“…Scientific works using MEC for vehicular applications are mainly focused on the theoretical and mathematical analysis of the allocation of resources to offload heavy processing tasks over a pool of computing infrastructures to boost latency and reliability [22], [23], [24], [25], [26], and save energy and costs [27]. More practical ones explore the actual limits of these architectures, studying the limits on reducing the latency by the MEC services when compared to cloud infrastructures [28], analysing the interoperability when using multi-Radio Access Technologies (RAT) to grant universal access [29], and reviewing the versatility of MEC infrastructures when using virtualization and containerization technologies to automate the management of MEC services' lifecycle [30], [31]. However, the literature mainly targets services for individual vehicles using a collective view of the data [32].…”

The reliability and availability of network connectivity, which significantly varies with mobility, is crucial in Connected, Cooperative and Automated Mobility (CCAM). Handover and roaming are the most challenging situations in terms of connectivity of cellular networks, which require switching across cells of the same cellular network or between Public Land Mobile Networks (PLMNs). This paper proposes a set of solutions for vehicular applications to mitigate the impact of mobility in service continuity, including a dual modem solution that reduces the interruption time when switching PLMNs, an adaptive bitrate mechanism for media streaming that increases reliability, a WebRTC server acting as a gateway in media streaming sessions between vehicles, and a MEC discovery and handover method. The proposed solutions have been evaluated executing an Extended Sensors application in several commercial and experimental 5G Non-Standalone (NSA) and Stand Alone (SA) setups with different Multi-access Edge Computing (MEC), edge-cloud and cloud infrastructures to host services. It can be concluded from the results obtained that 5G networks have not yet achieved the required performance for CCAM, and that practitioners need to implement solutions and workarounds, such as the ones proposed in this work, to mitigate the issues. As lessons learnt from the deployment and experimentation, this paper also overviews a detailed set of problems and the proposed solutions that CCAM industry and cellular network stakeholders need to consider.INDEX TERMS 5G, MEC, CCAM, inter-PLMN handover, vehicular communications, testing.

“…The two competing technologies are, as of yet, not interoperable at radio access level. It raises the problem that vehicles using different radio technologies will not be able to communicate directly [6]. This has important disadvantages, as the full benefits of V2X will only be realized if an interoperable system, working across all Original Equipment Manufacturers (OEMs) and borders, is established [7].…”

Cooperative intelligent transport systems (C‐ITS) deployments for vehicle‐to‐infrastructure communication require substantial investments from European Member States in road‐side units (RSUs) and in central traffic management systems. The promise of numerous societal benefits should justify these public investments. However, C‐ITS uptake in passenger cars, and thus the subsequent societal benefits, are highly uncertain. Therefore, here, a case study of Flanders is presented in which real option analysis) is used to help road authorities assess the RSU investment opportunity. The framework combines a detailed cost and benefit model and includes managerial options for the road authority. This technique aims to incorporate the value of the flexibility that is available during the deployment to reduce risk exposure, and as such more accurately appraise the investment. C‐ITS uptake in passenger cars was modelled as the major source of uncertainty, as it is the primary driver of societal benefits. While a static RSU investment analysis for Flanders, Belgium, was found to be negative, embedding the option to defer the investment decision to further study C‐ITS uptake results in a positive average net present value. The results are useful for any road authority aspiring to roll out C‐ITS road‐side infrastructure.

The Internet of Vehicles is widely applied in the context of connected systems nowadays. A vehicular network, a structure that provides vehicle-to-everything communication, can solve many issues in IoV. However, it deals with connectivity restrictions such as volatility, latency, bandwidth, and interoperability. To deal with these issues, applications can use lightweight IoT protocols such as the Constrained Application Protocol (CoAP). This paper presents a practical use case implemented using the CoAP protocol, considering a Multi-access Edge Computing (MEC) scenario, which runs cloud services at the network's edge and performs specific interoperable tasks. The evaluated scenario considers a V2X Streaming Service application that uses the V2X Information Service, an API to facilitate the interoperability between V2X communications and external applications. The study concludes that CoAP can fulfill the scenario's connectivity requirements and facilitate interoperability between IoT services.
