Abstract

Vehicular Ad hoc Network (VANET) is a challenging network environment in which communication between vehicles in highly fading environments, like an urban scenario, is unpredictable and difficult. In order to analyze the performance of routing protocols and applications, a few of network simulators could be applied such as GlomoSim, NS -2, OPNET, QualNet and NCTUns. In this dissertation, we study either hindering object and signal strength in VANET could affected the performance of AODV routing protocol or not and what are the other factors affect AODV performance. The performance analysis of AODV routing protocols under hindering object and signal attenuator is presented via simulation using NCTUns network simulator based on dropped packet and throughput metrics. Beside simulation, this paper also presented comparative analysis for AODV measured by throughput and end-to-end delay. Based on simulation process and comparative analysis, it is observed that the performance of AODV is affected by physical hindering objects and signal strength. It is also observed that the performance of AODV is independent from the types of network simulator used in simulation process.

BackgroundToday, the main problem in the road traffic, especially in a big city, is traffic congestion
The practical implementation through Vehicular Ad hoc Network (VANET) simulation was performed in this dissertation
From all the graphs produced by the simulation process, we can conclude that the performance of Ad hoc On Demand Distance Vector (AODV) is affected by hindering objects and signal strength

Summary

Introduction

BackgroundToday, the main problem in the road traffic, especially in a big city, is traffic congestion. Absence of road traffic safety takes a toll of precious human lives and poses a dire threat to our environment as well. It causes the waste of energy and environmental pollution. With the use of sensor, computer and wireless communication equipment, speed could be predicted and a warning message could be sent to limit the risk of potential accidents [3]. Despite the special condition or problem that these routing protocols are considering or addressing, there is no agreed-upon standard or benchmark to validate their performance. The benchmark includes a standard routing protocol and a simulation environment. The open issue in VANET routing protocol is whether there is any benchmark tool for evaluating these protocols
