隨著資訊科技的發展，人們的生活相對的越加便利。本論文將設計與實作一雲端環境下Web2.0 品質感知跨網設備調適服務(Web 2.0 QoS Aware Semantic Web Services for Cross-LAN Appliances in the Cloud Environment, WALNUT)，使用者可在無空間限制的情境下整合近端及遠端設備。WALNUT由行動使用者(Mobile users)、整合式家電服務伺服器(integrated appliance service server, IASS)及雲端環境(Cloud environment)所構成。WALNUT建立於Devices Profile for Web Services (DPWS)、開放式服務閘道平台(Open Services Gateway initiative, OSGi)、雲端環境及Web2.0 技術的基礎之上。使用者可利用手持裝置透過雲端環境連接遠端裝置。當整合式家電服務伺服器找尋到新家用設備，家用設備將會被註冊到雲端環境中。雲端環境將會根據家用設備所提供的資訊，記錄其相關資料及服務。透過雲端環境，WALNUT提供推論引擎用於推論使用者的行為並自動控制家電。所有傳送的訊息建立於Simple Object Access Protocol (SOAP)及Web Services Description Language (WSDL)的標準之上。此外，在QoS的部分，在本論文針對不同使用者的裝置設計並提出一Web 2.0品質服務感知的配對方式(Web2.0 qualIty of Service-aware matching, WIST)。在跨網的部分，本論文針對設備及雲端環境的溝通，設計與提出一建立於DPWS為基礎的設備橋接機制(DPWS-based Device Bridge Mechanism)。論文的實驗結果顯示WALNUT可以提供最適當的內容給使用者，並可在最短的時間進行遠端及近端設備的溝通。

With the rapid progress of information techniques, people should have a relatively convenient environment and life. This study designs and develops the Web 2.0 QoS Aware Semantic Web Services for Cross-LAN Appliances in the Cloud Environment (WALNUT) for users to integrate locally and remotely devices without space constraint. WALNUT is composed of Mobile users, integrated appliance service server (IASS) and the Cloud environment. WALNUT is based on the standards of Devices Profile for Web Services (DPWS), Open Services Gateway initiative (OSGi), Cloud environment, and Web2.0 techniques. Users can use handheld devices to connect with remotely devices from the Cloud environment. When IASS finds a new home-appliance, this home-appliance will be registered into the Cloud environment. The Cloud environment records related information and services which are provided by this home-appliance. Through the Cloud environment, WALNUT provides an inference engine to predict the actions of users and control the home-appliance. All delivered messages are based on Simple Object Access Protocol (SOAP) and Web Services Description Language (WSDL). Furthermore, for the Web QoS strategy, this study designs and proposes an Web2.0 qualIty of Service-aware maTching (WIST) model to satisfy different characteristics of users’ requirements. For the cross-LAN strategy, this study designs and proposes a DPWS-based Device Bridge Mechanism to communicate between the cloud environment and devices. Experiment results show that WALNUT can provide appropriate contents and communication between locally and remotely devices with low response time to users.
