Denial-of-Service (DoS) attacks form a very important category of security threats that are possible in MIPv6 (Mobile Internet Protocol version 6). This thesis proposes a scheme for participants (Mobile Node, Home Agent, and Correspondent Node) in MIPv6 to recover from DoS attacks in the event of any of them being subjected to a DoS attack. We propose a threshold based scheme for participants in MIPv6 to detect presence of DoS attacks and to recover from DoS attacks in the event of any of them being subjected to a DoS attack. This is achieved using an infrastructure for MIPv6 that makes such a solution practical even in the absence of IPsec infrastructure. We propose a protocol that uses concepts like Cryptographically Generated Addresses (CGA), short-term IP addresses using a Lamport hash like mechanism and a hierarchy based trust management infrastructure for key distribution. However, reasoning about correctness of such protocols is not trivial. In addition, new solutions to mitigate attacks may need to be deployed in the network on a frequent basis as and when attacks are detected, as it is practically impossible to anticipate all attacks and provide solutions in advance. This makes it necessary to validate solutions in a timely manner before deployment in real network. However, threshold schemes needed in group protocols make analysis complex. Model checking threshold-based group protocols that employ cryptography have been not successful so far. The testing in a real network or a test bed also will not be feasible if faster and frequent deployment of DoS mitigation solutions is needed. Hence, there is a need for an approach that lies between automated/manual verification and an actual implementation. It is evident from existing literature that not many simulations for doing security analysis of MIP/MIPv6 have been done. This research is a step in that direction. We propose a simulation based approach for validation using a tool called FRAMOGR [40] that supports executable specification of group protocols that use cryptography. FRAMOGR allows one to specify attackers and track probability distributions of values or paths. This work deals with simulation of DoS attacks and their mitigation solutions for MIP in FRAMOGR. This makes validation of solutions possible without mandating a complete deployment of the protocol to detect vulnerabilities in a solution. This does away with the need for a formal theoretical verification of a DoS mitigation solution. In the course of this work, some DoS attacks and recovery mechanisms are simulated and validated using FRAMOGR. We obtained encouraging results for the performance of the detection scheme. We believe that infrastructure such as FRAMOGR would be required in future for validating new group based threshold protocols that are needed for making MIPv6 more robust.

During the dot com era the word 'personalisation' was a hot buzzword. With the fall of the dot com companies the topic has lost momentum. As the killer application for UMTS or the mobile internet has yet to be identified, the concept of Multi-Dimensional-Personalisation (MDP) could be a candidate. Using this approach, a recommendation of mobile advertisement or marketing (i.e., recommendations or notifications), online content, as well as offline events, can be offered to the user based on their known interests and current location. Instead of having to request or pull this information, the new service concept would proactively provide the information and services – with the consequence that the right information or service could therefore be offered at the right place, at the right time. The growing availability of "Location-based Services“ for mobile phones is a new target for the use of personalisation. "Location-based Services“ are information, for example, about restaurants, hotels or shopping malls with offers which are in close range/short distance to the user. The lack of acceptance for such services in the past is based on the fact that early implementations required the user to pull the information from the service provider. A more promising approach is to actively push information to the user. This information must be from interest to the user and has to reach the user at the right time and at the right place. This raises new requirements on personalisation which will go far beyond present requirements. It will reach out from personalisation based only on the interest of the user. Besides the interest, the enhanced personalisation has to cover the location and movement patterns, the usage and the past, present and future schedule of the user. This new personalisation paradigm has to protect the user's privacy so that an approach supporting anonymous recommendations through an extended 'Chinese Wall' will be described.

Internet services play an increasingly important role in modern society. Mobile Internet, a fast-growing technology that combines the Internet with mobile devices, has recently become popular. It is predicted that the convergence between mobile networks and the Internet would become the next generation of network architecture, and mobile IPv6 is likely to emerge as the most efficient and cost-effective instrument to achieve "anywhere and anytime" fast Internet and resolve the problems of worldwide mobility management. This research project reviews mobile Internet competition and the market mix in New Zealand, both major players and minor players being involved. The researcher also investigates the requirements of the mobile Internet deployment model from two perspectives: the market and the consumers. Finally the connection between end user services (for example, mobile Internet) and convergence (for example, network convergence and technology convergence) are examined in the research study conducted.The researcher applies a multi-case study strategy to conduct the research project and interview is adopted as the major research technique in order to collect research data. Several organizations which deploy mobile Internet services in New Zealand are chosen as participants, with the aim of offering both personal insights and business views to the research questions and objectives.

Mobile devices are becoming widely common today. As the number of mobile devices continue to grow all around the world, its functionality is extending and mobile technologies are gaining more popularity in every aspect of our life. Today, wide range of mobile services is offered to people. The purpose of our study is examining the customer value of mobile services for individuals or citizens. A value model for mobile services has been proposed with five dimensions: Functional Value, Social Value, Emotional Value, Epistemic Value and Economic Value. The effect on each value dimension on Intention to Use (ITU) is aimed to be determined. A survey instrument for mobile Internet services and short message services (SMS) has been developed to validate the proposed model. After assuring the reliability of instrument with a pilot study, data was collected from 303 people working in information and communication technologies (ICT) sector in Turkey. For analyzing proposed model variance-based structural equation modeling (partial least squares) was used. Before evaluating model, exploratory factor analysis (EFA) was conducted to indentify underlying constructs. Based on EFA results, Functional Value was found to have sub-dimensions namely: Ubiquity Value, Performance Value and Security Value. The measurement model was analyzed using confirmatory factor analysis (CFA). The structural model was analyzed using predictive power. For both mobile Internet and SMS, moderate predictive power has been gathered. Finally, the effect of each value dimension on intention to use (ITU) has been evaluated. Ubiquity Value, Performance Value and Epistemic Value have significant effect on ITU for mobile Internet. On the other hand, Economic Value and Performance Value have significant effect on ITU The indications of this research will be valuable for providing information about customer value of current mobile services.

