Effect of Roadside APs in VANETs: A Comparison Study

In recent years, Vehicular Ad-hoc Networks (VANETs) have emerged as a unique type of MANETs. VANETs are an important component of the Intelligent Transportation Systems (ITS). They can been utilized to guarantee road safety, avoid potential accidents and create new forms of inter-vehicle communications. In this paper, we investigate the performance of OLSR protocol for video streaming application. The simulations are conducted in urban environment in two scenarios, where roadside Access Points (AP) are present and not present. We consider 802.11p standard and send multiple video streaming flows over UDP. We use throughput, delay and jitter as evaluation metrics. Based on simulation results, we noticed that transmission for streaming is improved when roadside AP are used.
