自1990年中期互联网商业化以来，由于创新的在线服务的蓬勃发展，人类文化发生了巨大的变化。为了科普网络服务提供商有效且高效地向其客户端递送内容和服务的需求，已经开发了内容分发网络技术。这些技术已经过优化，可以将数据从服务器传输到用户。它并不意味着支持移动的用户通过社交网络服务上传和与他/她的同龄人共享实时捕获的多媒体内容。当前的网络更难以支持移动的用户在热门社交事件中将现场图片和视频真实的分享到他们的社交网络。在本文中，我们提出了我们的设计智能卸载代理（SOP）服务的无线内容上传人群事件。为了测试SOP的效率，我们模拟了一个移动的网络环境，其中无线接入网络通过长途WAN连接到目标社交网络服务器。初步实验表明，在WAN中错误率为1%的情况下，当54 Mbps WIFI媒体被以10秒的到达间隔时间随机到达的用户同时访问时，移动的用户在上传10 MB文件时可能经历大约100秒的长文件上传时间。相比之下，如果WIFI负载较轻且WAN无错误，则上传文件所需时间不到10秒。我们还表明，通过适当地调度WIFI带宽的移动的用户，文件上传时间可以减少。
Since commercialization of the Internet in mid-1990, human culture has changed dramatically due to booming of innovative online services. To cope with demands of network service providers to effectively and efficiently deliver contents and services to their clients, content distribution network technologies have been developed. These technologies have been optimized to transfer data from servers to users. It is not meant to support mobile users to upload and share real-time captured multimedia contents with his/her peers through social network services. It is even more difficult for the current network to support mobile users in a hot social event to shared live pictures and videos to their social network in real time. In this paper, we present our design of smart offloading proxy (SOP) service for wireless content uploading over crowd events. To test efficiency of SOP, we simulate a mobile network environment with wireless access network connected through a long-haul WAN to the target social network server. Preliminary experiments show that with an error rate of 1 % in the WAN, a mobile user may experience long file-uploading time of approximately 100 seconds in uploading a 10 MB file when a 54 Mbps WIFI media is simultaneously accessed by users randomly arrived at the inter-arrival time of 10 seconds. In contrast, it takes less than 10 seconds to upload the file if the WIFI is lightly loaded and the WAN is error free. We also show that by properly scheduling WIFI bandwidth to the mobile users, the file-uploading time can be reduced.
