遠距照護系統已被視為未來的重要產業之一，本研究透過網路服務，試著整合許多功能於遠距照護系統中，例如，整合多項無線測量儀器與相關的資訊系統，使病患在醫院或居家生活都能獲得完整的照顧。當病患在家休息或是活動時，測量的儀器可隨時透過無線傳輸設備，監控病患的基本生理狀態，如發生異常時，可發出警示訊號提醒，或是自動上網通知親友甚至是醫護單位，以掌握時效；如病患需到院或是線上看診時，醫生可以利用系統平日所記錄之相關生理資訊，協助判別或進行討論。本研究將建置實體環境以進行實驗，在架設真實環境之前，先針對基本的生理監控貼片資料來進行模擬。因該貼片目前可以量測體溫、呼吸與心電圖等生理資訊，因此針對基本資料傳輸狀況進行模擬，針對隱藏節點、暴露節點與存取點建置的相關問題，分別進行模擬實驗，本實驗採用NS2(Network Simulator Version 2)模擬軟體進行，由實驗結果得知，網路服務效能會受到節點運作的模式影響，針對模擬結果提出相關之建議。

Tele-care system is regard as one of important industry in the future. This study tends to integrate many functions in long-distance care system through the web services. For instance, integrating wireless measuring instruments and information systems helps patients in hospitals or at home would have complete care. When patients rest at home or do activities outside, measuring instruments may monitor their basic physiological status through the wireless transmission equipment. If an exception occurs, measuring instruments may issue a warning signal to remind, or inform the relatives, friends and even health care centers through internet automatically in order to save time. Moreover, when patients have to get in hospitals or process online interview, doctors may use the daily recorders to identify or discuss. This study uses physiological monitoring chips to measure status; now the chip can measure body temperatures, respirations and ECG physiological information. The final studies have shown questions of the hidden nodes, exposed nodes and access points. To simulate the experiment, this experiment used NS2 (Network Simulator Version 2) simulation software. Web services performance is impact by modes of node’s operation.
