Full textUtöver de problem som kan uppstå på Internet, konfronteras testare av mobila tjänster av ytterligare utmaningar på grund av den trådlösa miljön. Går något fel kan det vara väldigt svårt att lokalisera var problemet har uppstått och anledningen till varför det uppkom. Är det mjukvaran i telefonen som inte fungerar, är GPRS anslutningen stabil, fungerar kommunikationen över Internet som det ska, eller är det något fel med applikationsservern? De anställda på Sony Ericsson har många gånger stora problem att definiera vad källan till ett problem är. Ofta vet de bara att något är fel. Den stora mödan är ofta att hitta källan till problemet snarare än att lösa det. Tjänsten PlayNow som tillhandahålls av Sony Ericsson är referenstjänst för detta arbete. För närvarande används PlayNow för distribuering av ringsignaler. Tjänsten bygger på Internetstandards, men är även beroende av GSM specifika delar för både distribution och e-handel, vilket gör det svårt att testa denna tjänst med vanliga testverktyg för webben. I detta examensarbete undersöks svårigheterna med att etablera robust IP trafik mellan en mobiltelefon och en server och fokuserar på hur potentiella fel kan upptäckas. Inom ramen för detta arbete har ett testverktyg utvecklats. Detta verktyg tillhandahåller funktionalitet för att testa referenstjänsten PlayNow. Denna rapport behandlar många olika teknologier inom mobilt Internet, såsom GSM, GPRS och Mobil IP. Utöver detta har den vanliga Internet teknologin behandlas. Så som de andra delarna som är inkluderade i mobilt Internet med GPRS. En större del av arbetet har varit utvärdering av kommunikationsvägen mellan klient och server. Utöver detta har en del ansträngning lagts på att utveckla det nya testverktyget. Denna rapport visar på de svårigheter i att hitta källan till ett problem i kommunikationsvägen, vilka kan vara mycket svåra att hitta. För att göra felsökning enklare har ett testverktyg utvecklats. Med hjälp av detta nyutvecklade testverktyg, många brister i konfigurationen av PlayNow servern har blivit upptäckta och tillrättade.

Full textMobility is becoming an integrating part of todays Internet of Things, as many applications such as wildlife monitoring or target tracking in the battlefield cannot be done only with the help of static nodes. The goal of this thesis is to provide new communication architecture articulated around providing mobility support in Low Power and Lossy Networks (LLNs). First we analyzed from a theoretical point of view the IPv6 address auto-configuration with all optimizations made in Neighbor Discovery Optimization for IPv6 over 6LoWPAN. This step is of crucial importance for protocols that offer mobility support in IP networks, such as MIPv6. Our findings, increased message size that leads to fragmentation and high energy consumption for routers that are involved in Neighbor Discovery message exchange, have lead us to use the IPv6 Routing Protocol for Low Power and Lossy Networks (RPL) in order to provide mobility support. RPL is build from ground up with respect to LLN requirements. Our second contribution enhanced RPL operations to support mobility management. Finally, we proposed a cross-layer protocol – Mobility Triggered-RPL – that leverages actions from the X-Machiavel preamble sampling MAC protocol into RPL

Full textCan the socio-economic logic of the club can be apply somewhere else than in the cablo-distribution in Quebec? Answering this question can make use better understand convergence markets of mobile internet investigating users and industrial clubs. Our main hypothesis are the lack of club (for the antiope system), user club as a toy to limitate users autonomy by prescribing uses, industrials club as organizer of the sector according the size and , specialization. Users clubs are made of two functions: "fidelisation" and "to make user to pay". For the industrial clubs, the functions are federation, coalition and normalisation. Elements confirm the importance of the Club socio-economical logic and present four fundamental aspects: the supply logic (a leadership in a membership), the subscription, the traceability and a limitation of the costs

Full textI denna rapport specificeras karaktäristiken för TCP and UMTS, och problemet med TCP över dedikerade UMTS kanaler analyseras. Problemet är höga fördröjningar som medför låg utnyttjande grad av allokerade resurser vid överföring av små filer eller vid paket förluster. High Speed Downlink Packet Access (HSDPA)’s potential att lösa problemet studeras. En modell av HS-DSCH konstrueras och simuleringar utförs för att jämföra dess TCP prestanda med DCH. Fokus är på att studera återsändningsfördröjning och BLER riktvärden. Några scheduleringsmetoder jämförs också. Resultatet indikerar att HS-DSCH ger bättre TCP prestanda än DCH, och att avancerad scheduleringsmetoder ger liknande resultat som round robin vid paket förluster. Dessutom har ett ganska överraskande resultat funnits kring snabb återsändning och kanal utnyttjande grad då BLER riktvärdet ökar.

