Safer, more efficient, and more comfortable automotive transport are the primary goals of Intelligent Transportation Systems (ITS). Dedicated Short Range Communications (DSRC) wireless links between vehicles, transit authorities, and consumer service providers will provide the communications infrastructure to realize these goals. The IEEE 802.11p WAVE, Wireless Access for the Vehicular Environment, standard is currently being developed to provide high rate, mid-range, mobile wireless connectivity.

Research of these emerging vehicular ad-hoc networks (VANET) has become increasingly pertinent. Safety applications are of particularly high priority for ITS. Consequently, the accuracy and applicability of VANET performance analysis to real-world scenarios is of utmost importance. Unfortunately, the shear complexity of VANETs often precludes direct analysis and encumbers efficient simulation.

Application, network, medium access, and physical layers interact with each other and channel and mobility models to realize a VANET simulation. Our research investigates the cross-layer interactions between various layers and the environment. We identify parameters critical to performance and develop simulation models to account for these parameters. Algorithms are designed cognizant of cross-layer affects and top layer performance constraints.
