摘要(中)

近年來越來越多內含智慧軟體的資訊家電已成為人們生活中不可或缺的一部分，用以開發此類裝置上的軟體服務所採用的OSGi (Open Service Gateway initiative)技術日益獲得注目，然而OSGi技術規格中規範OSGi平台上所提供的服務只能給該平台上的Bundle使用，無法將該平台的服務提供給外部Bundle使用。儘管已有許多的研究提出各種的通訊機制以使用遠端的OSGi服務,但是這些方法仍無法說明在移動計算上的兩個重要議題：(1)移動裝置上有限的資源與(2)移動裝置對外不穩定的網路連線。為了說明此重要議題，我們提出了以旅程驅動之移動代理人方法以遞送分散式的 OSGi服務,其特性包含：
(1)實作以OSGi Bundle為基底的移動代理人,用以遞送分散的OSGi服務同時降低行動裝置上資源的消耗。
(2)擴充WSDL與BPEL以協助開發者設計移動代理人之旅程規劃。
(3)提供服務配對機制讓移動代理人可以動態調整以適應執行環境的改變。
(4)發展非同步通訊機制讓移動代理人在無固定IP與不穩定網路連結的行動裝置間可以可靠的移動。
我們同時製作一系列的實驗以評估系統效能，其結果顯示我們方法在網路資料傳輸量、往返時間與記憶體使用上皆優於主從式架構方法。

摘要(英)

In recent years, as more and more Information Appliances devices embedded with intelligent software have become part of daily life, OSGi (Open Services Gateway initiative), an open service-oriented framework, has gained increasing attention in the development of services for such devices. However, services residing in an OSGi platform are devised
specifically for the platform’s local bundles. Although several work have enhanced OSGi with various communication mechanisms that enable remote service invocations, two crucial issues specific to mobile computing remain to be addressed: 1) the limited resources of mobile devices, and 2) the unstable links experienced by mobile devices. To address these two issues, we propose an itinerary-driven mobile agent approach, including 1) to implement mobile agents as OSGi bundles to deliver distributed OSGi services with lower resource consumption for mobile devices; 2) to extend WSDL and BPEL to help developers design mobile agent itineraries; 3) to provide an opportunistic service matchmaking mechanism that allows mobile agents to adapt to context changes at runtime; and 4) to devise asynchronous
communication mechanism to enable reliable mobile agent transmissions among OSGi-based mobile devices with only dynamic IP addresses and intermittent connection to the Internet. Empirical evaluations are also conducted, and the results show that the performance of our approach is superior to that of centralized client-server approaches with respect to network traffic, turnaround time, and memory usage.
