摘要

本研究提出一個用於異質網路的整合架構，此架構以資料庫為中心，搭配非同步的概念來橋接感測網路與網際網路的一個整合架構。並以互動式的網頁介面，提供使用者瀏覽遠端生理參數以及遠端控制感測節點的狀態。主要的架構分為三個部分，第一部分由不同類型的感測節點所構成的無線感測網路，第二部分為資料伺服器，第三部分為使用者介面。
感測節點所量測到的生理參數與感測節點本身的狀態經由無線感測網路傳送至閘道器，閘道器將接收到的資料傳送到遠端伺服器並儲存於資料庫中，並可將資料傳送到遠端的資料伺服器儲存。使用者以網頁式使用者介面透過瀏覽器即時觀看感測器所量測到的生理參數，並隨時控制感測器狀態。
本研究提出的整合架構主要特色在於以資料庫作為橋接感測網路與網際網路的媒介，以資料驅動作的方法搭配非同步的概念，可以有效橋接感測網路與網際網路，並且降低直接由網際網路存取感測網路的程式設計複雜度，節省系統建置與開發時間，又兼具彈性與相容性，未來連接其他新的感測網路架構，也不需重新設計資料庫或使用者介面。除此之外，在本研究中也以實驗測試此架構在多人同時使用的資料傳送即時性與資料正確性，顯示本整合架構的確可以適用於實際的網路應用中，達到整合異質網路間資料傳輸的目的。

In this study, we propose an integration architecture for heterogeneous network. The asynchronous concept combined with database-centralization was adopted for bridging sensor networks and the Internet. Interactive Web-based user interface was built to provide users with remote physiological signals monitoring and remote control of nodes. The architecture is divided into three parts: the first part is wireless sensor network consisting of various sensor nodes; the second part is the database server; and the third part is the user interface (UI) and the database.
The physiological signal measured by sensor can be transmitted to the gateway via wireless sensor network. Then the data received by gateway can be transmitted to database server and stored in database. Users can monitor the real-time physiological data by browser using the Web-based user interface. And users can control the status of sensor node remotely.
The main innovation of integration architecture is the database-centralization and data-driven concept. It bridges sensor networks and the Internet using the asynchronous concept. This architecture can reduce the complexity of network programming by avoid direct data transmission between Internet and sensor network. Besides, it can reduce the development cost and time, and it has both flexibility and compatibility. It also needs not to redesign the database or user interface while connecting to other network. In addition, we also conducted an experimental test of performance for this architecture. The results showed that the integration architecture has advantage while being applied to the actual Internet applications to transmit data between heterogeneous networks.
