Análisis del rendimiento de los protocolos OLSR, DSDV y AODV en una red MANET

Abstract

This paper presents an analysis and comparison between the proactive routing protocols OLSR and DSDV and the reactive routing protocol AODV in a MANET network. Two scenarios were defined, the first one representing a soccer team attacking and the second one defending. To simulate each scenario the area of movement of the nodes (players) was varied. For this purpose, an investigation was carried out on the problems presented by these routing algorithms for Ad Hoc networks in different environments. In this way, an overview of the strategies and solutions that currently exist is obtained. Based on the information gathered, it is proposed to perform a simulation using NS3 in order to obtain results that resemble reality. The comparison is made based on throughput, PDR and Delay metrics. In each simulation, parameters such as node velocity and initial position are adjusted according to the behaviour of a real soccer player. The nodes move in a random trajectory within the specific area and one of them sends data to a fixed server node located at the edge of the area where the nodes move, simulating the bench where the receiver is located. The transmitted traffic is characterized to simulate realistic biometric data. From the results, it is concluded that AODV and DSDV have better performance than OLSR and the optimum transmission interval is 20 seconds. In addition, with a transmit power of 10 dBm, 100% throughput is guaranteed at the receiver.
