“…Multiple incoming packets with low power are grouped to get the total interference of the channel, as shown in Figure 6. In this work, we employ the analytical packet error model proposed in [14], which considers signal to interference and noise ratio (SINR), channel capacity and packet length to decide if a packet is erroneous. An additional task of the physical module is setting the state of the channel as busy or idle according to the sensed power compared to the antenna sensitivity level.…”

Buildings are important elements of cities for VANETs, since these obstacles may attenuate communications between vehicles. Consequently, the impact of buildings has to be considered as part of the attenuation model in VANET simulations of urban scenarios. However, the more elaborated the model, the more information needs to be processed during the simulation, which implies longer processing times. This complexity in simulations is not always worth it, because simplified channel models occasionally offer very accurate results. We compare three approaches to model the impact of buildings in the channel model of simulated VANETs in two urban scenarios. The simulation results for our evaluation scenarios of a traffic-efficiency application indicate that modeling the influence of buildings in urban areas as the total absence of communication between vehicles gives similar results to modeling such influence in a more realistic fashion and could be considered a conservative bound in the performance metrics.

“…En [18], se realiza el ajuste de la curva de probabilidad de error de paquetes PEP en función de la SINR, longitud de paquete l y la capacidad R del canal. El ajuste se lleva a cabo a partir de resultados de simulación obtenidos con el paquete Wireless de Simulink [19].…”

“…Todas las pruebas se realizaron con el software estadístico R [20], donde se implementaron los modelos de propagación y desvanecimiento explicados en las secciones II y III. El modelo de error de paquete utilizado es el de la curva de PEP [18], debido a su alto nivel de exactitud y su sencilla implementación. Los modelos de propagación fueron configurados para que los nodos tengan un rango de alcance medio de 400 m utilizando una potencia de transmisión de 24 dBm.…”

In this paper, we review the workflow of the channel and physical layer modules in VANET simulations and briefly survey some of the most used propagation and packet error models in network simulators for this kind of networks. Through numerical simulations, we compare these propagation models working with a realistic and straightforward packet error model. Our results indicate that there is not a propagation model more conservative than the others and that a model is conservative or not depending on the channel capacity. Furthermore, different propagation models specifically designed for VANETs obtain very close results in channels with intermediate capacities.Keywords-Vehicular ad hoc networks (VANET), network simulators, channel modeling.

This paper proposes a mixed linear and integer optimization model for multi-hop ad-hoc networks to select the positions of the gateways over a certain area. This model mimics the routing behavior of such network and takes into account the maximum bandwidth capacity of the network gateways. We also include a suboptimal solution for the cases in which the complexity or the amount of the data make the optimal solution infeasible. Results in a pedestrian mesh network and in a VANET scenarios show that the model locates gateways in an efficient way and that the suboptimal solution is close to the optimal one in terms of the number of required gateways or the common selected gateways.
