Slicing on the Road: Enabling the Automotive Vertical through 5G Network Softwarization

Abstract

The demanding requirements of Vehicle-to-Everything (V2X) applications, such as ultra-low latency, high-bandwidth, highly-reliable communication, intensive computation and near-real time data processing, raise outstanding challenges and opportunities for fifth generation (5G) systems. By allowing an operator to flexibly provide dedicated logical networks with (virtualized) functionalities over a common physical infrastructure, network slicing candidates itself as a prominent solution to support V2X over upcoming programmable and softwarized 5G systems in a business-agile manner. In this paper, a network slicing framework is proposed along with relevant building blocks and mechanisms to support V2X applications by flexibly orchestrating multi-access and edge-dominated 5G network infrastructures, especially with reference to roaming scenarios. Proof of concept experiments using the Mininet emulator showcase the viability and potential benefits of the proposed framework for cooperative driving use cases.

Software-Defined Vehicular Cloud Networks: Architecture, Applications and Virtual Machine Migration

“…The SDN concept mitigated the system overheads cost by proposing two-side matching theory that solves the matching problem among the pseudonym pools. In the works by Campolo et al [52], V2X network slices are implemented through the use of softwarization technologies such as SDN, NFV, and MEC. The aim of the V2X network slice enables the cooperative driving services under intra-and inter-operator mobility.…”

“…Mininet-WiFi is an extension of the Mininet [59] emulator to simulate a mobile wireless node. SUMO is used to inject traffic mobility to allow Mininet-WiFi to evaluate SDVN architecture [45,52]. However, the Mininet-WiFi platform lacks the ability to apply VM migration technologies.…”

“…A vehicular edge/fog computing to support the control layer over SDVN for content delivery is discussed in [9,[45][46][47][48]. Al-Badarneh et al [45] and Campolo et al [52] evaluated slicing road framework in 5G network softwarization for content delivery using Mininet-WiFi emulator. The content delivery is transmitted through V2X communication.…”

Scalability and Performance Analysis in 5G Core Network Slicing

“…Campolo et al [9] presented a network slicing architecture to support V2X applications. This architecture introduces a service layer in which the core network comprises several NFs, such as AMF, AUSF, and Unified Data Modeling (UDM).…”

“…Also, this approach does not measure some essential performance indices, such as processor utilization and throughput. In the 5GNSL literature, the approaches proposed by Trivisonno et al [8], Campolo et al [9], and Schneider et al [10] use different techniques, such as simulations, emulations, and Queuing Petri Nets, to evaluate performance. However, these approaches do not analyze the scalability of 5GNSLs.…”
