Abstract-Device-to-device (D2D) communication, which enables direct transmissions between mobile devices to improve spectrum efficiency, is one of the preferable candidate technologies for the next generation cellular network. Network coding one the other hand is widely used to improve throughput in ad hoc networks. Thus, the performance of D2D communications in cellular networks can potentially benefit from network coding. Aiming to improve the achievable capacity of D2D communications, we propose a system with inter-session network coding enabled to assist D2D transmissions. We formulate the joint problem of relay selection and resource allocation in network coding assisted D2D communications, and obtain the overall capacity of the network under complex interference conditions as a function of the relay selection and resource allocation. To solve the formulated problem, we propose a two-level de-centralized approach, which solves the relay selection and resource allocation problems alternatively to obtain stable solutions for these two problems. Specifically, a coalition formation game and a greedy algorithm based game are utilized to solve these two problems, respectively. The performances of the proposed scheme is evaluated through extensive simulations to prove its superiority.

“…First, we will explore the interplay between the proposed solution and opportunistic routing techniques [5,18]; these have been shown to yield significant enhancements over wireless mesh networks and we expect that their combination with the RLC scheme would be also beneficial, based on the preliminary results that have been discussed in this paper. Another line would be the integration of on-the-fly decoding, as proposed by Sorensen et al [25]; these would allow decoding some packets before the coding matrix is complete, thus reducing the latency.…”

Providing Reliable Services over Wireless Networks Using a Low Overhead Random Linear Coding Scheme

et al. 2016

In this work, we propose a novel intra-flow network coding solution, which is based on the combination of a low overhead Random Linear Coding (RLC) scheme and UDP, to offer a reliable communication service. In the initial protocol specification, the required overhead could be rather large and this had an impact over the observed performance. We therefore include an improvement to reduce such overhead, by decreasing the header length. We describe an analytical model that can be used to assess the performance of the proposed scheme. We also use an implementation within the ns-3 framework to assess the correctness of this model and to broaden the analysis, considering different performance indicators and more complex network topologies. In all cases, the proposed solution clearly outperforms a more traditional approach, in which the TCP protocol is used as a means to offer a reliable communication service.

“…To do so, we proposed CORE [12], a network coding protocol that bridges the concepts of intra-flow and inter-flow network coding. Although, [13], [14] suggested a combination of intra-flow and inter-flow NC, their proposals did not merge them, but rather used them at different layers.…”

We characterize the performance of intra-and inter-session network coding (NC) in wireless networks using real-life implementations. We compare this performance to a recently developed hybrid approach, called CORE, which combines intra-and inter-session NC exploiting the code structure of the former to enhance the gains of the latter. We first motivate our work through measurements in WiFi mesh networks. Later, we compare state-of-the-art approaches, e.g., COPE, RLNC, to CORE. Our measurements show the higher reliability and throughput of CORE over other schemes, especially, for asymmetric and/or high loss probabilities. We show that a store and forward scheme outperforms COPE under some channel conditions, while CORE yields 3dB gains.
