“…6. The main reason is that we synthetically consider link throughput and link lifetime in establishing the standard of the first relay selection (see formula (14)). Based on this standard, if another relay is needed in data transfers, we can ensure that the remaining energy of the second relay is not lower than the minimum value between the first relay's energy and the energy threshold via energy constraint.…”

“…Meanwhile, by using an interference alignment (IA) transmission mode within small scale clusters, D2D users could transmit its data in higher spectrum efficiency. The authors in [14] propose a channel-opportunistic architecture to enhance throughput, energy efficiency, and fairness, in which clusters are formed by cellular UEs and then the UE owning the best channel status is selected as the cluster head to communicate with base station on behalf of the whole cellular UEs. Within clusters, the unlicensed spectrums are used between D2D pairs.…”

“…First of all, we select the two optimal potential relays (lines 9 to 17), then estimate the value of RIE i by formula (14) and compare with the given RIE th . Finally, the optimal relaying UE or sub-optimal relaying UE will be chosen to act as the first relay according to the evaluated value (lines 18 to 20).…”

One goal of the fifth-generation (5G) cellular network is to support much higher data capacity (e.g., 1000 times higher than today), where device-to-device (D2D) communication is one of the key enabling technologies. In this paper, we focus on the D2D relaying functionality to improve cellular downlink throughput. Based on the shortages of the latest relevant work, we propose a new scheme that leverages multi-hop relay-assisted outband D2D communications. First of all, by extending two-hop connection to three-hop connection, our scheme can cut down receiving bit error ratio (BER) of cell edge nodes far away from a cellular base station (BS), which improves cellular downlink throughput. Then, it balances network lifetime and throughput by the proposed ratio of income and expenditure (RIE) metric with respect to remaining energy and throughput. Moreover, it reduces the computational overhead of searching relay and also ensures that the optimal relay is selected by the adjustment of searching scope. Compared with the most relevant work, our scheme outperforms it in terms of throughput, delay, and network lifetime.

“…Driven by a huge increase in demand of multimedia traffic transfer, D2D communication allows saving scarce network resources by transferring data directly between devices either in-band or out-of-band, and D2D communications allow significantly reducing traffic between base station (BS) and end-user device [1].…”

Significant increase in multimedia traffic challenges 5G networks in terms of capacity and correspondent QoS parameters. Deviceto-device communication paradigm has already become an integral part of 3GPP standards; nevertheless it has not yet been widely deployed due to many different reasons. D2D is expected to leverage implementation of many qualitatively new services and to efficiently accomplish it D2D devices are supposed to form clusters. Due to practical limitations, current D2D implementations are mostly out-of-band and use Wi-Fi Direct. In this paper, we propose a novel model for throughput optimization in out-ofband D2D clusters. We delivered numerical results for different typical cluster member distributions and revealed key functional dependencies. Further, for the first time we compare clustering algorithms for out-of-band D2D and identify effective clustering algorithm that increases network resource utilization rate.

Wireless access points and nearby mobile devices usually possess some available computation and storage resources. In the prospective dense wireless networks, these resources could be sufficiently abundant due to a large number of devices. It is critical to investigate how to efficiently distribute the computation and storage burden of local equipment to nearby devices. The corresponding paradigm, proposed by Cisco, is called fog computing. Fog computing cannot survive without the support of ubiquitous communication, which appeals to high‐speed direct communications provided by device‐to‐device (D2D) techniques. This article will discuss the challenges and solutions in integrating D2D into fog computing.
