摘要(中) Wi-Fi Direct標準解決了人們對於點對點IP 網路的需求,軟體商可依此為基礎架構,在其上發展各式服務,其中為了解決服務搜尋問題及避免不必要的連線,Wi-Fi 聯盟自2012 年Wi-Fi CERTIFIED Passpoint™ 後,便積極將802.11u 標準納入Wi-Fi 體系,2014 年8月在Wi-Fi Direct 的基礎上,Wi-Fi聯盟推出Wi-Fi Peer-to-Peer Services (P2Ps)技術標準,提供在Wi-Fi Direct 網路上,進行服務搜尋的規範,而本論文就基於此技術規範,以Android 平台裝置為實驗標的說明封包間如何運作,並於文中率先提出Application Service Platform (ASP)的概念,在應用程式下,應用共通的軟體平台使裝置間得以交換資訊,在裝置找到彼此後,利用平台上對於連線的設定,讓交換憑證自動完成,以實現無使用者介入自動建立連線以交換資訊的目標,在Direct 網路上,實現物聯網萬物互連的可能性。此外,論文採用Android OS 裝置作為實驗標的,基於Android限制提出利用Wlan 介面來進行網路串接以擴展服務搜尋的範圍,並在軟體平台上進行服務資訊的交換,此法不僅適用於Wi-Fi Direct裝置,同時也適用於以802.11 a/g/n Wi-Fi 介面進行網路連線的傳統裝置,讓這些傳統裝置也能透過軟體平台判別服務的來源,以進行後續應用與操作,在最後,我們針對論文中所提出的Wi-Fi Direct 網路串接方式,進行Throughput 評估,以了解裝置在跨網路介面及跨Group後的Throughput變化。
摘要(英) Wi-Fi P2P Technical Spec. provides a simple and convenient way to make IP network connection among Wi-Fi Direct® devices. Under the specification, people could set individual network without apply complex setup. Software vendors could develop solution based on the architecture for some kind of applications, such as print, share, sync, and display. For achieving the service discovery and avoiding unnecessary connection, 802.11u Access Network Query Protocol had been introduced to Wi-Fi system from Wi-Fi CERTIFIED Passpoint™ and Wi-Fi Alliance brought Wi-Fi Peer-to-Peer Services Technical Specification in Aug. 2014 that provide the approach to perform service discovery on Wi-Fi Direct Network. The paper based on the technical spec. to practice packet exchange on Android platform, moreover it implements Application Service Platform concept that would be official released in 2016. With the ASP construction, devices could use the common software platform to exchange information. Besides, the similar concept of WSN and Wi-Fi Aware™ are adopted in this paper. Under the architecture, devices could connect to each other without user intervention, the key exchange would be completed through ASP setttings in automatic way that we can realize Internet of Things (IoT) on Wi-Fi Direct construction.
Additional, non-root Android device could not create multiple GO/GC in the same time so the paper introduce a way to link multiple Direct Group Network through wlan interface for extending the service scope and also, throughput variation evaluated in observation.
