Abstract
This article analyzes and compares the service quality metrics in reactive routing protocols AODV and DSR in VANET. Through the revision of the recorded information we study the characteristics, classification, applications and different traffic models. All these parameters are taken into account in the modelling of vehicular traffic in the downtown of Loja City. In order to get the corresponding results, three different scenarios each with a different node density have been created. According to the collected data, it is possible to verify which routing protocol is the most suitable for the Ad-Hoc networks proposed in this study.
Highlights
The development of wireless networks and communication systems have had a positive impact on society, especially the evolution of mobile devices as they offer great mobility to users, together with a growing offer of communication devices such as smartphones, tablets and different mobile terminals that transform on a daily basis the way people communicate. [1]Networks traditionally known as wireless have a device that manages the net and infrastructure making it possible to connect to different target devices
It is proposed to undertake a case study of two routing protocols used in Ad-Hoc networks, Ad-Hoc Demand Distance Vector (AODV) and DSR
All the corresponding information is recorded in the Request for Comments (RFC) number 3561 released in July 2003 on a trial basis and it belongs to the Internet Engineering Task Force (IETF)
Summary
The development of wireless networks and communication systems have had a positive impact on society, especially the evolution of mobile devices as they offer great mobility to users, together with a growing offer of communication devices such as smartphones, tablets and different mobile terminals that transform on a daily basis the way people communicate. [1]. Networks traditionally known as wireless have a device that manages the net and infrastructure making it possible to connect to different target devices. One of the main targets in VANET is to assure the quality of service in the use of real-time applications as data or information transfer This type of networks are well-known for being highly dynamic which causes the emergence of different topologies creating difficulties in discovering and keeping communication in the given scenarios. This brings as a result the loss of connectivity among vehicles causing a deterioration in service quality. Quality of service metrics have been measured, compared and analyzed using the Ns-3 software to simulate the different scenarios and using Manhattan Grid as the mobility model
