無線網路監控目前沒有太多相關的研究發表，基於此本研究藉由昇陽公司所發佈最新的Java技術 – Java 2 platform, Micro Edition (J2METM)來探討一些相關的網路監控議題，並結合網際網路，實作出一套遠端監控平台，名為行動資訊服務系統 (Mobile Information Service System)，以提供使用者一個更便利的操作環境。 本研究系統包含：伺服端 (Server-side) 及客戶端 (Client-side)。在伺服端，架設一台影像擷取裝置(Web-cam)來監控伺服器前的影像，而在客戶端則是利用最新的行動裝置開發套件Mobile Information Device Profile (MIDP)，來開發無線應用服務程式。使用者只需透過本無線應用服務程式，下載至手邊的行動裝置 (例如:手機、PDA)，再搭配本系統使用，可以有效地監控架設在遠端伺服器上webcam所擷取到的影像。另外，此系統除了無線遠端監控的功能外，還提供了行動學習的服務，藉由此系統，使用者可以很有效率地去存取網路上各類的資訊，以達到行動學習、學習無障礙的最終目標。 本系統最大的優點在於完全不受平台種類的限制，而可以輕易的移殖至任何系統平台上執行，除了充份的展現跨平台的特性外，更可以減少額外開發所需的成本。而且，經由實驗結果的証明，本系統所提供的服務 (無線遠端監控、線上字典查詢)，在使用上非常方便，極具行動性，完全不受時間及空間上的限制。 As the result of there are not so many researches and publications on the remote monitoring wireless network at present. Hence, this thesis used the newest Java technology – Java 2 Micro Edition (J2ME) to implement a remote monitoring platform, named “Mobile Information Service System”. It provides a more convenient operation environment for the user. The framework of this system can be categorized into two parts: Server-side and Client-side. On the Server-side, there is an image capture device (Web-cam) was set up on the web server. Beside, the wireless service applications were implementing by the latest mobile developing package – Mobile Information Device Profile (MIDP). The user just needs to download these wireless service applications on the mobile device. Through this system, user not only can remote monitoring the server’s states but also can access varied information from the Internet at anytime, anywhere. The most advantage of the system is the cross-platform capability. The system and the wireless service applications can be deploy on any other platforms and devices easily. This capability can reduce the extra development time and cost, and further, the experiment result also demonstrates that the system indeed can work perfect and efficient.
