AQUINO S, Raúl  e  B, Arthur Edwards. A Reactive Location Routing Algorithm with Cluster-Based Flooding for Inter-Vehicle Communication. Comp. y Sist. [online]. 2006, vol.9, n.4, pp.297-313. ISSN 2007-9737.

In this paper, we present a reactive location routing algorithm with cluster-based flooding for inter-vehicle communication. We consider a motorway environment with associated high mobility and compare position-based and non-position-based routing strategies, along with a limiting function for flooding mechanisms in reactive ad-hoc protocols. The performance of Dynamic Source Routing (DSR) and Ad-Hoc On-demand Distance Vector Routing (AODV) for non-positional and Location Routing Algorithm with Cluster-Based Flooding (LORA_CBF) for positional algorithms is considered. First, for small-scale networks, our research validates our proposed simulation model with the results of a test bed and the results of mathematical analysis. Then, for large-scale networks, we use simulations to compare our model with both the AODV and DSR reactive routing algorithms. Finally, we use a microscopic traffic model, developed in OPNET, to ascertain the mobility of 250 vehicles on a motorway with regards to average Route Discovery (RD) time, End-to-End Delay (EED), Routing Load, Routing Overhead, Overhead, and Delivery Ratio.
