An Applicability of AODV and OLSR Protocols on IEEE 802.11p for City Road in VANET

Abstract

Vehicular Ad-hoc Network (VANET) improves, makes more safe and comfortable road transportation by using vehicular communication and the Internet. VANET is the subset of Mobile Ad-hoc Network (MANET). Thus, due to their similar characteristics, MANET routing protocols may also be applicable into VANET. Hence, the performance of MANET routing protocols should be evaluated only on IEEE 802.11p communication standard, which is specifically designed for VANET communication, with urban and non-urban vehicular traffic. This work compares the performance of Ad-hoc On-Demand Distance Vector (AODV) routing protocol with Optimized Link State Routing protocol (OLSR) on two different road network scenarios, particularly a complex road network, which represents the city road network, having multiple crossroad and an intersection of two roads. We used two distinct simulators such as Vehicular Ad-hoc Networks Mobility Simulator (VANETMOBISIM), to simulate the city road network and vehicular traffic in an area of 700mx700m and NS-2.35 network simulator to simulate the communication network. AODV and OLSR performances are assessed on different transmission range, i.e. 250m and 500m with four different data generation rate of 512, 1024, 1536 and 2048 Kbps.

The primary goal of this work is to do an assessment to scrutinize the applicability of AODV and OLSR protocols in VANET with different traffic scenario and transmission ranges of IEEE 802.11p standard.
