NS3-based Performance Assessment of Routing Protocols AODV, OLSR and DSDV for VANETs

Abstract

A self-organized ad hoc network termed as Vehicular Ad hoc NETwork (VANET) allows each vehicle to take part in routing by sending safety-related and non-safety messages to other vehicles. VANETs have captivated many researchers’ focus as an emerging research field as it has several challenges to be addressed. The dynamic nature of mobile nodes, network latency because of link failure, and the often changing topology, adds challenges while designing a delay-efficient routing protocol in VANETs. Our study analyzes the network performance of AODV, OLSR, and DSDV routing protocol for an urban VANET scenario using the SUMO and NS3 network simulator for our university campus is presented and analyzed. To evaluate the network performance we use Packet Delivery Ratio (PDR), Packet Loss Ratio (PLR), Average Throughput (AT), Average Goodput (AG), Average End-to-End Delay (AEED), and Average End-to-End Jitter (AEEJ) as routing metrics.
