Study on mobility models in vehicular communication system

Vehicles equipped with wireless communication devices are poised to deliver vital services in the form of safety alerts, traffic congestion probing and on-road commercial applications. The selection of the most realistic and the most easy-to-implement mobility model is very crucial for the validity and feasibility of research. It is described several mobility models that represent mobile nodes whose movements are independent of each other below. Based on Manhattan mobility model and no-boundary simulation region mobility model, a vehicular mobility model is proposed for ad hoc network. While vehicular simulator has been developed under the vehicular communication system, it is important to use realistic traffic density, speed, trip, and communication models. The simulation shows that the vehicular mobility model suits the vehicular communication environment suppose.
