— Vehicular networks are emerging as an exciting new area of pervasive networking. Roadway congestion amelioration is one of the attractive applications of such a network. The mobility of vehicles on the roadway has been modeled in literature, but the effect of the communication network on the mobility patterns has not been addressed so far. We present such a model of the mobility that integrates the effects of the network. Our model is based on an earlier model using a Enskog dense gas modeling of the traffic flow. Our solutions show that the model is realistic and numerical simulations also verify the results. We also note that this application can cause oscillation waves in the traffic flow, which have so far not been recognized in literature.
