若將OSGi平台放置到嵌入式系統上執行，效能的改善是個重要的課題，本論文因此提出OSGi平台(Platform)效能改善方法。OSGi平台之執行包含三個階段，第一個階段是OSGi平台啟動，第二個階段是OSGi Bundle安裝及執行，第三個階段是中止平台執行，此研究裡，將針對第一個階段OSGi平台啟動進行最佳化，並選擇Apache Felix[3]為欲改善之目標平台。在此研究所選擇之測試嵌入式系統上，Felix在改善前需花費八十秒的啟動時間，而在改善後則花費四十秒的啟動時間，最佳化後整體效能提升50%。 Recently, OSGi has been widely adopted to serve a platform on OBU to enable dynamically installing and composition of software modules in telematics domain. It is imperative to investigate the optimization of OSGi platform especially on devices with limited resources, such as an OBU or a handheld device, to better deliver OSGi services in a timely manner. In this work, we select Apache Felix as the target platform and propose numerous optimization techniques. The experiment result shows that the optimized platform can save 50% in its startup time.
