Vehicle-to-everything (V2X) communication is the next innovative technology to transform the automotive industry. It implements the power of Internet of things (IoTs) connectivity and processing to improve the efficiency, performance, and safety of future vehicles. V2X enables vehicles to have a high awareness of the surrounding environmental factors, infrastructures, and other vehicles through the advanced sensing and communication technologies in place. Current communication platforms in place are not able to fully support the transmission of high priority safety critical data required to provide these services. Individually, the two main V2X architectures (DSRC and C-V2X) have limitations which inhibit them from fully supporting the V2X platform. As such, this chapter proposes the integration of 5G technology, which supports all types of communication technologies through the integration of reconfigurable devices and offers higher data rates and bandwidths than any preceding platform. The architecture proposed in the chapter is composed of three layers: DSR V2X for direct short-range communication; cellular V2X layer which will combine 5G cellular platform to provide backup communication when DSR V2X layer fails and multimedia capabilities; and satellite (SAT)-V2X which provides extra backhaul connectivity when both DSR and cellular V2X is unavailable. The system design, modeling, and simulation results yield a more reliable and sustainable V2X capacity for critical real-time vehicular communication applications.

This paper revisits the impact of channel phase in multibeam multicast satellite precoding. First, we analyze the unicast case showing that the phase components relative to the different slant paths to each user do not affect the precoding performance. Then, we indicate that for the multicast transmission, the mentioned phase effect may have impact depending on the employed clustering technique. Finally, we propose an alternative clustering solution based on normalizing out the phase components relative to the different slant paths. According to our simulation results, this novel clustering technique provides robustness to these phase components and also behaves better than previously reported clustering schemes.

The High Data Rate Architecture (HiDRA) project is implementing a High-rate Delay Tolerant Networking (HDTN) capability that can support Low Earth Orbit (LEO) applications and environments. The present state of the effort, future work, and other elements of the work to date are described in this paper. This implementation is intended to support applications that run at 1+ Gbps, per the requirements of modern optical and high-frequency RF links. Uniquely, this implementation is also tuned to support relay and data trunking applications, which might require support for large numbers of small bundles per second. The design for this platform is based entirely on commercial-off-the-shelf (COTS) components, and possesses buffering capabilities in the 5 TB range. This document takes results from previous individual tests and integrates them to demonstrate results in the presence of a coherent use-case: consider a network aboard the ISS which intends to utilize an upcoming optical communications capability. For this use-case, orbital analysis software is used to analyze orbital dynamics, from which a list of access times are generated that might take in to account weather, schedule competition, etc. A variant of Contact Graph Routing (CGR) is applied to these windows to determine an optimal schedule. This schedule is then loaded into the HDTN prototype and, in conjunction with various measurement tools, a complete end-to-end analysis of HDTN’s performance is conducted. Various bottlenecks (including storage) are identified: these bottlenecks are expected to help us focus our future work on the elements of the system that are most likely to present issues moving forward. Finally, we discuss possible paths for evolution beyond the present rates supported by the system, including (but not limited to) hardware acceleration.
