Abstract

In this paper, different heuristics for cross-layer optimization for vehicular ad-hoc network are reviewed and analysed. Up to a large extent safety issues and traffic congestion in daily life can be resolved by integrating information and communication methodology into transportation infrastructure and vehicles. Link maintenance due to high mobility, congestion control, self-organization, dynamic behaviour and scalability makes it stiff to deployment in real time scenario. Performance of the different routing protocols in different scenarios are observed using different simulation tools by different authors in literature. It has been observed from the study that transmission range, obstacles, speed, scalability and road condition influence the performance of different protocols. Quality of Service metrics parameters like speed and mobility of vehicle influence the performance of network. For enhancement of the network performance in real time scenario latest communication technology and infrastructure plays an important role. Packet delivery ratio, goodput and throughput of vehicular ad hoc network can be improved by using optimized link prediction heuristic observed by simulation.