Full textA evolução constante em novas tecnologias que providenciam suporte à forma como os nossos dispositivos se ligam, bem como a forma como utilizamos diferentes capacidades e serviços on-line, criou um conjunto sem precedentes de novos desafios que motivam o desenvolvimento de uma recente área de investigação, denominada de Internet Futura. Nesta nova área de investigação, novos aspectos arquiteturais estão ser desenvolvidos, os quais, através da re-estruturação de componentes nucleares subjacentesa que compõem a Internet, progride-a de uma forma capaz de não são fazer face a estes novos desafios, mas também de a preparar para os desafios de amanhã. Aspectos chave pertencendo a este conjunto de desafios são os ambientes de rede heterogéneos compostos por diferentes tipos de redes de acesso, a cada vez maior mudança do tráfego peer-to-peer (P2P) como o tipo de tráfego mais utilizado na Internet, a orquestração de cenários da Internet das Coisas (IoT) que exploram mecanismos de interação Maquinaa-Maquina (M2M), e a utilização de mechanismos centrados na informação (ICN). Esta tese apresenta uma nova arquitetura capaz de simultaneamente fazer face a estes desafios, evoluindo os procedimentos de conectividade e entidades envolvidas, através da adição de uma camada de middleware, que age como um mecanismo de gestão de controlo avançado. Este mecanismo de gestão de controlo aproxima as entidades de alto nível (tais como serviços, aplicações, entidades de gestão de mobilidade, operações de encaminhamento, etc.) com as componentes das camadas de baixo nível (por exemplo, camadas de ligação, sensores e atuadores), permitindo uma otimização conjunta dos procedimentos de ligação subjacentes. Os resultados obtidos não só sublinham a flexibilidade dos mecanismos que compoem a arquitetura, mas também a sua capacidade de providenciar aumentos de performance quando comparados com outras soluÇÕes de funcionamento especÍfico, enquanto permite um maior leque de cenáios e aplicações.
The constant evolution in new technologies that support the way our devices are able to connect, as well the way we use available on-line services and capabilities, has created a set of unprecedented new challenges that motivated the development of a recent research trend known as the Future Internet. In this research trend, new architectural aspects are being developed which, through the restructure of underlying core aspects composing the Internet, reshapes it in a way capable of not only facing these new challenges, but also preparing it to tackle tomorrow’s new set of complex issues. Key aspects belonging to this set of challenges are heterogeneous networking environments composed by di↵erent kinds of wireless access networks, the evergrowing change from peer-to-peer (P2P) to video as the most used kind of traffic in the Internet, the orchestration of Internet of Things (IoT) scenarios exploiting Machine-to-Machine (M2M) interactions, and the usage of Information-Centric Networking (ICN). This thesis presents a novel framework able to simultaneous tackle these challenges, empowering connectivity procedures and entities with a middleware acting as an advanced control management mechanism. This control management mechanism brings together both high-level entities (such as application services, mobility management entities, routing operations, etc.) with the lower layer components (e.g., link layers, sensor devices, actuators), allowing for a joint optimization of the underlying connectivity and operational procedures. Results highlight not only the flexibility of the mechanisms composing the framework, but also their ability in providing performance increases when compared with other specific purpose solutions, while allowing a wider range of scenarios and deployment possibilities.

