  • Mobile IP is a solution for mobility on the global Internet. However, it causes service delay incase of frequent movement of mobile node and mobile users. Mobile IP regional registration is Proposed to reduce the service delay. In this paper, we introduce an optimal regional location management mechanism for Mobile IP that reduces the registration delay. The movement of mobile node is described by a discrete analytical model. The proposed model explains analytically average packet rate and registration cost as the size of regional networks with mobility of mobile node.

  • The era came that by having fastest internet and smart phone makes cloud computing really a big merit. This paper proposes architecture for medical image volume rendering in mobile environment using cloud computing. This architecture to replace expensive workstation server and storage it use one of the service of cloud computing IaaS(Infrastructure as a Service). And this paper propose to use webGL to get rid of restriction of mobile hardware. By this research, it is expected that medical image volume rendering service in mobile environment is more effective and can be a foundation work.

  • The purpose of this paper is to estimate 'willingness to pay' for mobile data service by using contingent valuation method with double bounded dichotomous choice question. The findings are as follows.: First, the willingness to pay of mobile data service is considerably lower than current retail price. Second, the perceived degree of mobile data service such as awareness and benefit recognition is positively related to the willingness to pay of mobile data service. Our results suggest that active promotion and strengthening of the content of mobile data service are needed in order to enhance the profitability of mobile operators. The analysis results will be used to set the mobile operator's pricing strategy and to build up a successful communication policies in the mobile ecosystem.

  • Mobile IPv6 services exposes its vulnerability when a mobile node is roaming across the subnets which belongs to the different domains. The AAA Infrastructure Is strongly recommended when the ISPs need to authenticate the mobile user come from the different domains. In addition to the basic requirements for AAA service, the authentication latency and AAA message overhead should be minimized for contiguity of the service. This paper considers the roaming service with AAA infra structure in Mobile IPv6 and proposes the key distribution method to authenticate the mobile node with secure manner by reducing and optimizing the exchanged messages for AAA entities.

  • Nowadays, it is not unusual to buy and sell goods, service and information through the internet. As a result of rapid development of Information Technology(IT), business through the internet can be done without time Limitations, place restrictions and product limitations. However, internet shopping has been restricted a lot due to the need for physical connections to the internet in order to search for information and order what we want, and this is one of the biggest problems to the busy people of the 21st century. Therefore it is very natural to use mobile phones to do shopping through wireless internet easily and conveniently whilst on the move. The purpose of this research is to find out characteristics of mobile phone users in UK, Japan and Korea and 1) main aims of the mobile phone use, 2) reasons for ease of use of mobile phones, 3) favourite types of a mobile phone, 4) psychological stability of mobile phone users, 5) problems of mobile phone use, 6) purchase goods/services via mobile phone in the future. The research method used is questionnaire survey The research results will suggest how to take actions to promote mobile commerce in the future.

  • Recently, with the proliferation of smart phones and mobile devices and the increase in the speed of mobile Internet, IT services are increasingly used in smart phones and mobile devices in a different way from the past. That is, a cloud service that downloads and uses data stored in the server in real time is expanding, and as a result, the security due to the continuous Internet connection of the user becomes a problem. In this study, we analyzed the relationship between factors affecting the continuous use of personal cloud service by using technology acceptance model. In addition to the technology acceptance model, confidentiality, privacy, accessibility, innovation, and self-efficacy were extracted from the existing research with emphasis on the characteristics of the cloud service and security factors. Moreover, the difference of intention to use among genders was verified through structural equation modeling with survey data from 262 personal cloud service users.

  • Although the volume of mobile internet services has increased continually over the years, the rapid diffusion has still fallen short of expected quality. This paper considers mobile internet service industry in Korea as a system failure due to structural problems and attempts to identify systemic imperfection mechanisms from the supply side. The problems of mobile internet industry in Korea are categorized into interaction failures, institutional failures and capabilities failures which contribute to system failure and at the same time, failure types are linked to each other. It is needed to improve policy and institutions in operation and develop new policy for contents providers to promote mobile internet industry. This research findings will contribute to policy making to promote mobile internet service industry and development of sectoral system for emerging industries.

  • The mobile environment which is based on the Internet is expanding the area of the web information systems. The mobile Internet is expanding mobile content and services due to the development of wireless network technology, the proliferation of smart terminal devices, and the emergence of a variety of mobile services platforms. A mobile web is to access to the Internet service using a mobile network or other wireless network using a smart phone or a mobile device. Recently, it is to increase the smart phone usage rapidly in the country, and many companies is entering the mobile market. There are increasing need for this operation plan of a mobile web information system. In this paper, we compared the COBIT, ITIL, the SLA, which are the International Information Systems operation standards, and the information system operation standards of Korea Information Security Agency. We analyzed the suitability of the mobile environment and information system operating instructions, and we compared mobile web, operating environments and the ITIL V3.
