對於高齡化社會而言，利用訊息和通訊技術來提高老年人居家照護服務的智慧化程度(智慧居家照護)，已成為重要的研究課題。儘管家庭存取網路通常建立在有線集線器和無線存取點設備上，但是居家服務的部署僅限於家庭網路的有限通訊範圍內，由於物理上的限制，可能無法存取網際網路，或者無法進行部屬。基於物聯網（Internet-of-Things，IoT）的醫療保健環境系統是在室內完成智慧服務部署的方法之一。在本研究中，我們利用物聯網（IoT）技術以開發智慧居家護理服務，並幫助將即 時訊息分發給居家範圍外的遠端用戶，以擺脫本地端的連接。此外，也為醫療保健系統的發展做出貢獻，以幫助並滿足老年人的需求。我們提出了一種自組織的網路架構，在該架構上，鄰居設備無需透過基礎網路架構即可直接進行跳點連接至中繼站傳輸數據。我們以配有相機的Raspberry Pi model 4 按陣列排列來當作展示。即時媒體串流將從任何相機設備發出，通過中繼設備進行傳輸，最終由位於家庭網路或網際網路上的由管理服務器連接的家庭閘道器接收。我們所提出的自組織網路架構已在具有一定物理和訊號干擾的真實房屋環境中進行測試。結果表明，基於物聯網（IoT）的醫療環境在未來的應用中有望為老年人提供幫助。;Towards the aging society, applying information and communication technologies toadvance the elderly＇s home care services to be smart, i.e., smart home, becomes a significant study topic. Home access networks are generally built-in with wired hubs and wireless access-point equipment. However, the device in home network may not get access to the internet or cannot be connected because of physical limitation such as walls and decoration. Hence, the deployment of home services is confined to limited physical communication coverage of a home network. Using the Internet-of-Things (IoT) technology is an promising approach to accomplish the device and service deployment in the residential environments. In this study, to get rid of local connectivity at home, we contribute to the evolution of the healthcare system in order to assist and serve the needs of the elderly. We take an advantage of IoT-technology to develop smart home care services and get rid of local connectivity to distribute instant information to remote users outside the home domain. We propose a self-organized network architecture on which neighbor devices establish direct hop-to-hop connections and relay data flows without resorting to underlying network infrastructures. Camera-equipped Raspberry Pi model 4 used as demonstration devices are aligned in an array. Real-time media streams will be issued from any source camera, transmitted via a relaying device, and eventually received by a home gateway connecting with a management server that locates on a home network or the Internet. The proposed self-organized network architecture is tested with a real house environment with some physical and signal interference. The results have shown the promising direction of futuristic applications of IoT-based elderly healthcare in smart home space.
