Abstract
Vehicular networks are an emerging field of study that brings many new features to support road transportation. In this paper, we evaluate the performance of three well-known routing protocols in vehicular networks, using NCTUns, a popular network simulator. We study those protocols by changing different metrics such as node mobility, number of vehicles, traffic pattern, and number of RSUs. We also report the total elapsed time for simulations and memory consumption with the aim of guiding researchers in their selection of an adequate routing protocol for large simulation scenarios using NCTUns in vehicular networks.
Highlights
Vehicular networks are a promising and emerging technology that integrates the capabilities of wireless networks to vehicles
The implementation of some Mobile Adhoc Network (MANET) routing protocols (ADV, Destination-Sequenced Distance Vector (DSDV), and Dynamic Source Routing (DSR)) in National Chiao Tung University network simulator (NCTUns) v6.0 used a /24 netmask, which limits the number of nodes in the simulations
In our last simulation case with 200 vehicles, we vary the number of Road Side Units (RSUs) in the City Road Scenario to see the impact of the presence of devices with high network requirements, over the routing protocols
Summary
Vehicular networks are a promising and emerging technology that integrates the capabilities of wireless networks to vehicles. The majority of the simulations reported in research papers to evaluate the performance of MANET routing protocols for vehicular networks has a small number of vehicles or is based on the random movement of the vehicles, which are not the real life conditions. We make a comparative analysis, focused on vehicular networks, of three well-known routing protocols (ADV, AODV, and DSDV) with a famous network simulator called NCTUns. Unlike most of the previous work, we run our simulations on realistic scenarios with a high number of vehicles. The results of our simulations seem to indicate that ADV is performing better than the other two routing protocols for vehicular networks.
