A Novel Routing Algorithm for Vehicular Ad Hoc Networks

This article examines the importance of wireless ad hoc networks and the Location Routing Algorithm with Cluster-Based Flooding (LORA-CBF) for inter-vehicular communication in the context of optimizing traffic flow and increasing motorway safety. The LORA-CBF routing algorithm is discussed and simulated in detail, considering a motorway environment with its associated high mobility. First, for small-scale networks, our proposed simulation model is validated with the results of a test bed. Then, for large-scale networks we use simulations to compare our model with both the Ad Hoc On-Demand Distance Vector (AODV) and Dynamic Source Routing (DSR) algorithms. We use a microscopic traffic model, developed in OPNET, to ascertain the mobility of 250 vehicles on a motorway. Finally, we apply LORA-CBF in a vehicular test bed.
