Abstract: The upcoming IEEE 802.11p/Wireless Access in Vehicular Environment (WAVE) standard is intended to provide wireless access to vehicles on the roads. According to it, safety/control messages are delivered on a given frequency during a common control channel (CCH) interval. The rest of the time, vehicles switch over one of available service channels (SCH) for non-safety-related data exchange. Despite the massive research effort onto reliable and timely dissemination solutions for safety-related data, few works have investigated non-safety data delivery when considering the WAVE features and capabilities. In this work, a simple and easy-to-deploy channel reservation scheme based on cooperation among vehicles has been designed, which fully leverages the 802.11p/WAVE multichannel capability. Simulation results show that the proposed solution, by adding just few modifications and little-to-none signalling overhead compared to the standard, is successful in improving the performance delivery of non-safety services under several network topologies and different traffic loads.
