On Multi-hop Forwarding over WBSS-based IEEE 802.11(p)/1609 Networks

The IEEE 802.11(p)/1609 network is a promising candidate for future vehicular communication networks. Due to the deployment cost consideration, roadside units (RSUs) in such networks are usually installed only at hot spots and intersections, causing the service coverage of RSUs to be discontinuous. To overcome this problem, multihop data forwarding among vehicles can be used to extend the service coverage of RSUs. In this paper, we propose a receiver-centric WBSS (Wave Basic Service Set)-creating scheme to support multihop data forwarding in WBSS-based IEEE 802.11(p)/1609 networks and evaluate its performances using simulations. Our simulation results show that this scheme outperforms a typical sender-centric WBSS-creating scheme on end-to-end flow goodputs under different traffic loads.