When internet-mediated messaging and social networking applications were introduced in mobile phones, mobile messaging entered a new paradigm. Users can easily create profiles and communicate with other users instantly at anytime of day and anywhere in the world. This paradigm however, has brought forward new privacy issues. Over the course of this exegesis I aimed to explore different aspects of privacy issues related to mobile messaging, including users' awareness and the control of the privacy issues when using social networking messaging. This was demonstrated by conducting a project, which involved development of a mobile phone application and a role-playing game. The project created a frictional scenario of users communicating via mobile messaging. My research revealed that the participants lacked awareness of privacy violations when using mobile messaging, and tended not to modify their behaviours immediately when privacy breaches arose. This research contributes to the existing body of research in the area of mobile messaging privacy, and advocated user awareness of privacy issues in this domain. It could potentially be used as a base for future research.

Among the main advantages of the marketing usage of m-Commerce belong good focus possibilities, fast response, good measurable records, usability for large or smaller organizations and low expenses on creative solutions. A wide range of solutions is convenient for both, large and small companies. Nevertheless, it seems that its expansion in the Czech Republic is still quite unusual. Key factors of the success of m-Commerce are the fast technical development of mobile phones in many areas, the high penetration of mobile phones in the population ( there were 129,6/100 citizens active sim cards in the Czech Republic in 2008), and its all-purpose utilization. M-Commerce is also a part of the company´s orientation on the multi-channel access to its information system and its particular applications and database.Clients can choose the channel which they consider the most suitable and technically and financially available for their demand.

Mobile Internet is currently considered as the future for the Internet. Apparently the number of mobile handset sold as compared to desktop PCs is noticeable. These hints depict the potential of mobile Internet and the future market strongly relying on mobile devices. But at the same time mobile internet users are growing slower in numbers. Particularly in market where the internet access is very simple through computers, mobile internet users seems not very enthusiastic to use internet on mobile phones. Author of this study supposed on the basis of literature findings that this lack of interest is due to an unsatisfactory mobile internet user experience. This thesis work is an effort into the complex area of mobile internet and shed some light on how to improve user experience for mobile internet. The main focus of this research work is the identification of hurdles/challenges for mobile internet user experience and explores the concepts present in academia. In order to understand it properly, the author performed a systematic literature review (SLR). The overall objective of SLR is to examine the existing work on thesis study topic. This in depth study of literature revealed that mobile internet user experience is categorized into aspects, elements and factors by different researchers and considered as a central part of mobile internet user experience. There are few other factors that affect and make this job complicated and difficult such as usage context and user expectations. In this work current problems of the mobile internet user experience are identified systematically that never happened before and then discussed in a way that provide a better understanding of mobile internet user experience to academia. To fulfill the aim and objectives author of this study conducted the detailed systematic review analysis of the empirical studies from year 1998 to 2012. The research studies were identified from the most authentic databases that are scientifically and technically peer reviewed such as Scopus, Evillage, IEEE Xplore, ACM digital library. From SLR results, we have found different aspects, elements, factors and challenges of mobile internet user experience. The most common challenge faced by user and reported in academia was screen size, input facilities, usability of services, and data traffic costs. The information attained during this thesis study through academia (literature) is presented in a descriptive way which reflects that there is an emerging trend of using internet on mobile devices. Through this study author presented the influencing perspective of mobile internet user experience that needs to be considered for the advancement of mobile internet. The presented work adds contribution in a sense as to the best of knowledge no systematic review effort has been done in this area. / Silvergården 5b lgh 1404 Landskrona Sweden 0735645215

The increase mobile data traffic from the emerging Internet services, especially multimedia, has posed considerable challenges for the telecom industry. Their initial mobile data services business models are generally not compatible with these emerging Internet services. Thus, there is a substantial need to investigate the suitable options to make media as a profitable telecom business sector. However, there are different challenges and opportunity factors in developing sustainable mobile media business in each market, due to the unique circumstances applied as the result of customer characteristics, mobile market situation and regulatory/law enforcement.</p><p>The first purpose of this thesis is to explore the business model options to deliver media services on top of mobile broadband. Although, we limit our focus to Indonesia, we first analyzed the worldwide patterns toward the media services in order to get a broader view of the current trend. We mapped multitudes of actor involved in digital online / on the top (OTT)media service, which together they form different types of constellation in the value network,as well as service, delivery and revenue model. We also put our focus to get the lessons learned from Spotify's business model, by framing it using Chesbrough and Rosenbloom's model.</p><p>The second purpose is to understand the Indonesian mobile user's characteristic toward the mobile media services. We conducted survey to 119 Indonesians, analyzed the result with one sample T-tests and validated it with the correlation tests (Cronbach Alpha and Pearson correlation), within the Unified theory of acceptance and use of technology (UTAUT)framework. Our findings confirm the low willingness to pay, but an open attitude for the services. The mobile device and network quality are not the barriers for them to adopt the services, and there is a tight connection between the decisions to adopt the services with the perception that the service is popular.</p><p>Through those findings, we assessed the feasibility of the identified options and formulated the recommendations. We used our understanding about Indonesian market structure (telecom and media), regulation, and mobile user, as well as the lesson that we got from media services provisioning in Sweden and worldwide trend. We found that the pricing tiers, adjustable pricing, and differentiated features are some of the key success factors.Meanwhile, being part in the point-to-multipoint partnership with the well-known OTT player is the potential position that the Mobile network operators (MNOs) in Indonesia should take in provisioning OTT media services, rather than deliver the services by their own.
