摘要
隨著科技的發展，人們可以簡單的透過智慧型手機，平板上網，因為流覽器有跨平台的特性，所以基於網頁的服務越來越多，因此人們對於網頁的需求越來越大。根據HTTP ARCHIVE 網站統計近年來網頁內容大小越來越大，如果使用既有的單一代理伺服器減少使用者的網頁存取速度，代理伺服器則需要更多的空間儲存快取檔案，而,網路傳輸負擔也越來越大。 思科提出霧運算概念，賦予了靠近使用者端的機器有更好的運算能力，儲存能力，讓使用者的需求能夠在近端的機器就能夠被服務或被計算，因此能夠減少回應速度和減低雲端伺服器的負擔。 而本研究為了讓使用者有更好的網頁體驗，提出一個基於霧運算概念之網頁內容分享的系統，本系統改良既有的代理伺附器管理控制小區域間使用者的機器。 本系統利用使用者分享之空間存放快取資料和透過改良過的主代理伺服器之引導，因此使用者間之機器可以透過第二個高速無線傳輸技術互相分享快取資料。本研究實驗中證實基於霧運算之網頁內容分享系統中的代理伺服器並不需要大量的空間並,改善了一小區域間使用者的網頁存取速度。

With the advance of technology and high popularization of Internet, people can easily surf on Internet with smart phone, tablet, etc. Because of the property of cross-platform of browser, there are many kinds of web-based service. The need of Internet service of people is more and more. According to statistics of HTTP Archive org, web content is bigger and bigger. If we use normal single proxy to reduce the response time of user, proxy needs more storage to store cache file and power of transferring ability. Cisco proposed a new vision of network. It called fog computing. The main idea is to bring the device at the edge of network ability to computing, caching, powerful features so request from user can be computed and be processed by devices at the edge of network for response reduction [1] [2]. In our proposal, we want users have better experience of web, so we propose web document sharing on fog computing system. We implement our system which is applicable in a small area with a present normal proxy for controlling and management request from users. However, web content is bigger gradually burdens present proxy. It needs more space to store cache files, and powerful transferring ability. Thus, our system is proposed to improve performance and reduce cost. Our proposed system utilize the space of user local storage to store cache data share with each other among users with a short distance communication channel. In our experiments, we verify our proposed system has better performance than present normal proxy without using much storage.
