摘要：In a Vehicular Ad-hoc Network (VANET), vehicles communicate with each other and possibly withroad-side infrastructure nodes. Node connectivity and the amount of data that can be exchanged are limited by theduration and quality of the communication links established among nodes, which are determined by the space and timedynamics of moving vehicles. We analyze the connectivity dynamics of vehicular ad-hoc networks in a genericsignalized urban route. Given the velocity profile of an urban route as a function of space and time, we utilize a fluidmodel to characterize the general vehicular traffic flow, and a stochastic model to capture the randomness of individualvehicle which is determined by Mesoscopic,and Microscopic mobility model.Mesoscopic is a technique which is usedto find time headway between two vehicles and microscopic technique is used to find a distance headway between thetwo vehicles.
