Abstract

Vehicular ad Hoc Networks (VANETs) have emerged as a key technology serving community of peoples in various applications. Providing infotainment and safety services requires the existence of road-side units (RSU) to access to the desired resources. Ideally, the infrastructure should be deployed permeatively to provide continuous connectivity and optimal coverage. This deployment technique increases capacity and coverage at expenses of increasing interference that can severely degrade the performance of the VANET. Moreover, malicious vehicles could mimic the signals of RSUs causing significant performance degradation. In this paper we study the impact of the inter-RSU interference on the beacon broadcasting due to both inefficient deployment and potential RSU emulation attacks (REA). Extensive packet-level simulations have been performed to support the observations made.
