Abstract

Vehicular ad hoc networks have the characteristic to of experiencing rapid change of network topology and mobility. Importantly, vehicular networks are required to deal with different network densities in order to provide efficient routing and data dissemination. These are some of the main characteristic that can affect the performance of the network immensely. The main issue that became the driving factor in implementing this project is the need to fill these gaps of understanding the behavioral of vehicular network performance when they are restrained by certain network condition which in this case, dealing with an obstruction of road infrastructure with varying transmission range and node density.
In order to understand this problem, we identify the objectives of this project to integrate SUMO/MOVE (a vehicular traffic generator) into NS-2 to simulate a realistic vehicular ad hoc network environment and to study the performance of the network when the being conditioned into varying settings of transmission range and node density. In this project, we evaluate the network performance of VANETs in a highway environment using SUMO traffic simulator and network simulator, NS-2 which specifically focusing at the toll booths by studying the effect of varying transmission range over node density. From the simulation results, we found out that the smaller transmission range will produce less throughput, higher end to end delay and also higher normalized routing load. Particularly in vehicular ad hoc network, a constant or a fixed transmission range is not efficient enough in maintaining the connectivity in the network. This is due to the unpredictable of traffic conditions in the network. In addition to this, by dynamically changing the transmission range according to its need, will offer the advantage of power saving and increase capacity.
