This paper presents an Infrastructure Enhanced Geographic Routing Protocol (IEGRP) for urban vehicular environments. IEGRP is a hybrid vehicular routing protocol that facilitates V2V or V2I unicast routing by dynamically changing its routing decisions in the presence of full or partial Road-Side Unit (RSU) infrastructure in order to maximise packet delivery rate. To the best of the author's knowledge this is the first hybrid approach where the routing algorithm exploits the presence of infrastructure where available but also utilises efficient multi-hop communications using greedy forwarding, store and forward buffering and predictive link stability techniques. IEGRP is evaluated using realistic vehicular radio propagation and movement conditions and demonstrates much improved delivery rates with partial and full infrastructure compared to related protocols.