Full textInternet Telephony defined as real time voice or multimediacommunications over packet switched networks dates back to theearly days of the Internet. ARPA's Network SecureCommunications project had implemented, as early as December1973, an infrastructure for local and transnet real time voicecommunication. Two main sets of standards have emerged: H. 323from the ITU-T and the session initiation protocol (SIP) fromthe Internet Engineering Task Force (IETF). Both includespecifications for value added services. Value added services,or more simply services, are critical to service providers'survival and success. Unfortunately, the service architecturesthat come with the ITU-T and the IETF sets of standards arerather weak. Although they are constantly evolving,alternatives and complements need to be researched. This thesiswhich is made up of a formal dissertation and 6 appendices,proposes a novel mobile agent based service architecture forInternet Telephony. The architecture addresses the issues noneof the existing architectures solves in a satisfactory manner.Furthermore it adds mobile agents to the panoply of servicecreation tools. The appendices are reprints of articlespublished in refereed magazines/journals or under considerationfor publication. The formal dissertation is a summary of thepublications. A consistent and comprehensive set ofrequirements are derived. They are TINA-C flavored, but adaptedto Internet Telephony. They are used to critically reviewrelated work and also used to motivate the use of mobile agentsas the pillars of a novel architecture. The components of thisnovel architecture are identified. The key component is themobile service agent. It acts as a folder and carriesservice(s) to which the end-user has subscribed. Mobile serviceagents need to be upgraded when new versions of service logicare available and when end-users make changes to service data.This thesis proposes a novel upgrading framework. The currentInternet infrastructure comprises a wide range of hosts. Mobileagent platforms are now available for most of thesehosts/clients including memory/processing power constrainedPDAs. Our mobile service agents need to adapt to hostvariability when roaming. A novel adaptivity framework is alsoproposed. These two frameworks are general and can be appliedto any other mobile agent which meets a basic set ofassumptions. A key advantage of a mobile agent based servicearchitecture is that it enables the developement of mobileagent based services. The thesis proposes a novel mobile agentbased multi-party session scheduler. The feasibility and theadvantages of the architecture proposed by this thesis havebeen demonstrated by a prototype on which measurements havebeen made. Future work includes the addition of a securityframework to the architecture, and refinenements to theupgrading and adaptivity frameworks. More mobile agent basedservices, especially mobile multi agent based services willalso be developed.

Over the past five years, mobile Internet services in Japan have seen major expansion as a result of collaboration between mobile operators acting as mobile portal providers, and their complementors, namely, content providers. However, the content business is currently under pressure to become profitable, and major players have found it difficult to differentiate their services from competitors In other words, service has become commoditized, which has resulted in a shift to the mature stage. This thesis suggests Web services as a solution to overcoming the commoditization of mobile Internet services and spurring new development in the industry. This emerging technology allows users to create a combination of Web resources through two fundamental approaches that lead to an innovation. The Web service requester approach enables integration of a variety of Web services as complementary assets from their business partners into their content. System Dynamics modeling methodology is used to examine how Web service requesters could promote product and process innovation as well as outsourcing. The analyses indicate that it is critical to adopt a different strategy under different scenarios of Web services diffusion, taking into consideration the requesters' dependence on Web service providers. The Web service provider approach offers an excellent opportunity to create distribution channels for services. Two case studies are analyzed in depth to understand how the subject companies took advantage of being a Web service provider with the support of complementors as well as users to promote innovation. Finally, suggestions are made for how the mobile industry value chain could evolve through Web services implementations, and policy
(cont.) recommendations are offered for major stakeholders. Web services will likely enable close collaboration between players in the industry, including Web service providers, Web service requesters, and toolkit developers, all of which should see increasing value, which leads to further evolution of the mobile Internet industry.

