摘要

行動(穿戴)裝置與無線寬頻網路的快速普及，帶動人們對於行動服務需求與日俱增，囿於行動(穿戴)裝置有限的運算能力、續航力與儲存能力，行動(穿戴)裝置之間必須透過無線網路彼此串連以及與雲端運算結合，方能達到其預期服務效能。然由於行動(穿戴)裝置產品應用多元，各家廠商所開發的行動(穿戴)裝置網路連線平台存在一定程度的差異性，造成行動(穿戴)裝置間溝通整合困難。本研究著眼於克服行動(穿戴)裝置間以及與雲端設備的異質性系統整合問題，包含：(1)資料穩定傳輸(Data Transmission Stability)；(2)異質資料互通(Heterogeneous Data Interoperability)；(3)異類平台支援(Multiple Platforms Adaptation)等問題進行研究。
針對三項欲解決的問題，本研究所提出的方法為(1)資料穩定傳輸：利用訊息導向中介軟體(Message-Oriented Middleware, MOM)提高行動(穿戴)設備傳輸的穩定性、(2)異質資料互通：以「資料類別」(Data Class)作為訊息傳輸單元來提高不同穿戴應用服務的資料互通性、及(3)異類平台支援：使用中介層(Middleware)以適性支援不同類型行動(穿戴)裝置之間傳輸。本研究以中介層技術為基礎，提出一個易於開發各式行動應用軟體的傳輸平台，為行動(穿戴)裝置上執行的應用軟體提供高穩定的訊息傳輸服務、及簡易的訊息處理方式，同時利用中介層技術解決異類平台整合的問題。本研究的設計概念是基於IEEE 1516規格，此規格又稱為高階模擬架構(High Level Architecture, HLA)。HLA規格的基本精神為分散式計算架構，各連線端電腦之間是以「資料類別」(Data Class)方式來互傳訊息。資料類別的概念讓應用軟體更易於管理訊息，且本研究所設計之平台更將資料類別(Data Class)與MOM的頻道(Channel)機制結合，以頻道作為網路應用端之間的訊息傳輸管道。
本研究透過結合上述方法實作行動(穿戴)裝置的互動資訊傳輸中介平台，稱為Taggle Platform。為貼近行動(穿戴)裝置有限的運算能力，此平台是架構在輕量化的IoT MOM軟體 - MQTT。本研究透過實驗以驗證Taggle Platform對於行動應用的傳輸穩定性及行動服務的資料互通性。此外，平台目前實際運行於Android與一般個人電腦，可透過此平台建立一個跨及智慧型手機與主機伺服器的手機服務應用。

Thanks to fast advance of mobie/wearable devices and wireless network technologies, there are more requirements for mobile services. But constraint by their computing speed, battery capacity, and storage size, mobile/wearable devices need to integrate with each other or with the cloud servers to provide acceptable services. And the diversity of mobile/wearable devices makes it difficult to integrate different devices into a single mobile service. This research aim to solve the integration problem between mobile/wearable devices or between wearable device and cloud servers, including: (1) Data transmission stability, (2) Heterogeneous data interoperability, (3) Multiple platform adaptation.
This research uses the following methods to solve the three problems, (1) Data transmission stability: use the mechanism provide by Message-Oriented Middleware to enhance data transmission stability of wearable devices; (2) Heterogeneous data interoperability: use Data Class as transmission unit to achieve heterogeneous data interoperability, (3) Multiple platform adaptation: use middleware service to link different wearable devices. This research bases on middleware service to make a mobile/wearable device transmission platform, to provide high data transmission stability, and simple messaging process way, mean while integrates heterogeneous device.By this platform this research wants to provide an easy way for mobile service developers to develop different mobile services on heterogeneous devices. This research is based on IEEE 1516, also named High Level Architecture (HLA). HLA uses Data Class to make distributed network hosts to transmit messages to other network hosts, which makes it easier to manage the data exchange. This research integrates Data Class and MOM’s channel, use MOM’s channel as messaging medium between different network hosts.
This research by using the method metioned above to implement a mobile/wearable device transmission platform, named Taggle Platform. Due to limited computing power of mobile/wearable devices, this platform use a light-weight MOM software – MQTT. This research uses Taggle Platform to proof this platform can deal with the three problems. Now developers can use personal computers and Android devices join this platform and make an mobile application across different devices.
