To solve the problems of the low utilization of the spatiotemporal resource in DA and unbalance service of cooperative downloading,a strategy of selecting cooperative vehicles named DSMov is proposed in this paper.DSMov utilizes the two-dimensional matrix to define the spatio-temporal resource of DA and the action to select vehicles,and simplify the space of behavior to select vehicles for reducing computation complexity according to the characteristic of VANET.By building optimization model of Markov Decision Process,DSMov solves the problem of the spatio-temporal resource allocation in DA.In addition,Euclidean Distance and Manhattan Distance are utilized as another principle to selecting the vehicles in order to keep the fairness of system. Simulation results indicate the benefits of the proposed scheme in terms of increasing throughput and reducing the influence from intermittent connectivity.
