“…Many researchers have addressed the problem of uploading contents while considering the cache [23][24][25][26][27][28][29][30]. In [23], the authors proposed a mobile video uplink caching algorithm to increase video quality via recover lost video frame in real-time video transmission.…”

“…The upload cache reduced user online time for uploading the content and reduced the peak traffic volume between edge networks and data centers. In [26], the authors designed an upload acceleration service framework for mobile devices on virtual network architecture host-based WiFi as the access point. That architecture is designed in threefolds: upload acceleration service to the designated flow of data, a two-tier architecture where UGC is first cached to the front-end, then to the back-end, finally to the internet.…”

In this era of the digital world, data play a central role and are continuously challenging spectrum efficiency. With the introduction of enriched multimedia user-generated content, the challenges are even more aggravated. In this vein, uplink caching is considered as one of the promising solutions to effectively cater the user’s demands. One of the main challenges for uplink caching is duplication elimination. In this paper, a cache enabled uplink transmission with a duplication elimination scheme is proposed. The proposed scheme matches the mobile’s data to be uploaded with the cached contents both at mobile station (MS) and small base station (SBS). In contrast to existing techniques, the proposed scheme broadcasts the cached contents at an SBS to all the MSs under its footprint. This provides MS an opportunity to exploit the list of cached contents before uploading its data. A MS only uploads its data if it is not already cached at an SBS. This significantly reduces duplication before the real transmission takes place. Furthermore, the proposed technique reduces energy consumption in addition to improving spectral efficiency and network throughput. Besides, a higher caching hit ratio and lower caching miss ratio are also observed as compared to other schemes. The simulation results reveal that the proposed scheme saves 97% energy for SBS, whereas 96–100% energy is saved for MS on average.

“…In addition, both [9] and [10] also divided the upload process in the same way as in [8] and placed cache at the nearby WiFi access points. Specifically, [9] demonstrated that larger contents could save more connection time for users. And [10] proposed a smart offloading mechanism for content uploading and considered the WiFi bandwidth scheduling.…”

“…Then the authors in [8] proposed a upload cache scheme in edge networks to shorten the duration and reduce the peak traffic volume, by dividing the traditional upload process into two phases: from the client to the gateway cache and from the gateway to the destination server. In addition, both [9] and [10] also divided the upload process in the same way as in [8] and placed cache at the nearby WiFi access points. Specifically, [9] demonstrated that larger contents could save more connection time for users.…”

It is starting to become a big trend in the era of social networking that people produce and upload usergenerated contents to Internet via wireless networks, bringing a significant burden on wireless uplink networks. In this paper, we contribute to designing and theoretical understanding of wireless cache-enabled upload transmission in a delay-tolerant small cell network to relieve the burden, and then propose the corresponding scheduling policies for the small base station (SBS) under the infinite and finite cache sizes. Specifically, the cache ability introduced by SBS enables SBS to eliminate the redundancy among the upload contents from users. This strategy not only alleviates the wireless backhual traffic congestion from SBS to a macro base station (MBS), but also improves the transmission efficiency of SBS. We then investigate the scheduling schemes of SBS to offload more data traffic under caching size constraint. Moreover, two operational regions for the wireless cache-enabled upload network, namely, the delay-limited region and the cache-limited region, are established to reveal the fundamental tradeoff between the delay tolerance and the cache ability. Finally, numerical results are provided to demonstrate the significant performance gains of the proposed wireless cacheenabled upload network.

“…There are also studies target on optimizing the last-mile delivery problem, i.e., from the CDN edge server to end user terminal [13], [14], [15]. For data upstream, which is mostly left unattended by legacy CDNs, there are few solutions for improving its performance [16].…”

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 fileuploading 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.
