Wireless Communication Technologies for Safe Cooperative Cyber Physical Systems

Cooperative Cyber-Physical Systems (Co-CPSs) can be enabled using wireless communication technologies, which in principle should address reliability and safety challenges. Safety for Co-CPS enabled by wireless communication technologies is a crucial aspect and requires new dedicated design approaches. In this paper, we provide an overview of five Co-CPS use cases, as introduced in our SafeCOP EU project, and analyze their safety design requirements. Next, we provide a comprehensive analysis of the main existing wireless communication technologies giving details about the protocols developed within particular standardization bodies. We also investigate to what extent they address the non-functional requirements in terms of safety, security and real time, in the different application domains of each use case. Finally, we discuss general recommendations about the use of different wireless communication technologies showing their potentials in the selected real-world use cases. The discussion is provided under consideration in the 5G standardization process within 3GPP, whose current efforts are inline to current gaps in wireless communications protocols for Co-CPSs including many future use casesinfo:eu-repo/semantics/publishedVersio

A simulation approach for increased safety in advanced C-ITS scenarios

Com os recentes desenvolvimentos em diferentes áreas de conhecimento, como redes de comunicação sem fio e sensores, bem como a evolução recente em vários tópicos na área da Computação, os Sistemas Inteligentes e Cooperativos de Transporte (CITSs) tornaram-se um tema muito importante, e espera-se que comecem a ser cada vez mais implementados num futuro próximo. Nesta tese, é feita uma análise sobre estes sistemas e diferentes possiveis cenários focando no cenário de Platooning, assim como sobre comunicações Veículo-a-Tudo (V2X) com foco no ETSI ITS-G5, o standard europeu mais amplamente aceite na indústria automóvel para este tipo de comunicações. O desenvolvimento de duas ferramentas de co-simulação para análise de cenários C-ITS usando comunicações veículo para veículo (V2V), foi feito no contexto desta tese. COPADRIVe é uma ferramenta de co-simulação que junta um simulador de rede e um simulador robótico. A outra ferramenta de co-simulação, é uma ferramenta hardware-in-the-loop que úne um simulador robótico com comunicações feitas através de hardware real, On-Board units (OBUs). Ambas as ferramentas foram desenvolvidas e usadas como forma de análise e teste de situações de Platooning e componentes de software para implementação neste tipo de cenários. Este desenvolvimento teve origem na necessidade de existência deste tipo de ferramentas para suporte dos desenvolvimentos feitos no contexto dos Projetos europeus de I&D SafeCOP e ENABLE-S3, onde o CISTER participava ativamente.With the developments in different areas like Wireless Communication Networks and sensors, as well as, the recent evolution on various topics on Computing, Cooperative Intelligent Transportation Systems(C-ITSs) became a hot topic for research, and are expected to be increasingly deployed in the future. From the different possible scenarios, in this thesis, we focus in analyzing Cooperative Platooning and particularly, in enabling a set of simulation tools capable of encompassing the supporting Vehicle-to-Everything(V2X) communications guaranteed by the ETSI ITS-G5, the most widely accepted European standard on the automotive industry for these kind of communications. Therefore this thesis presents the development of two co-simulation tools for analysis of C-ITS scenarios using Vehicle-to-Vehicle(V2V) communications. First, COPADRIVe is a co-simulation tool joining together a network simulator and a robotic simulator. The other co-simulation tool, uses a a hardware-in-theloop approach one bridging a robotic simulator with real communications via OnBoard-Units (OBUs). Both tools were developed and used as the means to test and analyze Platooning scenarios and software components relevant in such applications, importantly. These tools’ were developed in line with the R&D European Projects SafeCOP and ENABLE-S3, where CISTER was and active participant
