NC-CELL: Network coding-based content distribution in cellular networks for cloud applications

Abstract

Abstract-The popularity of cloud applications surged in the last years. Billions of mobile devices remain always connected. Location services, online games, social networking and navigation are a just few examples of "always on" cloud applications in which the same or partially overlapping content is delivered to multiple users. In this paper, we propose a technique, called NC-CELL, which uses network coding to foster content distribution in mobile cellular networks. Specifically, NC-CELL implements a software module at mobile base stations (or eNodeBs) which scans in transit traffic and looks for opportunities to code packets destined to different mobile users together. The proposed approach can significantly improve cell throughput and is particularly relevant for delay tolerant content distribution.

Energy-Efficient Computation Offloading for Wearable Devices and Smartphones in Mobile Cloud Computing

“…Direct connection with the cloud avoids communication over the timeconsuming LTE network at the expense in energy consumption. Because of the need to cross the Evolved Packet Core (EPC) network [30], communications over LTE are time consuming and it becomes clear comparing the cases (w-s) and (w-s-c) in Fig. 6(a).…”

“…When these requests come from devices in geographical proximity, they are likely to be served by the same base station. Combining such data flows at the base station has great potential to save network resources [12] and network coding is a well-matching solution for this.…”

Network-assisted offloading for mobile cloud applications

“…Network coding is proved to improve network throughput and is a widely used technique in mobile networks nowadays. Recently, a technique that improves content distribution of mobile cloud applications by combining traffic flows has been proposed for cellular networks [8]. Traffic offloading to other networks can help to avoid having additional cellular network equipment.…”
