“…In [12], authors consider multihop D2D communications in order to extend the network coverage and propose a resource allocation strategy to optimize the throughput along the multihop paths. The study is restricted to two-hop communications where one UE is identified as relay node for one pair of transmitting and receiving UE, where each hop is a unicast point-to-point (P2P) D2D transmission.…”

A Fast and Reliable Broadcast Service for LTE-Advanced Exploiting Multihop Device-to-Device Transmissions

Several applications, from the Internet of Things for smart cities to those for vehicular networks, need fast and reliable proximity-based broadcast communications, i.e., the ability to reach all peers in a geographical neighborhood around the originator of a message, as well as ubiquitous connectivity. In this paper, we point out the inherent limitations of the LTE (Long-Term Evolution) cellular network, which make it difficult, if possible at all, to engineer such a service using traditional infrastructure-based communications. We argue, instead, that network-controlled device-to-device (D2D) communications, relayed in a multihop fashion, can efficiently support this service. To substantiate the above claim, we design a proximity-based broadcast service which exploits multihop D2D. We discuss the relevant issues both at the UE (User Equipment), which has to run applications, and within the network (i.e., at the eNodeBs), where suitable resource allocation schemes have to be enforced. We evaluate the performance of a multihop D2D broadcasting using system-level simulations, and demonstrate that it is fast, reliable and economical from a resource consumption standpoint.

Abstract-The joint scheduling of cellular and D2D communications to share the same radio resource is a complex task. In one hand, D2D links provide very high throughputs. In the other hand, the intra-cell interference they cause impacts on the performance of cellular communications. Therefore, designing algorithms and mechanisms that allow an efficient reuse of resources by the D2D links with a reduced impact on cellular communications is a key problem. In general, traditional Radio Resource Management (RRM) schemes (D2D grouping and mode selection) focus on finding the most compatible D2D pair for an already scheduled cellular User Equipment (UE). However, such approach limits the number of possible combinations to form the group (composed by a cellular UE and a D2D pair) to be scheduled in the radio resource. To overcome that, in this work a unified Joint Opportunistic Scheduling (JOS) of cellular and D2D communications, which is able to improve the total system throughput by exploiting the spatial compatibility among cellular and D2D UEs, is proposed. But more complexity is brought to the scheduling problem. Thus, a low-complexity suboptimal heuristic Joint Opportunistic Assignment and Scheduling (JOAS) is also elaborated. Results show that it is possible to reduce the computational complexity but still improve the overall performance in terms of cellular fairness and total system throughput with less impact on cellular communications.Index Terms-LTE, network-assisted device-to-device communications, D2D, radio resource management, RRM, proportional fair, grouping, mode selection, joint opportunistic scheduling.

Background: Dealing with Additional Interference BY enabling direct and low-power communication among users, hereafter generally referred as User Equipments (UEs), Device-to-Device (D2D) communication leads to an improved spectrum utilization, system capacity and/or Quality of Service (QoS) levels; and at cell boundaries, D2D links may be used as relays to extend the coverage area [1], [2].Due to their aforementioned advantages and deployment flexibility, D2D communications are considered in 3rd Generation Partnership Project (3GPP) to facilitate Machine-Type Communication (MTC)/proximity aware services, and security/public safety applications, becoming part of Long Term Evolution (LTE) standards [3]. In this context, conventional cellular and D2D communications can be respectively referred as primary and secondary communications.The authors are with Wireless Telecom Research Group (GTEL) at Federal University of Ceará (UFC), Fortaleza, Ceará, Brazil.

“…In addition, D2D communications in a cellular network are controlled by network operators. As a result, D2D communications in a cellular network typically assume 1-hop or 2-hop relay [5,10]. However, to fully utilize the potential of D2D communications, providing multihop D2D networks that operate autonomously is highly required.…”

Device-to-device (D2D) communications are expected to offload cellular networks and enhance public safety. In addition to the capability of direct communication between devices, the capability of delivering data over multihops in an ad hoc manner by autonomous decision of each device is highly desired to expand application areas of D2D communications. To address this issue, we propose a fast and energy efficient D2D multihop routing method using the geographic locations of nodes. To expedite data delivery while saving transmission powers of nodes, we devise the next hop selection method considering the congestion levels of potential next hops. In addition, we devise a detour scheme to move around a routing hole that is encountered when a node cannot find a neighbor that is closer to the destination of a packet than itself. We also propose management procedures so that each node acquires the locations of destinations and its neighboring nodes. Through extensive simulations, we validate the proposed method by comparing the performance of the proposed method with those of maximum progress method (MaxP), cost over progress method (CoP), and congestion-aware forwarder selection method (CAFS). Even though the number of hops obtained by the proposed method is larger than those obtained by MaxP and CAFS, our method is superior to them in terms of the probability of successfully delivering packets to destinations and total amount of energy consumption. We also show that our method can reduce end-to-end delay considerably compared with CoP.
