The new modified version of mobile Ad hoc Network called "Vehicular Ad hoc Network" (VANET) which considered as one of the projects of "Internet of Things" (IOT). VANET aims to employ and utilize ad hoc technologies to alleviate Road Congestion in real time. It has a great impact on the society by reducing travel time, fuel consumption, passenger's life and finally to save money. In VANET's environment, the word Vehicle represents an intelligent node with a capability to communicate with mobile neighbors in the network. VANET introduces more challenges aspects as compare to Mobile Ad-Hoc Network (MANET) because of high mobility of nodes and fast topology changes in VANET. Several routing protocols have been designed and presented by researchers after considering the major challenges involved in VANETs. In this work several approaches: (Broadcast approach, Clustering approach, Table-Driven approach and Queering road approach) are suggested. Net logo simulator is proposed to be used in programming, designing, creating and implementing several structures for different road maps.
