摘要

至今已無線感測器的種類已越來越多，而無線感測網路的通訊協定也日趨繁雜。大多數的感測器都是為了解決單一種問題或達成單一種功能而設計，因此所能提供的服務種類有限。但在實際應用上，生活中仍存在著許多隱含或是在某種狀態下才需要的服務，要達成這些服務，必須要許多不同種類，不同位置的感測器與制動器才能達成。而數位家庭閘道在聚集或傳遞、交換資訊上則扮演著舉足輕重的角色。在本文中將會介紹JSALearningFramework，其為一個在OSGi框架上的一個協同框架，這個框架利用虛擬裝置的概念達成與實體裝置的通訊，並且還可以自動的依照各種裝置之間的操作與訊息建立出服務建構的藍圖，而此服務藍圖會隨著狀況不同而改變。

Various wireless sensors are developed today and are applied in various applications like providing geometry information, or smoke detection. There are also various wireless protocols to support the communications in wireless sensor networks. Most sensors are designed to have certain functionalities for some purposes. But there are still various implicit and condition-dependent services in real world applications. Many types of sensors and reactors have to cooperate with each other to provide these kinds of services. The home gateway connected with those sensors and reactors play the role of aggregating the information and forward it to the corresponding reactors. In this paper, a co-framework called JSALearningFramework based on the OSGi framework, Open Service Gateway initiative, is introduced. The framework has the ability to communicate with physical devices from their corresponding virtual devices. Furthermore, the framework can also automatically build up a service blueprint which comprises a set of potential services in digital home. Those potential services are learned from family member's responses detected by sensors or operations from interactive devices. The framework constructs a dynamic services platform. By benefiting from OSGi, the lower level of existing protocols can be dynamically updated or extended. The virtual devices and device level services can be handled by the JSALearningFramework with all OSGi features remained.
