Link analysis of VANET in interchanges of expressway

In recent years, the Vehicular Ad-hoc Networks(VANET) is growing rapidly. There are many applications of the VANET. Especially, the VANET is applied to in the urban-roads and expressways. In this paper, a city is considered as well as the expressway scenario while the analzing the communiation between the street-aware information with vehicles. The length of the vehicles is considered to analyze the communication among cars including those not only waiting at the traffic square but also passing through after obtaining the traffic signal clearly in the interchange. We describe the scenario of interchange of expressway and utilizes the simulation in order to provide useful information.The result of the experiment analysis shows that we simulate average end-to-end delay and packet delivery ratio in the interchange of expressway. We will combine different theories of vehicle in the future work.
