Evaluación de protocolos de encaminamiento en redes VANET conectados mediante 802.11p considerando modelos de movilidad sintéticos y generadores de tráfico vehicular.

Abstract

This research work aimed to evaluate the routing protocols in VANET networks connected through 802.11 p, by considering the synthetic mobility models and vehicular traffic generators. Based on the data collection, the Manhattan and IDM models were selected, thus several platforms were installed as well at the OS Ubuntu 12.04: SUMO for the vehicular traffic, NS-2 for data network and MOVE for exporting the SUMO information to NS-2. Some routing agreements were used such as reactive and proactive in order to apply the DSDV and AOMDV protocols, hence by making a comparison these ones were which shown the best features. At the simulation sceneries, a low, medium and high connection numbers were applied, with two kinds of communication (V2V, V2I) for VANET networks. The indicators used for determining the protocols performance were Throughput, PDF, Average End to End Delay and NRL. For V2V communications regardless of connections or mobility models, AOMDV or DSDV protocols can be easily used because there is a minimal difference, being AOMDV a bit higher than DSDV and suitable for V2I communications. As conclusion, the most real model is IDM due to it is based on a traffic generator, the Manhattan model offers ambiguous results because it is synthetic and uses mathematical formulas. When using MOVE, it is recommendable to compile the file .sumo.tr in order to export data to NS-2 without drawbacks and establishing the nodes connections by means of command designs at .tcl file to optimize the setting timing.
