Overhauling ns-2 PHY/MAC simulations for IEEE 802.11p/WAVE vehicular networks

The IEEE 802.11p/WAVE family of standards has been designed to provide multi-channel communications for vehicular use. Despite the increasing interest on vehicular networking, further efforts are still required to improve realism of simulations, in order to account for the latest standards and for physical-related phenomena. In this paper, we aim at overhauling the physical and MAC layers of ns-2 to include the last recommendations on frequency allocation, the effects of channel impairments (fading, obstructions, in-channel and adjacent channel interference), an enhanced receiver design, and the WAVE multi-channel related effects.
