Socially Inspired Relaying and Proactive Mode Selection in mmWave Vehicular Communications
IEEE Internet of Things Journal. 2019. Vol. 6. No. 3. P. 5172–5183.
As the Internet of Vehicles matures and acquires its social flavor, novel wireless connectivity enablers are being demanded for reliable data transfer in high-rate applications. The recently ratified New Radio communications technology operates in millimeter-wave (mmWave) spectrum bands and offers sufficient capacity for bandwidth-hungry services. However, seamless operation over mmWave is difficult to maintain on the move, since such extremely high frequency radio links are susceptible to unexpected blockage by various obstacles, including vehicle bodies. As a result, proactive mode selection, that is, migration from infrastructure- to vehicle-based connections and back, is becoming vital to avoid blockage situations. Fortunately, the very social structure of interactions between the neighboring smart cars and their passengers may be leveraged to improve session continuity by relaying data via proximate vehicles. This paper conceptualizes the socially inspired relaying scenarios, conducts underlying mathematical analysis, continues with a detailed 3-D modeling to facilitate proactive mode selection, and concludes by discussing a practical prototype of a vehicular mmWave platform.

The fifth and sixth (5G/6G) generations of cellular systems utilizing the millimeter wave (mmWave, 30–100 GHz) and sub-terahertz (sub-THz, 100–200 GHz) bands are known to be affected by blockage and micromobility phenomena. These effects make the channel highly time-varying in terms of the number of packets that can be serviced in a single scheduling unit. ...

Emerging eXtended Reality (XR) applications impose strict requirements on throughput, delay, and reliability, which limits the capacity of 5G systems operating only in one band, i.e., either a sub-6-GHz band or a mmWave one. To address this problem, the letter considers a scenario with a mixture of XR and broadband traffic and explores how to ...

The introduction of integrated access and backhaul (IAB) technology in beyond 5G systems will result in multiple wireless backhaul links between the user equipment (UE) and the base station (BS). This configuration motivates the research into traffic at the packet level to evaluate the quality of service (QoS) provided to users. At the same time, ...

Today's internet is almost wholly dependent on data originated by limited accuracy, time, and attention humans. If computers can access to accurate information about things, they would be able to count, track, and predict everything. If everything is connected to internet, the gap between our physical world and cyberspace will be reduced. Research activities are ...

Emerging wireless systems target to provide multi-Gbps data rates for each user, which can be achieved by utilizing ultra-wide channels available at mmWave, terahertz, and lightwave frequencies. In contrast to the traditional spectrum below 6 GHz, these high-frequency bands raise many issues, complicating their usage. For example, because of high signal attenuation and blockage by ...

Augmented and Virtual Reality (AR/VR) is often called a "killer" application of 5G systems because it imposes very strict Quality of Service (QoS) requirements related to throughput, latency, and reliability. A high-resolution AR/VR flow requires a bandwidth of dozens of MHz. Since the existing low-frequency bands (i.e., below 6 GHz) have limited bandwidth and are ...

To alleviate the impact of outages caused by dynamic blockage of propagation paths in millimeter wave (mmWave) systems, 3GPP has proposed multi-connectivity operation, where user equipment (UE) maintains simultaneous links to both sub-6 GHz and mmWave BSs. We address one of the most challenging prospective deployments - multi-lane street deployment with intra- and inter-RAT multi-connectivity. ...

Today, the rapid adoption of mobile social networking is changing how and where humans communicate. As a result, in recent years we have been increasingly moving from physical (e.g., face-to-face) to virtual interaction. However, there is also a new emerging category of social applications that take advantage of both worlds, that is, using virtual interaction ...
