“…In order to simplify the model's implementation into a numerical simulation environment, the G y distributions can be re-sampled to integer values of the simulation's timestep; for example, the simulation framework based on SiVIC that we used in previous research [18] has a timestep of 5 milliseconds. Given this latter information, the pseudoalgorithm used is the following: Fig.…”

“…Our goal is to develop a model to simulate performance indicators (frame loss, latency) based on empirical data and that can be implemented directly inside the software used to simulate cooperative applications (in our case, the SiVICRTMaps framework [12], [13]). Such a model would bridge a gap between physical layer and network models by providing a focus on some simple, yet central, performance indicators for IEEE 802.11p in small-to-medium-sized networks where no routing (or complex topology) is required; it is entirely focused on delivering realistic performance indicators to upper-layer cooperative applications simulations.…”

Abstract-IEEE 802.11p is the new standard for InterVehicular Communications (IVC) using the 5.9 GHz frequency band, as part of the DSRC framework; it will enable applications based on Cooperative Systems. Simulation is widely used to estimate or verify the potential benefits of such cooperative applications, notably in terms of safety for the drivers. We have developed a performance model for 802.11p that can be used by simulations of cooperative applications (e.g. collision avoidance) without requiring intricate models of the whole IVC stack. Instead, it provide a a straightforward yet realistic modelisation of IVC performance. Our model uses data from extensive field trials to infer the correlation between speed, distance and performance metrics such as maximum range, latency and frame loss. Then, we improve this model to limit the number of profiles that have to be generated when there are more than a few couples of emitter-receptor in a given location. Our model generates realistic performance for rural or suburban environments among small groups of IVC-equipped vehicles and road side units.

Abstract-Cooperative Systems provide, through the multiplication of information sources over the road, a lot of potential to improve the assessment of the road risk describing a particular driving situation. In this paper, we compare the performance of a cooperative risk assessment approach against a non-cooperative approach; we used an advanced simulation framework, allowing for accurate and detailed, closeto-reality simulations. Risk is estimated, in both cases, with combinations of indicators based on the TTC. For the noncooperative approach, vehicles are equipped only with an AAClike forward-facing ranging sensor. On the other hand, for the cooperative approach, vehicles share information through 802.11p IVC and create an augmented map representing their environment; risk indicators are then extracted from this map. Our system shows that the cooperative risk assessment provides a systematic increase of forward warning to most of the vehicles involved in a freeway emergency braking scenario, compared to a non-cooperative system.
