Preface

Nowadays, network simulation has become more affordable than real-world experiments and the least-expensive mean for the evaluation of networking propositions for Intelligent Transportation Systems. This requires that, for purposes of accuracy, simulation software adapts to the simulated field. Which, for the case of ITS, results in integration of realistic mobility, wireless communication environments, and protocol mechanisms that are as precise as possible.

However, every simulation user should be aware of the fact that simulation only represents the functioning of the real world in a limited way.

In this book, we show how simulation can be used in several domains of ITS, ranging from vehicular to railway and aircraft communication networks, with appropriate examples. In the 10 chapters of this book, several levels of the communication models and the technologies of ITS communication are addressed. This ranges from channel modeling to traffic generation, including access layer and routing.

In Chapter 1, Robert Proztmann et al. address the scalability of vehicular communication technologies on the basis of IEEE802.11p when mixed with LTE technology. They present a multi-aspect simulation environment called VSimRTI, a comprehensive framework that connects various simulation tools together to cover all aspects needed for a proper evaluation of new cooperative mobility solutions for ITS.

In Chapter 2, Christian Pinedo et al. address the challenges associated with the interaction of the Internet of Things (IoT) and the ITS domain. They aim to provide guidelines on modeling these smart, low-cost, near-field wireless objects and on how to integrate their behavior in traditional network Discrete Event Simulation (DES) tools.

In Chapter 3, Fabien Garcia et al. analyze the current traffic regulations in different airspaces. They lay out the constraints in aircraft movement as well as the different types of mobility models and their respective merits. They finally present traffic traces’ extraction, enhancement and filtering, leading to new developments on cooperative trajectory studies as a new trend.

In Chapter 4, Christophe Guerber et al. deal with data exchanges between on-board and ground systems. They explain how simulation can be a solution to assess the performances of aeronautical communication architectures and protocols through the examples of communication technologies such as VHF Data Link (VDL) and Aeronautical Mobile-Satellite Service (AMSS).

In Chapter 5, Patrick Sondi et al. propose, in the context of the European Rail Traffic Management System (ERTMS), a virtual laboratory based on co-simulation. It relies on two existing tools: an ERTMS simulator implementing the functional subsystem (ETCS) and an OPNET simulator that enables the modeling of the whole telecommunication subsystem, namely the GSM-R (Global System for Mobile Communications  Railways). They also address the evolution from co-simulation to multi-modeling in order to directly connect the models and avoid the problems related to heterogeneity of simulators.

In Chapter 6, Herve Boeglen et al. show the effects encountered when WiFi frames are transmitted over the air. They provide a channel simulation solution, which is a trade-off between computing time and realism. The source code for ns-3 of this solution is provided in an appendix.

In Chapter 7, Justinian Rosca et al. present a platform that flexibly integrates a traffic simulator with a communication simulator, thus providing an ideal platform for co-simulating transportation system applications. The communication models can be tuned on the basis of real-world measurements in scenarios such as urban, residential and highway traffic.

In Chapter 8, Marco Gramaglia et al. focus on the representation of road traffic for the simulation of highway vehicular networks based on V2V communication technologies and present an original, fine-tuned, measurement-based mobility model.

In Chapter 9, Sebastien Bindel et al. explore the Link Quality Estimators (LQE) in the context of VANET. They propose a metric (F-ETX) that automatically adapts to the link quality and provides a trade-off between the dynamicity and accuracy of Link Quality assessment.

In Chapter 10, Nader Mbarek et al. show how to adapt the Autonomic Computing paradigm to ITS and in particular to Vehicular Ad hoc Networks (VANETs) in order to enhance the performance of communications in such changing environments. The design of a QoS-based broadcasting protocol is presented as a usage case.

We hope that this multi-purpose book will help the reader to move a step forward in their understanding and/or current work in the domain of network simulation for Intelligent Transportation Systems.
