Approaching P2P communication in a vehicular ad hoc network

This paper introduces P2P communication across a VANET and seeks to establish under what conditions (mobility, network size, wireless channel) data streaming is feasible. Routing of streamed services over multiple hops and multiple paths may result in significant packet losses, resulting in unacceptable quality of service. This paper examines the impact of differing traffic densities and different road layouts upon a P2P overlay network. The work modeled the emerging IEEE 802.11p for vehicular networks. It is shown that the mobility pattern of the vehicles involved needs to be closely modeled to determine signal reception patterns, as does the wireless channel environment, to avoid over optimistic assessment of communication within a VANET.
