Análisis y documentación de la implementación de la capa física IEEE 802.11a y 802.11p para redes ad hoc en el simulador OMNeT++

Abstract

Nowadays, both MANETs (Mobile Ad Hoc Networks) and VANETs (Vehicular Ad Hoc Network) are a subject of study due to the mobility they offer. Performing the study of this type of adhoc networks in real scenarios is complicated and expensive, so the use of network simulators is necessary. OMNeT ++ is one of the most used network simulators, which allows the researcher to study and evaluate adhoc networks through the INETMANET and Veins frameworks. To guarantee the reliability of the results obtained through the simulator, it is necessary to appropriately model the physical layer, so this project focuses on the study and analysis of the implementation of the physical layer of the frameworks at the code level. The objective is to identify the base structure of each framework allowing to establish how its different components interact and allowing to explain how the transmission/reception process is performed by diagrams. In this way, the differences that OMNeT ++ has, in terms of the IEEE 802.11a and IEEE 802.11p standard for simulating adhoc networks, are determined. Additionally, scenarios included in INETMANET and Veins are simulated to evaluate the performance of the throughput and average delay with different propagation models, number of nodes and speed. Then, variables and code necessary for the calculation of throughput and delay are inserted, and files are modified.
