| Summary: | Vehicular Delay-Tolerant Networks (VDTN) is a spatial sort of Delay-Tolerant Network (DTN) for next generation vehicle communication. However, limited resources in terms of delivery ratio while higher
overhead are the key challenges. Therefore, a reliable with satisfying quality of service (QoS) of delay tolerable dynamic communication is required for vehicular ad-hoc networks (VANETs). This paper
evaluates the varying number of mobile vehicles/nodes and two different types of Mobility Models; Traced based Mobility and Random based Mobility Model. The above scenarios were investigated based on Epidemic routing, PRoPHET routing, and Spray And Wait flooding routing. The performances were evaluated using Network Simulator (NS-3.29) with VANETs or IEEE 802.11p standard. Finally, three QoS metrics were considered: Delivery Ratio, Overhead, and Average Delay. The simulation result shows that
the RWayPoint Mobility has recorded better performance metrics for all routing protocols in both (lower and higher) density vehicle scenarios. Hence the QoS are improved. |
