“…The results are exact for onehop scenarios and approximated, yet accurate enough, for multi-hop scenarios, as we shall show, which makes it a useful numerical tool for a quick evaluation of new proposals and mechanism variations, as we also illustrate with examples. Moreover, it is specifically aimed at the case in which vehicles select their contention slots in different ways, unlike other available models [73,100,118,124].…”

“…However, unlike our work, formal descriptions and analytical models for quick numerical evaluation of the different proposals are rarely provided. In this latter regard, different analytical models can be found in [73,100,118,124], but they cannot be applied to the specific case in which each vehicle selects its contention time slot in a different way.…”

Vehicular Ad-hoc Networks (VANETs) have been receiving a growing research interest from both the Academia and the Industry, due to the potential benefits provided by the broad range of applications that might be derived from their use.VANETs use wireless communications in which the information can be transmitted among vehicles (V2V) or among vehicles and road infrastructure (V2I). This technology paves the way for future Intelligent Transportation Systems (ITS), which integrate advanced information, communication and control technologies to bring major improvements to the existing transportation network, like vehicle traffic control or driver information systems.One of the most promising benefits of vehicular communications is the improvement of traffic safety. Cooperative Collision Avoidance (CCA) applications are a new emerging means of reducing the number of accidents on the road by providing cars with collaborative communication capabilities, thus allowing them to better react against possible accident risks. However, to design and implement such applications, a deep understanding of the vehicle collision process is needed. The influence of different driving parameters on the collision event must be assessed at an early design stage to develop applications that can timely adapt vehicle dynamics to avoid or at least mitigate the danger. In this context, this thesis presents and evaluates a novel stochastic model that enables the computation of the average number of collisions that occur in a platoon of vehicles driving in a single-lane road. At the same time, the model allows to study the effect of different driving parameters (inter-vehicle distance, driver reaction time, braking deceleration, etc.) on the collision process.Next, we focus on the efficiency and reliability of emergency messages propagation, which should reach all the vehicles within a certain area in a limited time. The delivery of these geographically-addressed messages is performed by the GeoNetworking protocol, which uses a forwarding mechanism to route packets through intermediate nodes until reaching the destination. We assess here how cross-layer techniques, allowing the exchange of information between the different communication layers, can help to improve the operation of GeoNetworking by optimizing the forwarding algorithm in use. We finally provide a survey and comparative evaluation of the most relevant proposals in the context of vehicular environments, focusing on the particular cases involving the MAC (Medium Access Control) and network layers.

“…Given several relevant input parameters, they captured the performance mainly in terms of the probability distribution of the E2E and per-hop delay. Another work by the same authors [151] is dedicated to analytical modeling of geographical multi-hop broadcast in VANETs as a means of evaluating its performance. Besides the measures discussed in their previous work, they investigated the required number of hops to cover a given one-dimensional dissemination distance.…”

With all their affection and support, making me feel strong and capable during all stages of my life. They always gave me the freedom and all I needed to follow my dreams and make them happen. Simply, I cannot thank them enough for all they did for me. My only sister beloved Mozhgan, with a heart of gold, cheering me up all the time. She has been always supportive and caring with precious advices. My brother in-law Hamed, who have always been supportive and encouraging during these years. My sweet nephews Anis and Tanin, the bright stars bringing so much positive energy and joy into my life.And my love Morteza who is my best friend. We have been passing through a long journey, with strength and tenderness. He has always been there for me. He is reassuring and makes me feel so strong by his persistent support and provident mind.xiii voor het verbeteren van ITS-toepassingen maar ook dienen als startpunt voor verder onderzoek. Bibliography 146Acronyms 160List of Publications 165 the following outline. Section 1.1 presents a brief introduction to vehicular networking, ITS and data forwarding in vehicular networks. The objective of this thesis and the corresponding research questions are introduced in Section 1.2, followed by our research contributions and thesis structure in Sections 1.3 and 1.4, respectively.Ensuring reliability of data dissemination is of crucial importance for many ITS applications, in particular for the ones demanding a safety action upon reception of such data. By reliability we mean integral data delivery to the intended receivers within reasonable time.