Full textTekniken kring mobiltelefoni är under ständig utveckling och mobiltelefonen har idag fått nya funktioner utöver dess grundfunktion röstsamtal. Efterfrågan efter nya mobila tjänster drivs hela tiden framåt då mobilen får allt större kapacitet och prestanda. Bland de tjänster som växts fram märks möjligheten att utföra monetära transaktioner. Detta innebär helt enkelt att använda sin mobiltelefon för att betala och utföra allehanda tjänster kopplade till användarens monetära tillgångar. Överföringen av pengar kräver dock hög säkerhet. Vad vet egentligen konsumenterna om säkerheten kring dessa tjänster? Många betalningar och transaktioner sker idag över Internet och bankerna förmedlar budskapet om att säkerheten runt deras Internettjänster är mycket hög, men vad säger de om säkerheten för deras mobila alternativ? Finns den höga säkerheten även för de mobila tjänsterna och har användarna förtroende fullt ut för dessa? Finns inte användarnas förtroende för säkerheten hos de nya mobila tjänsterna kommer de troligtvis inte heller användas. Vi ämnar därför i denna uppsats utreda om säkerheten i en mobil betalningstjänst motsvarar den som finns när den utförs på en dator i hemmet och har detta i slutändan användarnas förtroende?
Syftet med detta arbete är att undersöka vilket förtroende användarna har för säkerheten hos mobila betalningstjänster samt om dessa tjänster uppfyller samma säkerhetskrav som när de används via normal datoranvändning. Studien påbörjades med en genomgång av befintlig litteratur inom säkerheten för mobilt Internet samt Internetanvändande vid hemdatorn. Sedan genomfördes intervjuer av personer med stor kunskap kring säkerheten hos mobilt Internet. För att få reda på användarnas förtroende kring mobila betaltjänster genomförde vi sedan en webbaserad surveyundersökning varvid en fokusgrupps-undersökning användes till hjälp gällande framtagningen av frågorna. Utfallen från intervjuerna samt surveyundersökningen analyserades sedan tillsammans med utvald teori.
Våra resultat visar att majoriteten av respondenterna inte känner förtroende för säkerheten hos mobila betalningstjänster. De flesta anser att det inte är lika säkert att surfa via mobilen som via datorn i hemmet. Däremot kan hälften av individerna i populationen tänka sig att betala över Internet med mobiltelefonen och en betydande del kan även tänka sig att utföra finansiella affärer med hjälp av mobiltelefonen. Vi anser också att en mobiltelefon inte når upp till samma säkerhetsnivå som hos en stationär dator med fast Internet.
The mobile technology is under constant development and the mobile phone today has many other functions besides just talking. The demand for new mobile services is constantly getting stronger since the mobile phone becomes more and more powerful. Among these services is the possibility to perform transactions of money. With this we mean using the mobile phone to pay bills and other services that is connected to a user’s assets. The transaction of money of course requires high security. What do the consumers know about the security surrounding these kinds of services? Today many payments and transactions that involve money takes place over the Internet from the home computer and the banks that offers these services claims that this is safe. But what do they say about the security surrounding their mobile alternatives? Does the necessary security exist for these mobile services and does it have the consumers trust? If the users do not trust the security surrounding the mobile service, they will probably not use them. We will therefore with this thesis try to investigate if the security that surrounds the mobile payment services is equivalent to when the services is used on a home computer and if the services has the users trust?
The purpose with this thesis is to investigate the users trust regarding mobile payment services and if these services fulfil the same security demands as when they are used normally at the home computer. The study began with a review of existing theories regarding the security for mobile Internet and Internet usage on the home computer. Thereafter interviews took place with experts having great knowledge regarding mobile Internet security. We then performed a web-based survey to get information about the users trust for the security surrounding mobile payment services. We used a focus group with the aim of helping us selecting relevant questions for the survey. The results from the interviews and the survey study were then analyzed with the chosen theory.
On the basis of our survey we can draw the conclusion that the majority of respondents do not trust the security that surrounds mobile payment services. The majority is of the opinion that it is not as safe to use mobile Internet services as to use the corresponding service from the computer at home. However half of the population could very well consider paying bills with the mobile phone and a large part of the respondents would also like to use financial transactions with this kind of media. We also conclude that a mobile phone does not reach the security standard of a home computer.

The Internet Protocol (IP), established by IETF, is a standard for internet communication, which supports the network node addressing and packet routing, and currently has two versions: IPv4 and IPv6. The routing method compares the network prefix coded of the packets to determine the routing path. When roaming to the other network, the un-updated prefix code will cause the packets sending to wrong destination. Followed by the progress of wireless network technology, various mobile devices roaming around different networks make the problem of packet loss more crucial. Solutions for these problems were proposed, such as “Mobile IP” and “Mobile IPv6” by IETF, most of them need to remodel the current network architecture or to revise the packet format to achieve IP’s mobility. So it’s too complicated to be accepted by public. This pager proposes a new method for IP mobility, which adopts a mutual endorsement scheme on both networks. It also gets connection for authentication and information exchange by TCP and inquires the latest address by ICMP. In addition, the IP mobility can be achieved without changing network architecture or packet format. Through implementation, we have proved the validation of this method.

