隨著無線網路基礎建設的發展以及網際網路無線上網之趨勢,情境感知應用成為各國資訊發展重要趨勢,傳統GPS系統侷限於各類交通工具未具有網路功能的導航應用中,無法將交通工具即時位置資訊整合至網路服務。
本研究提出以GPS為基礎的情境感知閘道系統運作模式,結合GPS定位技術、SOAP 訊息技術、IPv6網路技術,發展出將GPS定位訊息以SOAP和IPv6封包來傳送的運作模式,進而發展出GPS訊息閘道系統與情境感知應用管理者等模組,為了驗證情境感知閘道系統運作模式,本研究實作出三種情境感知應用包括 「高速公路」、「學校」以及「都市」三種情境應用。
結果顯示GPS定位訊息能有效的交互切換三種情境感知應用,此成果可以提供做為情感知中介軟體技術的重要參考。
With the deployment of wireless network infrastructure, context-aware application becomes one weighty trend of the information technology development around the world. Traditional Global Positioning System (GPS) usually used with Geographic Information Systems (GIS) navigation system in different kind of vehicles do not support network capability for the access of real-time location based information.
In this paper, we present GPS-based context-aware gateway system operation model. It is a new communication model integrated with the technologies such as GPS technology, SOAP message technology, and IPv6 internet protocol. In our communication model, GPS signals are packed into SOAP messages and transmitted by IPv6 packets. Using this communication model, we develop the GPS-message gateway and context-aware application manager. In order to validate our communication model, we introduce three kinds of context-aware application model named “Freeway Model”, “Campus Model”, and “City Model” to be integrated in our communication model.
The result presents that our system can effectively switch GPS signals among above-mentioned applications models, which opens out a wide prospect of context-aware middleware evolution.
