Capacity of Vehicular Ad Hoc Networks Based on Multibeam Directional Transmission

The development of multibeam directional transmission technology used in vehicular ad hoc networks is drawing much more attention in recent years due to its wider coverage ability than omnidirectional transmission. In this paper, we analyse the transport capacity of the vehicular network using diffe...
