Assessment of Video Communication for QoS in Vehicular Ad Hoc Networks

Vehicular ad hoc network (VANET) is one of the largest areas of interest in wireless technology because it provides very wide variety of services in the field of transportation. Intelligent Transportation System (ITS) provides a set of standards for Vehicular Communication networks. The vehicular network provides many useful applications and advantages. The multimedia applications, which are based on vehicular network, are considered to play a very vital role in the future of ITS, but now-a-days they are facing some big challenges on Quality of Services (QoS) issues due to high velocity, network scalability and limited communication range. In this paper, the evaluation of Quality of Videos and services has performed by using proactive, reactive and hybrid routing protocols under different network conditions, in various communication environment using QualNet simulator. Here, the authors have presented the combination of two results of this assessment. The results are considered that which routing protocol is more suitable and determines that which network condition is better in which vehicular network environment provide efficient QoS and video streaming performance. Finally, the authors try to increase the performance of videos and improve the Quality of Services of ITS over vehicular networks in the future.
