“…Since the inter-site distance is short, it would be convenient to allow the APs to connect to each other [30]; they would automatically discover and establish the backhaul links. If multiple hops [29,31] on wireless AP to AP links are possible, only a fraction of the APs have to be connected to the core network via a fiber-optic cable, the rest of the APs would act as relay [32] nodes, thereby greatly reducing deployment cost. A multi-hop backhaul network can be used both outdoors and indoors.…”

In recent years, mobile access networks operating at millimeter wavelengths have received a great deal of attention, as they promise previously unattainably high mobile data rates. At these frequencies, mobile access links are expected to use highly directional beamforming antennas, which are also well suited to backhaul links. Therefore, access points can efficiently act as self-backhauled relays by using the same spectrum, circuits and antennas for mobile access and backhaul links, thus forming a multi-hop in-band backhaul network. The contributions of our paper are extensive simulations to investigate user level performance in such multi-hop networks. We specifically take into account the momentary data traffic of every link in order to calculate the interference. Results quantify the detrimental effect of interference on user level performance. Furthermore, the potential benefit of using the combination of in-band and dedicated backhaul links is evaluated. Additionally, this paper investigates the user level effects of the sudden loss of a link in the backhaul mesh network, and underlines the importance of effective rerouting algorithms. The feasibility of the inband concept is demonstrated, and we can confirm that the user level experience will surpass the performance provided by previous generation mobile networks.

“…It has been shown via simulations in [14] that the error due to such an approximation (LOS step model) is generally small in dense mmWave networks, which also motivates the use of this first-order approximation of the LOS probability function which simplifies the dense network analysis. As shown in [14, Fig.…”

“…In this regard, thinning with respect to fading is considered in [35] and [34], while thinning considering blockages is analyzed in [14]. In this paper, we leverage the results from [14], [34] and incorporate the effects of EH and blockages. The characterization of HCPP models via the Laplace Functional and probability generating functionals is quite difficult to analyze and hasn't been properly done yet.…”

“…While [12] considers the deployment of relays as a network infrastructure without a wired backhaul connection, [13] explores the potential of deploying relays to design a cost effective network. It was shown in [14] that the use of relays can be a promising solution for mmWave systems to combat the blockage effects and path losses that are encountered in mmWave networks. In this regard, multiple relays can be deployed between the sources and the destination of a transmission link.…”

Abstract-We investigate the energy harvesting (EH) potential of an outdoor millimeter-wave (mmWave) network aided by wirelessly powered relays (WRs). Due to the effect of propagation characteristics, such as blockages, WRs can assist the coverage in mmWave networks. In this paper, we consider the WRs to be equipped with battery units that can store ambient RF energy from the mmWave sources. The sources and the WRs are modeled as independent homogeneous Poisson point processes (PPPs). Leveraging tools from stochastic geometry, we study the EH potential of the WRs and their coverage probability based on the amount of energy that can be harvested. To successfully receive and transmit, the batteries in the WRs have to store sufficient energy, while the received signal to interference plus noise (SINR) ratio at the destination is above a certain threshold level. We also analyze the node isolation and network connectivity probabilities for the WRs considering a bounded region. Based on this bounded region of the WRs, we then select the best WR to forward the message from sources to the destination. Furthermore, the coverage probability is also analyzed for the WRs residing both within and outside the bounded region.

Device‐to‐device (D2D) and millimeter‐wave (mmW) communications play an important role in the design of future wireless communication systems since they are mature and resource‐efficient technologies. Integrating both technologies while retaining the benefit they offer in isolation is challenging. In this article, we review the literature on mmW‐based D2D proposals to enable network applications and service extensions that span from network‐controlled use cases to opportunistic solutions for direct data exchange, caching, and relay. The survey unveils that, although a large effort has been devoted to the study of D2D with mmW, we are still far from a full analytical and experimental characterization of the system. More effort is needed in view of 5G and beyond, to consider the integration of network computing elements and to protect mmW‐based D2D against security threats
