  • 현재 사용되고 있는 위피(WIPI) 콘텐츠 저작 도구는 위피 코드 개발의 편의성이 부족하고, 각 이동통신사 위피 에뮬레이터를 유연하게 지원하지 못한다. 이로 인해 위피 콘텐츠 개발 시 개발 비용이 증가하고, 개발자는 개발 편의성을 제공받지 못하고 있다. 따라서 위의 문제점과 단점을 보완해 줄 수 있는 위피 콘텐츠 저작 도구, 즉 위피 통합개발환경이 필요하다. 본 논문에서는 기본 위피 코드 및 각 이동통신사 에뮬레이터를 WPM(Wipi Platform Management) 에 적용하고, WPM을 기능 요구사항에 반영한다. 그리고 분석된 기능 요구사항을 토대로 시스템 구성을 제안한다. 제안한 도구는 위피 코드 관리 및 각 이동통신사 위피 에뮬레이터와의 유연한 연동을 지원함으로써 개발의 편의성을 높일 수 있다. 또한 제안한 위피 통합개발환경을 이용하면 모바일 게임, 교육 등의 콘텐츠 제작에 효율적이다.

  • 현재 위피 저작도구는 위피 코드 작성의 편의성이 부족하고, 시각화를 배제한 문법 중심의 프로그래밍 도구가 대부분이다. 이로 인해 규모가 작은 위피 응용프로그램의 경우에도 직접 코딩해서 개발하고 있다. 따라서 위피 상위레벨(High level) 컴포넌트를 GUI 위젯(Widget)으로 시각화하고, 이를 모바일 레이아웃에 쉽게 적용한 후, 위피 코드로 렌더링(Rendering) 해주는 저작도구에 대한 연구가 필요하다. 본 논문에서는 위젯, 기본 위피 코드, 에뮬레이터 관리를 위해 W2PM(Widget and WIPI Platform Management)을 제안하고, 이를 시스템 기능 요구사항에 반영하여 GUI 위젯을 이용한 위피 저작도구를 설계한다. 제안한 도구는 개발자가 Look & Feel을 자유롭게 조정하고, 중.소규모의 위피 응용프로그램을 제작하는데 효율적이다.

  • We developed the CNU nt emulator which is an development environment for WIPI applications, wireless Internet applications for cellular phones with the WIPI software platform. The CNU WIPI emulator provides stable memory management and ability of installing, executing, deleting or managing WIPI applications. WIPI WAM provides quick execution of applications and convenient debugging function. In this paper, we describe the design, implementation issues of the CNU WIPI emulator and show its correctness of executing and performance improvement over $25\%$ by comparing it with other WIPI emulators.

  • The abolition of WIPI installation duty makes domestic WIPI developers get a chance to enter into smartphone development environment. Specially, iPhone has a big possibility for a new game application market but traditional domestic WIPI developers have difficulties to get in because there are no standard game development methodology. Therefore, a method is necessary to develop iPhone game application effectively for traditional domestic WIPI developers. In this paper, we compare and analyze development methodology of WIPI and iPhone application and suggest a new methodology for iPhone application development with adaptation of WIPI architectures. Using this methodology, traditional domestic WIPI developers can develop iPhone game applications with ease.

  • At present, Authoring tools, which are used to develop the WIPI applications are less convenient to be coded. Usually, the programming tools only focus on the grammar while scarcity of visualization. Developer forced directly codes all times during the development by this cause. As a procedure for rapid WIPI Application Development, in this paper, WIPI API High Level Component is first visualized, in order words, graphic control is developed. Second this control is used in designing the mobile layout. Then UI Markup Language and source code can be generated automatically. With this view, we propose the JIML(Jlet Interface Markup Language) with UI Markup Language based XML of WIPI Jlet Platform and also present the transformable rule for generation to the WIPI code about WIPI Jlet UI from offered JIML. Also we implement the WIPI Jlet Generation System to make the generation to JIML, WIPI code. The Implemented System provides efficiency when developing WIPI Business Application, and helps to enable rapid development.

  • This paper describes the LBS Terminal Standard Platform based on WIPI. The LBS Terminal Standard Platform based on WIPI is API for obtaining the location information in the mobile standard platform providing the environment which is mounted on the mobile communications terminal and can platform an application. The mobile Platform consists of HAL API, C API and Java API that it is able to process Location Information data among wireless network. It is defined and developed at the HAL sections and C sections based on Generic I/O, and It describes in details in this paper. This standard Platform is expected to be utilized as the base specification in developing the LBS Terminal development technology and standard method to LBS application developers.

  • In this paper, we propose the reference implementation of WIPI runtime engine supporting various platforms such as REX OS, Qplus and Windows. We describe the architecture of WIPI runtime engine according to each platform, and introduce the method for avoiding repetitive develoment. And we explain the implementation of a linker and a loader on REX OS and describe the runtime engine structure on Qplus, a kind of embedded linux. And we introduce the implementation of the Jlet/MIDlet emulator based on a Java virtual machine and the Clet emulator based on Windows. Finally we verify the interoperability and the perfection of the proposed reference implementation through the result of the HCT and the PCT and the normal operation of the example programs.

  • Mobile devices become more complex and harder to manage due to the advance of technologies. In this paper, we designed and implemented the DM Agent based on OMA(Open Mobile Alliance) DM(Device Management) which is a standard for mobile device management. The proposed DM Agent basically can manage parameter configuration through the commands ADD, DELETE, REPLACE and GET currently. Each module of the agent was designed and implemented separately for additional functions such as error reporting and software management. So the additional functions can be added by modifying Adaptor part which processes the management commands instead of modifying other modules which analyze or generate management commands. The DM Agent proposed in this paper is implemented based on WIPI(Wireless Internet Platform for Interoperability), therefore portability of the agent can be improved. In addition, this research can give a development example for dissenminating OMA DM as well as verify functional compatibility of WIPI platform. SK WIPI SDK and a Funambol DM test server are used to test operations of the implemented DM Agent.

  • Performance of the mobile devices greatly depends on the efficient resource management because they are usually resource-restricted. In particular, the dynamic storage allocation algorithms very important part of the mobile device's operating system and OS-like software platform. The existing dynamic storage allocation algorithms did not consider application's execution style and the type, life-time, and characteristics of memory objects that the application uses. Those algorithms, as a result, could not manage memory efficiently Therefore, this Paper analyzes the mobile application's execution characteristics and proposes anew dynamic storage allocation algorithm which saves the memory space and improves mobile application's execution speed. The test result shows that the proposed algorithm works 6.5 times faster than the linked-list algorithm[11], 2.5 times faster better than the Doug. Lea's algorithm[12] and 10.5 times faster than the Brent algorithm[14].