Internet and mobile communication are two of the most important trends in recent years. Although people have also talked about mobile Internet for a few years, there was not really a mobile Internet, except NTT DoCoMO’s i-mode demonstrated some kind of success. But as technologies and business models keep evolving; those prerequisites for integrated user experience and a true mobile Internet are getting mature. Under this new circumstance, the mobile Internet will have an open ecosystem for third party applications and devices. There are many value chains of different industries involved in the open ecosystem of mobile Internet 2.0. In this thesis, these industries related to mobile Internet and those business wars happened between players on these value chains are first described. Then the evolution of mobile Internet from a closed ecosystem to an open one will be introduced. This research proposes a value network, derived from related value chains jointly, to provide an overview of the open ecosystem of mobile Internet 2.0, for better understanding the multiple relationships of cooperation and competition between these players. Based on the knowledge of the value network of mobile Internet, the initiatives and their strategic implications of some important players or companies will be analyzed for further comprehension of the current and future development of the Mobile Internet 2.0. The cases analyzed in this research include mobile operators, Google, Yahoo, Microsoft, Nokia and Apple. In addition some advices are also provided to smaller players or new participants.

This research is mainly discussing how the developed mobile network and the popularity of smartphone influence the traditional conversation way. By the limit of wired network, in the past, the internet phone was greatly limited the way people used. Now, because of the mature of 3G network, not only the stability of a substantial increase in mobile networks, but also the price of internet phone is lower than the traditional phone. Those reasons increase the willingness of consumers to use. Based on Rogers’ diffusion of innovation theory, this study explores the impact of the compatibility, relative advantage, usability, functionality, and service, to observe consumers’ willingness of using the mobile network to make an internet phone call. The results showed that age is significant in impact of usability, in the range of 21-30 years old, the respondents are more concerned about this impact. Gender is significant in both of functionality and service impact. In the functionality impact, men are more consider than women. But, in the service impact, women are more consider than men.

The security of home, office, laboratory, warehouse and factory is important to human being. An accident was often caused by the negligence of humans. The burglary, fire accident and toxic gas accident are increasing, year by year. Recently, the internet based robotic systems have been successfully applied in factory automation, dangerous environments, hospitals, surgery, entertainment, space exploration, farmland, military, service, etc. Users can easily know what happens and control the situation through remote supervisory control interface of a robot system. The two major topic of this thesis are to develop a kernel for subsystems cooperation in the robotic and a technique suitable for internet based supervisory control systems. The robot system is basically a decentralized architecture through a kernel controller to handle the activity of each subsystem. Each subsystem has the capability to deal with a specific assignment by its intelligence. The cooperation of the overall subsystems is through the communication handled by a kernel. Finally, the operator could control a mobile robot and monitor environment situation by connecting a kernel through the internet or LAN. It is more convenient and efficient for operators to control an intelligent robot by selecting supervisory control mode or direct control mode on the interface with GUI or human-language-like commands.

Internet is a kind of new communication model in the end of the 20th century. However, with the rapid growth of telecommunication technologies, comes a brand new communication paradigm: mobile Internet. According to the research presented by Ovum in 2003, the total revenue of mobile Internet market may reach 71 billion dollars high in 2007. Although the usage of mobile Internet has been expected to increase rapidly, the profits of mobile Internet services providers do not seem to meet their expectations. As a result, this may result from mobile Internet users’ initial adoption behavior. The main objective of this study is to investigate the critical factors that affect users’ and nonusers’ adoption of mobile Internet. After literature review, the study proposed an adoption model for mobile Internet adoption which consists of seven critical factors: perceived of usefulness, perceived ease of use (usability), system quality, social influence, compatibility, playfulness, and perceived sacrifice. An on-line survey was conducted in order to find more mobile Internet users. The result of this study is to understand the difference between the two groups under the impact of seven critical factors. There are 409 valid samples returned, including 151 users and 258 nonusers. The interviewees can be divided into three categories: users, potential users, and nonusers. In demographic variables, education and personal income have significant difference among the three. There is also difference among the three in the seven critical factors except system quality. In regression analysis, this study found that ‘perceived usefulness’, ‘compatibility’, ‘playfulness’, have great influences on users’ and potential users’ attitude toward mobile Internet service. To have more effective ways of marketing and customer retention, in the future providers have to make great efforts to enrich their contents with usefulness and playfulness, and to improve interface.

