“…Relevant examples of solutions appeared in the literature, targeting the support of safety applications through the aforementioned types of messages, include [150] where V2V periodic messages allow for collective perception sharing based on Release-14 LTE PC5 mode 4, and [151] which envisions mobile base stations deployed in UAV to improve the connectivity offered to vehicles by terrestrial base stations. The use of V2V event-driven messages, combined with CAM transmissions, has been instead leveraged in [152] to implement a cooperative lane merging application using the LTE PC5 mode 4 technology. Interestingly, [153] and [154] have highlighted the limitations of the configuration of PC5 mode 4 interfaces in Release-14 LTE, and, especially, of the autonomous sidelink resource allocation algorithm to transmit V2V event-driven messages -an issue that has then been overcome in Release-16 NR PC5 mode 2 [155].…”

She currently serves as the Vice Rector for Alumni and Career Orientation at Politecnico di Torino. She is an IEEE Fellow. Her research interests include the design of wireless network architectures, the defi nition of protocols and algorithms for mobile networks and applications, and the creation of theoretical models for the study and the performance evaluation of wireless systems. Her research is indeed a combination of system design and network-theory, aiming to design algorithms and methods that solve real problems, starting with actual data and scenarios. As far as application domains are concerned, she has been focusing on energy efficiency of wireless systems, connected cars, mobility services, service virtualization, and smart healthcare.After studying Latin and ancient Greek in high school, she decided for a change and enrolled in the Electrical Engineering B.S. and M.Sc. Program at the University of Florence, Italy. She did her Master thesis on security in wireless networks under the supervision of Prof. Aura Ganz, at the University of Massachusetts at Amherst, MA, and received her Ph.D. from Politecnico di Torino in 2000. During her Ph.D., she was a visiting scholar at the University of California at San Diego (UCSD), CA, working with Prof. Ramesh Rao. She was then a visiting researcher at UCSD in 2000-2003. These experiences gave her the unique opportunity to explore highly innovative aspects in energy efficiency of wireless communication devices as well as in local and personal wireless networks. In particular, she developed pioneering, highly inter-disciplinary work on the modeling of battery behavior in mobile devices and the designing of algorithms and protocols aiming at establishing the optimal tradeoff between energy saving and the level of user's quality of service. At UCSD she had the opportunity to also work with Prof. John Proakis and to participate in research projects involving large companies. Afterwards, she started investigating the coexistence between diff erent wireless technologies, and cooperation in distributed wireless networks through the lens of game theory.

“…Most of the research contributions reported in the recent literature address the previous problems from two rather decorrelated perspectives. On the one hand, some studies focus on the performance assessment of radio technologies on their own, for instance C-V2X sidelink based Vehicle-to-Vehicle (V2V) communications, most often at link level and regardless of any concrete application (e.g., [2]- [4]), or V2I communications with respect to Road Side Units (RSUs) (e.g., [5]) under various road infrastructure deployment assumptions (e.g., [6]). On the other hand, a second major research direction concerns the higher-level orchestration of networks, services and/or of MEC resources [7]- [9].…”

By means of system-level simulations, we analyze in this paper the performance of Vehicle-to-Network (V2N) connectivity based on the 5th Generation -New Radio (5G-NR) as a support to Cooperative, Connected and Automated Mobility (CCAM), in light of both network and Multi-access Edge Computing (MEC) deployments. Focusing on a canonical centralized Cooperative Lane Change (CLC) use case that involves three vehicles in a cross-border highway environment, we assess the link reliability and the End-to-End (E2E) latency of all the messages involved in the CLC negotiation phase (from/to interconnected MECs hosting the centralized maneuvering application), while assuming different deployment configurations and the coexistence with a second demanding vehicular service running over the same radio resources. On this occasion, we illustrate possible benefits from Bandwidth Partitioning (BWP) on Uplink (UL) latency, as well as from an hypothetically tight cooperation between Mobile Network Operators (MNOs) on reliability and continuity, leveraging low-latency inter-MEC transactions and seamless cross-border handover capabilities.

“…Regarding our proposal, future studies can explore different traffic situations such as overtaking and different types of structures in a road network. And also consider using sections of real cities and even performing a simulator calibration for that particular region with real data as performed by Poli et al (2021). Investigating negotiation algorithms in more complex and realistic scenarios would be a major advancement for the field of ITS.…”

“…The negotiations might become invalid if they take too long to complete. According to Poli et al (2021), the longer negotiation time results in a higher rejection rate of proposals. In such cases, it is likely that the trajectory time interval should be longer than the 10 seconds we set in our experiments.…”

“…The authors present two scenarios, a highway lane-reduction scenario and an urban intersection-crossing scenario, to demonstrate the effectiveness of their approach. Poli et al (2021) proposed a negotiation based on Cooperative Lane Merging called Cellular-Vehicle-to-Everything, which is sidelink connectivity for Cooperative Lane Merging services in a specific cross-border highway context. The negotiation protocol involves three vehicles: the initiator, the second vehicle in charge of creating the gap, and the merging vehicle.…”

O crescimento populacional e a rápida expansão urbana no último século geraram uma aglomeração metropolitana que causou inúmeros impactos sociais e econômicos. A alta demanda por mobilidade resultou em um número crescente de veículos nas estradas, levando a tempos de viagem mais longos, o que tem causado congestionamentos, aumento dos índices de acidentes e aumento da poluição. Os Sistemas de Transporte Inteligente (ITS) têm o potencial de revolucionar o transporte e a mobilidade urbana ao reduzir acidentes de trânsito, mitigar congestionamentos e engarrafamentos.A comunicação entre veículos permite negociação e cooperação que podem ser usadas em vários contextos, como cruzamentos, junções de faixa e mudança de faixa. A resolução de conflitos entre veículos é uma tarefa desafiadora devido à maior densidade de veículos e espaço de manobra limitado, muitas vezes apenas mudanças de velocidade é permitido. Um número significativo de estudos focam em soluções centralizadas que possuem uma forte dependência da infraestrutura. Além disso, há poucas pesquisas sobre métodos de negociação descentralizada que levem em consideração sistemas multiobjetivos onde cada veículo tem sua própria função de custo privada e também existem poucos trabalhos focados em soluções generalizadas que abordam diferentes cenários dinâmicos com fluxo de tráfego usando a mesma abordagem.Esta tese propõe um método para resolução de conflitos entre veículos que possuem a capacidade de se comunicar de forma descentralizada e que pode ser utilizado em múltiplos cenários dinâmicos, tais como: cruzamentos, junções de faixa e mudanças de faixa. Também consideramos veículos com diferentes características, dimensões e funções de custo privadas. A abordagem proposta visa melhorar o fluxo de veículos e reduzir o tempo de viagem que pode ser traduzido na redução de emissão de poluentes.Para avaliar a proposta, utilizamos uma ferramenta de simulação para criar diversos cenários de teste e comparamos os resultados com métodos existentes utilizando métricas comumente utilizadas na literatura. Além disso, também foi necessário adaptar a ferramenta de simulação para incluir recursos como cálculo de trajetória, detecção de colisão e gerenciamento de veículos em relação ao processo de tomada de decisão.Em todos os cenários, melhorias significativas foram alcançadas em termos de fluxo de veículos, resultando em diminuição do tempo de viagem e aumento da velocidade média em relação aos benchmarks utilizados.
