“…Numerical results also show that largescale antenna arrays are required for satisfactory coverage in mm-wave networks. To further enhance the connectivity and session continuity, multi-connectivity strategies were developed to leverage multiple simultaneous small cell connections in ultradense urban deployments of mmWave networks in [246]. The benefits of multi-connectivity strategies were investigated by taking into account: (i) the intricacies of mmWave radio propagation in realistic urban environments; (ii) the dynamic mmWave link blockage due to human mobility; and (iii) the multi-connectivity network behavior to preserve session continuity.…”

Abstract-Millimeter wave (mmWave) communications have recently attracted large research interest, since the huge available bandwidth can potentially lead to rates of multiple Gbps (gigabit per second) per user. Though mmWave can be readily used in stationary scenarios such as indoor hotspots or backhaul, it is challenging to use mmWave in mobile networks, where the transmitting/receiving nodes may be moving, channels may have a complicated structure, and the coordination among multiple nodes is difficult. To fully exploit the high potential rates of mmWave in mobile networks, lots of technical problems must be addressed. This paper presents a comprehensive survey of mmWave communications for future mobile networks (5G and beyond). We first summarize the recent channel measurement campaigns and modeling results. Then, we discuss in detail recent progresses in multiple input multiple output (MIMO) transceiver design for mmWave communications. After that, we provide an overview of the solution for multiple access and backhauling, followed by analysis of coverage and connectivity. Finally, the progresses in the standardization and deployment of mmWave for mobile networks are discussed.

“…The distance between any two vehicles on any lane is random. The distributions of D and W are the same and follow an exponential distribution with parameter l. This scenario is typical for traffic jams and urban areas [37]. For the sake of simplicity, the buildings and any other obstacles that may potentially appear in the scenario are not modeled.…”

Abstract-Communications systems operating in the millimeter-wave (mmWave) and terahertz band have been recently suggested to enable high data-rate vehicle-tovehicle communications in 5G and beyond wireless networks. However, massive deployment of such systems may lead to significant interference, affecting the performance of information transmission. While the multipath interference caused by the signal reflections from the road has been extensively discussed in literature, the interference caused by the vehicles on the side lanes has been insufficiently studied so far. In this paper, using a combination of measurement, simulation, and analytical methods we comprehensively characterize the interference from the side lanes in two typical deployments including highway and urban road environments for millimeter-wave and low terahertz bands. Both the multipath interference and direct interference from the transmitting vehicles on the side lanes is taken into account. As a result of our study, we reveal that: i) the interference from the side lanes can be well approximated using two-dimensional stochastic models without any significant loss of accuracy; and ii) even when highly directional antennas are used there are special spatial configurations, where the interference may greatly affect the performance of the communication systems. We lately apply the developed models to estimate the signal-to-interference ratio and link capacity of mmWave/THz band V2V communications.

Contemporary urban environments are in prompt need of means for intelligent decision-making, where a crucial role belongs to smart video surveillance systems. While existing deployments of stationary monitoring cameras already deliver notable societal benefits, the proposed concept of massive video surveillance over connected vehicles that we contribute in this paper may further augment these important capabilities. We therefore introduce the envisioned system concept, discuss its implementation, outline the high-level architecture, and identify major data flows, while also offering insights into the corresponding design and deployment aspects. Our conducted case study confirms the potential of the described crowd sourced vehicular system to effectively complement and eventually surpass even the best of today's static video surveillance setups. We expect that our proposal will become of value and integrate seamlessly into the future Internet-of-Things landscape, thus enabling a plethora of advanced urban applications.
