Wi-Fi Direct 下基於XML服務導向架構與廣播串流之通用集成平台

Abstract

近年來，物聯網應用成長快速，有許多的產品已被部署於對等通訊之中，使用高容量傳輸協定來傳輸其服務。相對於現行的一些對等通訊協定，無線直通協定 (Wi-Fi Direct) 有更多的優勢，利於物聯網應用的開發與發展。例如: 高傳輸、傳統無線網路連接功能的兼容性、跨產品支援。因此，無線直通協定已經成為對等通訊中的主流協定。 在本篇論文中，我們提出一個無線直通協定下基於XML服務導向架構與廣播串流之通用集成平台，主要利用服務導向架構 (SOA) 和即時串流協定 (RTSP) 兩大架構設計規劃這個通用集成平台，所謂服務導向架構是一種架構模型，由Web服務技術等標準化元件組成，目的是建立具有彈性、可重複使用的整合性介面，透過如HTTP、XML、SOAP 等產業標準開放式協定，可以不必擔心服務使用什麼平台、什麼技術來建立，也可以輕易進行服務更換或更新。在本文最後，我們評估本系統架構之有效性和可行性，並且依據本架構，實作多個服務內容應用於導遊系統之上，服務內容包括：即時影音串流功能、多頻道語言廣播功能、透過Web Server做即時資料分享功能和雲端資料監控功能。

In recent years, Internet of Things (IoT) applications has increased rapidly. Many products were deployed for some services based on the high volume transmission thru peer-to-peer communication. Compared with the others P2P communications, Wi-Fi Direct has the comparative advantage for IoT applications, e.g. high-speed transmission and Wi-Fi feature compatibility and cross-platform supporting. Wi-Fi Direct has become a main stream for peer-to-peer communications. In this thesis, we propose a universal integrated platform using XML-based SOA and broadcast streaming over Wi-Fi Direct Network. It includes the base components of Service-Oriented Architecture (SOA) and Real-Time Streaming Protocol (RTSP), The Service-Oriented Architecture is an architectural model, and it is standardized components from the Web services technology. E.g. Extensible Markup Language (XML), Simple Object Access Protocol (SOAP) and HyperText Transfer Protocol (HTTP). At the end of this thesis, we evaluate the feasibility and effectiveness of using our proposed scheme and base on its architecture to implement a simple tour guide system. The function includes RTSP live streaming, Multi-channel broadcasting, Real-time content sharing and Cloud content monitoring.