In the diversification of teaching environment, learning places are no longer limited to classrooms. The learning contents can also be presented in various ways. In such a learning environment, software of computer-assisted instruction with distinguishing features of multimedia that can promote user’s learning motivation and effect. In this paper, we present three kinds of teaching software that uses animation to help users to understand teaching contents. In our implementation, the users can learn teaching contents by using different terminal devices in anywhere and at anytime. Especially, the teaching software of Wireless Application Protocol (WAP) version presents a new concept of learning. Most WAP websites provide text-only content. Animation is one of the desirable features for WAP servers. However, most WAP toolkits do not provide animation tools for WAP websites. In order to improve the common limitation of the WAP toolkits, we also present WAP animation templates and a templates processor that can generate animation WML codes automatically.

This paper uses TAM and TRA to explore consumer attitude to mobile internet completely, and combines subjective norm influencing on attitude. We also integrate variables influencing on attitude from mobile internet literatures. Besides, we use expe-rience of mobile internet to compare the difference. In this paper, samples are both mobile phone subscribers and internet users. The collected data were analyzed and con-firmed hypotheses by using SEM. The results indicate that attitude positively influence intention and found consum-ers are significantly influenced by perceived ease of use、perceived usefulness、perceived enjoyment and perceived price. This paper also indicates image、perceived enjoyment、perceived quality and subjective norm have significantly difference between experience and inexperience samples. In addition, we also understand telecommunication operators can promote mobile internet for different groups.

The target of this study is to develop a smart antenna array for mobile communication application, so as to improve the transmission efficiency and interference suppression. The center frequency of 2.4 GHz is chosen, which is one of the ISM band (Industrial Scientific Medical Band) and is commonly used for WLAN (IEEE 802.11b / IEEE 802.11g), Bluetooth, and ZigBee applications. Most of the conventional antenna designs for mobile application are omnidirectional ones because the signal may come from any direction. However, this does not lead to optimal data transmission performance and the antenna will also receive interferences from all directions. Since the wanted signal comes from a particular direction only, we propose an antenna array for mobile devices, in which the relative phases of the antenna elements are varied in a way that the main beam of the radiation pattern can be set to the desired direction with suppression of undesired interferences from other directions. This work employs a 2×2 patch antenna planar array on a PCB (printed circuit board) size of 200 mm ×137.5 mm, which is about the size of a 7.9 inch tablet. The relative phase of the antenna feed is controlled by digital phase shifters. The main beam of proposed antenna array can be set to four directions, which are the east, west, south, and north sides. The measured bandwidth for 10 dB return loss is about 4.6%, with a peak gain of 1 dBi and a HPBW (half-power beam width) of about 50 degree. It can be applied to the back of tablet of size larger than 7.9 inch for improving the transmission efficiency and interference suppression.

At present, information and technology are very advanced, people almost received information about what happened outside all the time. In the past, people through television, newspapers and radio to received information, but now, because of technology of internet is more and more advanced they can through computer or mobile to received anything they want know. Although the mobile internet is very advanced, but there are still have not many people to use it in Taiwan. This study is want to know what factors can attract people to use mobile internet. This study proposes a research framework that integrates enjoyment and switch cost with technology acceptance model (TAM), theory of planned behavior (TPB). We used the proposed model to explore antecedents of consumers’ behavioral intention to adopt mobile internet. We used structural equation modeling (SEM) to examine relationships among constructs in the proposed model. Our findings indicated that perceived ease of use, perceived useful and perceived enjoyment are significantly influence on attitude toward and behavioral intention, and perceived behavioral control is not significantly influence behavioral intention. The group of high switch costs is less effect than group of low switch cost on behavioral intention, and subjective norm is more heavily effect group of high switch cost than group of low switch cost. Keywords: switch cost, TAM, TPB, mobile internet
