Vehicular Ad-hoc Networks (VANETs) have emerged as an exciting research and application area. This opens the possibility of various powerful and high potential life changing applications on safety, efficiency, comfort, cooperation and participation when vehicles are on the road. VANETs have an important feature which can affect people’s life and death decisions. It is not advisable to set up and implement complicated system trials in real world before knowing the impact of all possible parameters used in VANET systems. Most of the current navigation applications, based on Global Positioning Systems (GPS), only use static information for route planning, which have no scope for real time traffic events. The researchers working in the field of VANET are not able to use software tools realistically to assess the applications of VANET. In this work, it has been shown that, if Traffic Simulator (TS) and Network Simulator (NS) are bi-directionally coupled then traffic congestion can be avoided by dynamically re-routing the vehicles. A simulation has been developed using server-client architecture in order to bi- directionally couple TS and NS. The outcome shows reduction in travel time which, in turn, reduces the fuel consumption and environmental pollution. Hence, it is capable of generating realistic simulation of real world traffic problems while testing Inter Vehicular Communication (IVC) networks.
