Services Ecosystem Framework, gathering inspiration from both the SOA and MAS research areas, trying to bridge the business and ICT worlds through the base concepts for the creation of a Services’ Ecosystem where business services are represented in a pro-active manner towards pursuing business interests, like finding collaboration opportunities or improving the chances each CN member has to see its services selected among competitors, for example. This work also includes a prototype system applied / validated in the area of a Professional Virtual Community of Senior Professionals.

No obstant, això representa una nova aplicació per Ethernet que comporta nous requeriments. En les xarxes Ethernet, el protocol de Rapid Spanning Tree (RSTP) crea un arbre actiu per evitar cicles i permetre que les xarxes Ethernet funcionin correctament. Hi ha però algunes implicacions de l'ús de RSTP per transformar la topologia física en un arbre actiu: alguns enllaços no utilitzats i la creació de rutes sub-òptimes. A més, RSTP pateix count-to-infinity i tarda massa temps per recuperar-se de caigudes crítiques. En aquesta tesi es proposa una solució completa basada en extensions d’RSTP que aborda les seves deficiències. Dissenyem i avaluem dues extensions: RSTP-Conf per proporcionar una ràpida recuperació i RSTP-SP per operar amb comunicacions per camins òptims.

Повний текст джерелаSensor deployments are becoming more and more common nowadays and the ways to access them are becoming more standardized. Indeed, users want to access sensor data via the Internet and without using some complex and unknown protocol; enter Web Services. By observing the typical system architecture for relaying sensor information to the web, we identified out of a large group of security issues a particular one. The issue in question is user privacy.
In this thesis we focus on hiding the activity of a user who queries a sensor deployment, from an attacker that can listen to communications in the neighborhood of the network. Our goal is to generate extra traffic in an intelligent way so that it can effectively mask user activity without draining the energy from the sensors.

Повний текст джерелаWith the constant development of wireless technologies, the usageof wireless devices tends to increase even more in the future.Wireless multi-hop networks (WMNs) have emerged as a keytechnology to numerous potential scenarios, ranging from disasterrecovery to wireless broadband internet access. The distributedarchitecture of WMNs enables nodes to cooperatively relay othernode's packets. Because of their advantages over other wirelessnetworks, WMNs are undergoing rapid progress and inspiringnumerous applications. However, many technical issues still existin this field. In this thesis we investigate how Voice over IP(VoIP) and peer-to-peer (P2P) application are influenced bywireless multi-hop network characteristics and how to optimizethem in order to provide scalable communication.We first consider the deployment of VoIP service in wirelessmulti-hop networks, by using the Session Initiation Protocol (SIP)architecture. Our investigation shows that the centralized SIParchitecture imposes several challenges when deployed in thedecentralized wireless multi-hop environment. We find that VoIPquality metrics are severely degraded as the traffic and number ofmultiple hops to the gateway increase. In the context ofscalability, we further propose four alternative approaches whichavoid current limitations.In the second part of this thesis we tackle the network capacityproblem while providing scalable VoIP service over wirelessmulti-hop networks. The performance evaluation shows the influenceof intra and inter-flow interference in channel utilization, whichdirect impacts the VoIP capacity. In order to avoid the small VoIPpacket overhead, we propose a new adaptive hop-by-hop packetaggregation scheme based on wireless link characteristics. Ourperformance evaluation shows that the proposed scheme can increasethe VoIP capacity by a two-fold gain.The study of peer-to-peer applicability over wireless multi-hopnetworks is another important contribution. A resource lookupapplication is realized through structured P2P overlay. We showthat due to several reasons, such as characteristics of wirelesslinks, multi-hop forwarding operation, and structured P2Pmanagement traffic aggressiveness the performance of traditionalP2P applications is rather low in wireless multi-hop environments.Therefore, we suggested that a trade-off between the P2P lookupefficiency and the P2P management traffic overhead can be achievedwhile maintaining the overlay network consistency in wirelessmulti-hop networks.

