“…The model in [3] accounts for urban obstructions and has been integrated into the widely used network simulator NS-2 [7]. There it has been justified by measurements from literature and here is validated by means of ray-tracing software, confirming the reliability and accuracy of the additional attenuation values selected for urban simulations.…”

“…The solutions proposed in [3][4][5] share a common idea: additional attenuations are introduced based on mutual positions of nodes to account for propagation obstructions and residual propagation due to diffractions and scatters.…”

“…Important improvements have been recently proposed to increase the realism of simulations: the new features include mobility patterns matching real maps [9], detailed receiver models accounting for Viterbi errorrecovery [10] and obstruction models accounting for the presence of buildings [3][4][5] and for the impact of vehicles acting themselves as obstacles [11]. According to [10], the impact of obstructions appears to be the most relevant.…”

“…Despite very complex, these phenomena have been recently demonstrated to be effectively simulated by simple (and not simplistic) models [3][4][5]. While the suggested models are straightforward, they adhere to and are validated by existing measurements [4,6] and, what makes them relevant, can deeply influence and change the results.…”

Vehicular ad-hoc networks are expected to be a key enabling technology for the development of future Intelligent Transportation Systems (ITSs), by delivering a wide range of services, spanning from safety alerting to route guidance and entertainment. Most of ITS applications require vehicles on the road to access the Internet through wireless communications with road-side units. The high vehicle mobility coupled with the large amount of investments required for deploying a complete roadside infrastructure will cause vehicle-to-roadside (V2R) connectivity to be poor, short-lived, and intermittent by negatively affecting the performance of envisioned applications. The purpose of this paper is to gain a deeper insight into possible issues related to service access and provisioning when considering the multi-channel operations envisioned by the IEEE 802.11p/WAVE (Wireless Access in Vehicular Environments) standards. We investigate network connectivity offered by roadside and moving WAVE providers in a realistic urban scenario where wireless propagation is hindered by obstructions. Results prove that hybrid solutions complementing roadside providers with moving ones lead to improved connectivity and data delivery performance, by potentially incurring lower deployment costs.
