This paper provides a report about a framework that uses a variety of standards. Readers interested in 3D computer graphics or component-oriented technology in C++ will find a report about the integration of various standards by relying on yet another standard for component-oriented software engineering. The highly successful Java standard called Open Services Gateway initiative (OSGi) is employed in a C++ implementation called Open Service Platform.The application of this standard, which is primarily focused on network-centric software and embedded systems, in the field of real-time 3D computer graphics, provides novel insights into the usability of the OSGi standard. 相似文献

With the enormous market potential of the telematics industry and the rapid development of information technology, automotive telematics has attracted considerable attention for mobile computing and Intelligent Transport Systems (ITSs). However, as a result of varied platform standards, not all telematics services can be used in telematics terminals. The main issues are that most telematics technologies depend on vertical, proprietary, and closed Original Equipment Manufacturer (OEM) platforms. These platforms form islands of non-interoperable technology and prevent third-party service providers from creating valuable services. This study integrates the Open Gateway Service Initiative Vehicle Expert Group (OSGi/VEG) into an Android platform to generate a vehicular Android/OSGi platform that has the advantages of both original platforms. These features include remote management, rich class-sharing, proprietary vehicular applications, security policies, easy management of Application Programming Interface (APIs), and an open environment. This study also integrates a cloud computing mechanism into the Android/OSGi platform, allowing service providers to upload their telematics bundles onto storage clouds using a provisioning server. A management agent in the Android/OSGi platform can simultaneously update its application service modules using remote storage clouds and use visual intelligence to continually change the distinguishing features of applications based on context-awareness without user intervention. To assess the feasibility of the proposed Android/OSGi platform, this study presents a vehicular testbed to determine the functionalities of different telematics applications. Android/OSGi platform applications require less memory and system resources than those on the original Android platform when performing complicated operations. Additionally, the Android/OSGi platform launches telematics services more quickly than the original Android platform. The proposed platform overcomes the problem of frequent non-responsive exceptions in the original Android platform. 相似文献

基于OSGi 的移动广告平台订单系统 总被引:1,自引:1,他引:0
基于组件化构建应用已经成为一种趋势。针对模块划分缺少理论依据和指导,提出了依靠软件数据模型进行细粒度划分基本单元,再根据组件之间的服务交互频度和权值对基本单元的相关性进行分析,最终,利用模糊图的聚类方法,将基本单元聚类成模块的模块划分方法。最后,通过基于OSGi(Open Services Gateway Initiative's framework)的移动广告平台订单系统的应用实例表明了该方法的合理性和有效性。该模块划分方法适用于简单的面向数据模型的应用系统。 相似文献