Повний текст джерелаEls Sistemes de Transport Intel·ligents (ITS) han impulsat les comunicacions vehiculars en l'actualitat. Les comunicacions vehiculars és un camp d'investigació de moda, i està atraient un gran interès en la indústria automobilística i de les telecomunicacions. En el camp de les comunicacions vehiculars, hi ha principalment dues línies de treball: (1) serveis de comunicacions relacionats amb la seguretat viària i la informació del trànsit; i (2) serveis d'informació i entreteniment, també anomenats serveis d'infotainment. Aquests últims inclouen tant serveis multimèdia (veu sobre IP, streaming, jocs on-line, etc.), com serveis clàssics de dades (correu electrònic, accés a xarxes privades, navegació web, compartir arxius, etc.). En aquesta tesi ens centrarem en aquests serveis d'infotainment ja que és necessari aprofundir en la investigació per aquests tipus de serveis, ja que, fins avui, els esforços de la comunitat científica en el camp de les comunicacions vehiculars s'ha centrat en els serveis relacionats amb la seguretat viària i la informació del trànsit. Els nodes vehiculars necessiten tenir connexió a Internet per a poder tenir accés als serveis d'infotainment. Mentre els vehicles estan en moviment a través de la xarxa viària, els vehicles han d'anar canviant el punt de connexió sense fils amb la xarxa. Durant aquest procés de canvi de punt de connexió, anomenat handoff, es perd la connectivitat fins que el vehicle es reconnecta a un altre punt de connexió viària prop de la seva àrea. Aquesta desconnexió causa interrupcions en les comunicacions. Uns handoffs ràpids són bàsics a les xarxes vehiculars per a evitar llargs períodes d'interrupció durant les comunicacions, ja que la gran velocitat a la que es mouen els nodes vehiculars significa un gran nombre de handoffs durant una connexió a Internet. Aquesta tesi es centra en serveis d'infotaiment en temps real per a comunicacions Vehicle-a-Infraestructura (V2I). Les principals contribucions d'aquesta tesi son: i) un nou marc de proves per a les comunicacions (V2I) per a poder provar serveis d'infotainment d'una manera fàcil; ii) l'anàlisi de la viabilitat del desplegament de serveis d'infotainment de vídeo en xarxes vehiculars utilitzant protocols de mobilitat IP; i iii) el desenvolupament d'una nova arquitectura TCP que proporciona un millor funcionament per a tots aquells serveis d'infotainment basats en el protocol TCP en un escenari vehicular amb handoffs. En aquesta tesi, primer proposem un nou marc de proves per a aplicacions vehiculars d'infotainment. Aquest marc és una plataforma d'emulació vehicular que permet provar aplicacions reals instal·lades en màquines virtuals Linux. Utilitzant l'emulació, som capaços d'avaluar el rendiment d'aplicacions reals amb característiques de temps real. D'aquesta manera es poden avaluar aplicacions multimèdia utilitzades per oferir serveis d'infotainment d'una forma senzilla en escenaris vehiculars. Segon, utilitzant el marc de prova implementat en la primera part de la tesi, hem avaluat el rendiment d'un servei d'infotainment. Entre aquest tipus de servei, creem que els serveis de vídeo sota demanda en autopistes/autovies serà interessant pels usuaris i generarà beneficis per als operadors de la xarxa. Per tant, hem avaluat com els handoffs a nivell de la capa de xarxa poden limitar el desplegament d'un servei de streaming de vídeo sota demanda. D'acord amb els resultats obtinguts, conduir a grans velocitats podria ser un problema per a poder reproduir un vídeo correctament, tot i utilitzar tècniques de handoffs ràpids. Finalment, hem desenvolupat una nova arquitectura TCP per a millorar el rendiment del protocol durant els handoffs. La majoria dels serveis d'infotainment utilitzen el Protocol de Control de Transport (TCP), un dels principals protocols de la pila de protocols d'Internet. Però existeixen forces problemes relacionats amb l'ús de TCP i la mobilitat que n'afecta el rendiment, i aquests problemes són particulars

