Device-to-Device Networking Meets Cellular via Network Coding

Abstract

Utilizing device-to-device (D2D) connections among mobile devices is promising to meet the increasing throughput demand over cellular links. In particular, when mobile devices are in close proximity of each other and are interested in the same content, D2D connections such as Wi-Fi Direct can be opportunistically used to construct a cooperative (and jointly operating) cellular and D2D networking system. However, it is crucial to understand, quantify, and exploit the potential of network coding for cooperating mobile devices in the joint cellular and D2D setup. In this paper, we consider this problem, and (i) develop a network coding framework, namely NCMI, for cooperative mobile devices in the joint cellular and D2D setup, where cellular and D2D link capacities are the same, and (ii) characterize the performance of the proposed network coding framework, where we use packet completion time, which is the number of transmission slots to recover all packets, as a performance metric. We demonstrate the benefits of our network coding framework through simulations.

Cooperative Admission Control with Network Coding in 5G Underlying D2D-Satellite Communication

“…However, 5000 iterations are used for the MANC algorithm to cater for all possible combinations of packet missing. First, the ATSPSN algorithm is compared, followed by the JAMANC algorithm, and a comparative study is carried with the MANC standalone (extended NCMI algorithm proposed in [5]) and ATSPSN standalone algorithm [25]. Moreover, mode analysis is done.…”

“…As per International Mobile Telecommunications 2020 (IMT-2020) guidelines [30], the significant key performance indicators (KPIs) for the 5G network is capacity, energy efficiency, and fair usage policy. The time required to complete the packet completion is a critical factor in analyzing the network coding [5]. Earlier packet completion time leads to better performance of the network.…”

“…Now, the JAMANC algorithm's comparison is made with standalone techniques (ATSPSN/ MANC) and standalone modes (cellular/D2D/satellite). MANC is an extended version of the NCMI (Network coding multiple interfaces) proposed in [5] with satellite included apart from D2D-cellular communication. The quantitative performance is compared with theoretical bounds derived during problem formulation section in terms of packet completion time.…”

“…The cooperative network coding then extended to the device to device (D2D) communication, which further increases the overall capacity and throughput of the network [2][3][4]. The utilization of D2D and cellular network in network coding decreases the packet recovery time, and meets the performance of cellular via network coding [5]. Satellite multicast delivery is superior to multi terrestrial cast in the number of scenarios because of the bigger footprint [6].…”

Multi-Hop D2D Communications With Network Coding: From a Performance Perspective

“…It is known that network coding is capable of improving network throughput performance by allowing relay nodes to compute and then forward the received packets [7], [8], [9]. Generally speaking, the techniques of network coding can be divided into the following major categories [10]: physical layer network coding (PNC), analog network coding (ANC), instant decodable network coding (IDNC), and random linear network coding (RLNC).…”
