Vehicular Ad-hoc Networks (VANETs) dynamic performance estimation routing model for city scenarios

Abstract

Vehicular Ad-hoc Networks (VANET) is one of the most actual and challenging research area in automotive companies and ITS designers. In general, a VANET is formed from a number of vehicles which are in the same road to form ad-hoc network. The presence of such these networks opens the way for a wide range of applications such as safety applications, mobility and connectivity for both driver and passengers to exploit the transport systems in a smoothly, efficiently and safer way. For safety applications which is a critical section from VANET, the best routing protocol must be selected. Indeed, it is important and essential to test and evaluate different routing protocols that related to VANET system before apply them in the real environment which can be done via VANET simulation tools. This paper evaluates the performance of three different routing protocols for VANET system in city of Khartoum. The performance are evaluated and compared in terms of PDR, average throughput, delay and total energy. Our objective is to estimate the performance of routing model for city scenario. The main goal is to find the suitable routing protocol in a high density traffic area in Khartoum. We have considered three routing protocols DSR, AODV and DSDV. The results indicate the bad performance of DSDV protocol which is a type from proactive routing protocols. The AODV protocol achieves maximum average throughput which is equals to 330.07Kbps. The minimum value of delay is obtained from using DSR protocol was 15.81 ms.