Повний текст джерелаENGLISH ABSTRACT: Neural networks are computer systems that attempt to mimic the operation of the human brain. In contrast to traditional systems these systems can learn and will change their behaviour over time. In the highly competitive business environment of today, neural networks is one of many technologies that can assist organisations in gaining a competitive advantage. Neural networks also find application in the financial services industry. Applications range from corporate distress or failure models to forecasting of stock prices and many others. Generally speaking, neural networks often offer an exciting alternative to traditional methods of forecasting and classification in this industry. Neural networks must be implemented with care and judgement, as their performance is sensitive with respect to their construction and architecture. Neural networks, as with other technologies, rarely operate in isolation. Neural networks can be integrated with expert systems, genetic algorithms, data mining and even traditional statistical and operational research techniques. Integration produces systems in which the whole is greater than the sum of the parts. Neural networks are also researched and applied in the South African financial services industry, both at an academic and commercial level. Indications are that South Africa is not far behind the international community in exploring the benefits of neural networks.
AFRIKAANSE OPSOMMING: Neurale netwerke is rekenaarstelsels wat poog om die werking van die menslike brein na te boots. In kontras met tradisionele stelsels, leer neurale netwerke en verander dus hul gedrag met verloop van tyd. In vandag se hoogs kompeterende besigheids omgewing, is neural netwerke een van vele tegnologieë wat organisasies kan gebruik om ‘n mededingende voordeel te bekom. Neurale netwerke het ook toepassing in die finansiële dienste industrie. Toepassings wissel van korporatiewe mislukkings modelle tot die vooruitskatting van aandele pryse en vele ander. Neurale netwerke bied ‘n opwindende alternatief tot tradisionele modelle vir vooruitskatting en klassifikasie. Toepassings van neurale netwerke moet egter met oorleg plaasvind, aangesien hul prestasie sterk afhanklik is van hul konstruksie en argitektuur. Soos met ander tegnologie, word neurale netwerke selde in isolasie geïmplementeer. Neurale netwerke kan met sukses geïntegreer word met ekspert stelsels, genetiese algoritmes, data ontginnings metodes sowel as tradisionele statistiese of operasionele navorsings metodes. Integrasie bied stelsels wat meer bied as die som van die onafhanklike komponente. Neurale netwerke word ook in die Suid-Afrikaanse finansiële industrie nagevors en toegepas. Alle indikasies dui daarop dat, met betrekking tot die navorsing van voordele van neurale netwerke, Suid Afrika nie ver agter die internasionale gemeenskap is nie.

Повний текст джерелаA recente proliferação de nós móveis com múltiplas interfaces sem fios e a constituição de ambientes heterogéneos possibilitaram a criação de cenários complexos onde os operadores de rede necessitam de disponibilizar conectividade para diferentes tipos de redes de acesso. Assim, a norma IEEE 802.21 foi especificada de forma a facilitar e optimizar os procedimentos de handover entre diferentes tecnologias de acesso sem perda de conectividade. Para cumprir o seu propósito, a norma disponibiliza serviços chamados Media Independent Handover e que permitem o controlo e a obtenção de informação de diferentes ligações. A configuração estática destes serviços por parte do nó móvel torna-se ineficiente devido aos múltiplos cenários possíveis. Desta forma, o nó móvel deve descobrir nós da rede que providenciem serviços de mobilidade e as suas capacidade de uma forma dinâmica. Nesta dissertação, um conjunto de mecanismos para descoberta de serviços de handover independentes do acesso são analisados, implementados e avaliados em termos de duração e quantidade de informação trocada. Um novo mecanismo de descoberta de entidades locais é também proposto e avaliado, demonstrando que a sua utilização aumenta o desempenho e requer a troca de menos quantidade de informação.
The recent proliferation of mobile nodes with multiple wireless interfaces, in addition to the creation of heterogeneous environments, created complex scenarios where network operators need to provide connectivity for di erent kinds of access networks. Therefore, the IEEE 802.21 standard has been speci ed to facilitate and optimize handover procedures between di erent access technologies in a seamless way. To ful l its purpose, it provides Media Independent Handover services which allow the control and gathering of information from di erent links. The static con guration of these services by the MN becomes ine cient due to the amount of possible scenarios. Thus, the MN must discover the network-supporting nodes and their capabilities in a dynamic way. In this work, a series of proposed Media Independent Handover discovery procedures are analyzed, implemented and evaluated in terms of duration and amount of exchanged information. In addition, a novel discovery procedure for local entities is proposed and evaluated, showing that its deployment increases the performance and requires less information exchanged.
