“…To model the transmission of signals for CRLB estimation and technologies comparison, physical layer performance should be addressed. In this regard, compared with V2V channels, a research gap is mentioned to support V2I communication coverage prediction and interference analysis [ 39 , 40 , 41 ]. The study in [ 42 ] compares IEEE 802.11p and LTE-V technologies considering vehicular communication in an urban non-line of sight (NLOS) scenario.…”

The future of transportation systems is going towards autonomous and assisted driving, aiming to reach full automation. There is huge focus on communication technologies expected to offer vehicular application services, of which most are location-based services. This paper provides a study on localization accuracy limits using vehicle-to-infrastructure communication channels provided by IEEE 802.11p and LTE-V, considering two different vehicular network designs. Real data measurements obtained on our highway testbed are used to model and simulate propagation channels, the position of base stations, and the route followed by the vehicle. Cramer–Rao lower bound, geometric dilution of precision, and least square error for time difference of arrival localization technique are investigated. Based on our analyses and findings, LTE-V outperforms IEEE 802.11p. However, it is apparent that providing larger signal bandwidth dedicated to localization, with network sites positioned at both sides of the highway, and considering the geometry between vehicle and network sites, improve vehicle localization accuracy.

VANET broadcasting algorithm plays an important role in ensuring the reliability and speed of information interaction between vehicles. Recently, the multi-hop broadcast has become a promising direction. In this paper, we propose a multi-hop broadcasting algorithm called delay-constraint broadcast combined with resource reservation mechanism (DBCRRM) which can increase the packet delivery ratio (PDR) effectively. The proposed broadcasting algorithm can make use of the distance between the source node and receiving nodes to select the forwarding node and uses the resource reservation mechanism (RRM) to select the resource of timeslot and frequency. Meanwhile, the algorithm can ensure the delay in the permissible range. Due to the difficulty of the field test in VANET broadcasting algorithms, most VANET broadcasting algorithms are only evaluated by simulation but lack the results of field tests. To make up the deficiency, we design a field test platform for broadcasting algorithms in VANET, and practically test the delay-constraint broadcast (DB) and DBCRRM. Compared to the test results of two-hop broadcast and the one-hop broadcast, the DBCRRM and DB show the superiority and practicability.INDEX TERMS Vehicular ad-hoc networks, delay-constraint broadcast combined with resource reservation mechanism, test platform, OpenWrt boards.

We investigate propagation characteristics for wireless channels, applicable to Integrated Access and Backhaul (IAB) and relay-based networks with lamppost-height nodes at 5.5 GHz. We compare our empirical results with a variety of models that have been proposed for system simulation. Our work is based on an extensive measurement campaign in an urban environment, where we simultaneously measured base-relay, relay-mobile and base-mobile links. This simultaneity allows us to conclude that low-height relay nodes offer a minor path-loss advantage over the base-user link. Moreover, within the range of relay heights that we measured of 2.8 and 4.7 m, we observed no significant gain associated with choosing the higher relay placement. Our results however also show that the base-relay link is quite stable over time and thus will lend itself to multi-antenna techniques requiring a small overhead in channel state information feedback. Our results add to the empirical data that the standards models are based on, providing path-loss results obtained simultaneously for all links of an urban relay-based system.INDEX TERMS Channel models, integrated access and backhaul, 5G IAB, path loss, propagation, relay networks.
