Abstract

VANETs are enhanced and upgraded versions of mobile ad-hoc networks which are fruitful for intercommunication vehicles. Communication can be vehicle-to-vehicle and between vehicles to side-fixed equipment known as roadside equipment. This network is self-organized, highly dynamic but separated without any infrastructure or client and server communication. The objective of this research is to examine the study of TwoRayGround and Nakagami radio propagation models for vehicular ad-hoc networks in Indian Scenarios as well as to find the best efficient model, which is more suitable in various scenarios. Output of this research will be beneficial for applying efficient models on the realistic highway scenario, especially traffic caused by four wheelers. This model will also be fruitful for avoiding heavy road congestion and highway road accidents caused by a high and unbalanced speed of traffic as well as other various road conditions, like pot holes and road barriers, etc.

The earliest research on the inter-vehicular communications as described in (Tsugawa, 2005) was conducted by Association of Electronic Technology for Automobile Traffic and Driving (JSK) of Japan in the early 1980s that is now known as the Japan Automobile Research Institute (JARI) (http://www.jari.or.jp). This study analyzing the performance of ad-hoc routing protocols from different characteristics. Scholars (Broch, Maltz, Johnson et al., 1998) compared four ah-hoc routing protocols TORA, DSDV, AODV and DSR in terms of overhead of routing, packet delivery ratio and path optimality.

The author Qian Feng et. al. (Feng, Cai, Yang et al., 2009) analyzed the performance of AODV, DSR, and DSDV and OLSR routing protocols using the NS-2 simulator and find out that DSDV and OLSR to perform better in the small networks and AODV and DSR are more efficient, adaptable and convenient in the networks that have large scalability.
