“…However, network coding technologies are not taken into account in these work, which are promising for improving the efficiency of content distribution. In [2] and [10], authors propose a system that maximizes the video quality based on the principles of the cooperation among users with network coding and broadcast in D2D links. Different from previous work, we explore the fast content distribution issue under a general D2D communication model where multiple channels are available and the transmission scheduling is time slotted.…”

Recently, device-to-device (D2D) communications have been leveraged to offload the traffic on cellular networks. In this paper, we focus on the content distribution problem over a hybrid cellular and local D2D network where mobile devices cooperatively download a same content. We assume that the transmissions over D2D communications are scheduled in a centralized fashion so as to achieve a high transmission efficiency. Aiming at minimizing the content download time, we formulate the minimum content download time (MinCD) problem as an integer linear programming problem, and show its hardness and inapproximability. For the case that only a single channel is available for D2D communications, we propose an asymptotically optimal algorithm. For the multi-channel case, we further propose a heuristic algorithm with low time complexity and demonstrate its efficiency via extensive simulations.

“…Several recent studies have shown that intelligent design of cooperative techniques using multiple wireless interfaces for content distribution to a group of users that are within proximity can address the problem of cellular traffic congestion. Moreover, it can also lead to frequency resource savings in wireless networks, and can also lead to more energy efficient wireless networks [9][10][11][12][13]. The practical use cases of wireless content distribution using multiple interfaces that are investigated in different works are (but are not limited to): (1) Devices that access the same content at the same time.…”

In this tutorial paper, we discuss and compare cooperative content delivery (CCD) techniques that exploit multiple wireless interfaces available on mobile devices to efficiently satisfy the already massive and rapidly growing user demand for content. The discussed CCD techniques include simultaneous use of wireless interfaces, opportunistic use of wireless interfaces, and aggregate use of wireless interfaces. We provide a taxonomy of different ways in which multiple wireless interfaces are exploited for CCD, and also discuss the real measurement studies that evaluate the content delivery performance of different wireless interfaces in terms of energy consumption and throughput. We describe several challenges related to the design of CCD methods using multiple interfaces, and also explain how new technological developments can help in accelerating the performance of such CCD methods. The new technological developments discussed in this paper include wireless interface aggregation, network caching, and the use of crowdsourcing. We provide a case study for selection of devices in a group for CCD using multiple interfaces. We consider this case study based on the observation that in general different CCD users can have different link qualities in terms of transmit/receive performance, and selection of users with good link qualities for CCD can accelerate the content delivery performance of wireless networks. Finally, we discuss some open research issues relating to CCD using multiple interfaces.

“…Only a few implementations of DNC in TWRN or larger relay networks are reported in [2], [5] and [6]. For example, [5] demonstrates essential reduction of time required to exchange video files between smartphones, in case DNC is employed. In [2], Katti et al present a new architecture for wireless mesh networks (COPE), which improves the throughput of wireless networks by forwarding DNC mixed packets.…”

Abstract-Network coding is a technology which has the potential to increase network throughput beyond existing standards based on routing. Despite the fact, that the theoretical understanding is mature, there have been only a few papers on implementation of network coding and demonstration of a working testbed. This paper presents the implementation of a two-way relay network with digital network coding. Unlike previous work, where the testbeds are implemented on custom hardware, we implement the testbed on GNU Radio, an opensource software defined radio platform. In this paper we discuss the implementation issues and the ways to overcome the hardware imperfections and software inadequacies of the GNU Radio platform. Using our testbed we measure the throughput of the system in an indoor environment. The experimental results show that the network coding outperforms the traditional routing as predicted by the theoretical analysis.
