Abstract
In this paper we present a special simulation environment, used to analyze the effects of a real-time vehicle-to-vehicle warning-message distribution application on road traffic. For the realization of this environment, a coupling concept for coupling a traffic and a network simulator has been developed and implemented. Besides the simulation environment and its realization we'II present simulation results. ...

Abstract
One emerging, new type of ad-hoc network is the vehicular ad-hoc network (VANET), in which vehicles constitute the mobile nodes in the network. Due to the prohibitive cost of deploying and implementing such a system in real world, most research in VANET relies on simulations for evaluation. A key component for VANET simulations is a realistic vehicular mobility model that ensures conclusions drawn from simulation experiments will carry through to real deployments. In this work, we introduce a tool MOVE that ...

Abstract
Without realistic modeling of node mobility, simulation evaluation of performance of mobile ad hoc networks may not correlate well with performance in a real deployment. In this work, we present a new, realistic model of node motion based on the movement of vehicles on real street maps. Our model can be used with the ns-2 network simulator. We compare our model with the Random Waypoint mobility model, the most widely used mobility model. Results show that, in many ways, the Random ...

Abstract
This paper investigates the feasibility of a self-organizing, completely distributed traffic information system based upon vehicle-to-vehicle communication technologies. Unlike centralized traffic information systems, the proposed system does not need public infrastructure investment as a prerequisite for implementation. Due to the complexity of the proposed system, simulation is selected as the primary approach in the feasibility studies. A simulation framework is built based on an existing microscopic traffic simulation model for the simulation studies. The critical questions for building the proposed market-driven ...

Abstract
Mobility modeling is a critical step in the design of mobile self-organizing networks. With the emergence of small-scale and short-range wireless communication devices, the communication sphere shrinks (radio range or sensing range), which leads to an increase in the need for fine-grained representations of mobility. In fact, mobility models must scale accordingly to the application and reflect real scenarios in which wireless devices are deployed. Currently, self-organizing networks are evaluated using mobility models that do not represent the precise motion of ...

Abstract
Most VANET simulators do not allow for feedback between the vehicle mobility model and the network simulator. This limits the realistic simulation of safety and traffic information applications that might cause drivers to change their routes. To address this issue, we developed extensions to the SWANS wireless network simulator. Our SWANS modules, which we collectively call ASH (Application-aware SWANS with Highway mobility), make several contributions. ASH allows for the needed two-way communication between the mobility model and the networking model. To ...

Abstract
Mobility is the distinguishing feature of vehicular networks, affecting the evolution of network connectivity over space and time in a unique way. Connectivity dynamics, in turn, determine the performance of networking protocols, when they are employed in vehicle-based, large-scale communication systems. Thus, a key question in vehicular networking is: which effects does nodes mobility generate on the topology of a network built over vehicles? Surprisingly, such a question has been quite overlooked by the networking research community. In this paper, we ...

Abstract
Vehicular traffic is a classical example of a multi-agent system in which autonomous drivers operate in a shared environment. The article provides an overview of the state-of-the-art in microscopic traffic modeling and the implications for simulation techniques. We focus on the short-time dynamics of car-following models which describe continuous feedback control tasks (acceleration and braking) and models for discrete-choice tasks as a response to the surrounding traffic. The driving style of an agent is characterized by model parameters such as reaction time, desired speed, desired time gap, anticipation etc. ...

Abstract
During the last few years, continuous progresses in wireless communications have opened new research fields in computer networking, aimed at extending data networks connectivity to environments where wired solutions are impracticable. Among these, vehicular traffic is attracting a growing attention from both academia and industry, due to the amount and importance of the related applications, ranging from road safety to traffic control, up to mobile entertainment. Vehicular ad-hoc networks (VANETs) are self-organized networks built up from moving vehicles, and are part ...

Abstract
Vehicular Ad-Hoc Networks (VANETs) enable communication among vehicles as well as between vehicles and roadside infrastructures. Currently available software tools for VANET research still lack the ability to asses the usability of vehicular applications. In this article, we present <u>Tra</u>ffic <u>C</u>ontrol <u>I</u>nterface (TraCI) a technique for interlinking road traffic and network simulators. It permits us to control the behavior of vehicles during simulation runtime, and consequently to better understand the influence of VANET applications on traffic patterns. In contrast to the ...

Abstract
New applications in future intelligent transportation systems are to enhance both safety and traffic efficiency. Wireless vehicular communication is to provide the basis for the new Vehicle-2-X communication applications. However, field tests are necessary to make them usable and validate the improvements that are to be achieved. Since the realization of the field tests is rather complex and expensive, detailed simulations are essential to prepare the tests in the real world and reduce their costs. Currently, software simulators do not support ...

Abstract
Realistic simulation is a necessary tool for the proper evaluation of newly developed protocols for Vehicular Ad Hoc Networks (VANETs). Several recent efforts focus on achieving this goal. Yet, to this date, none of the proposed solutions fulfil all the requirements of the VANET environment. This is so mainly because road traffic and communication network simulators evolve in disjoint research communities. We are developing TraNS, an open-source simulation environment, as a step towards bridging this gap. This short paper describes the ...
