Abstract
According to a source node and a destination node of each data packet p in a given data packet set required to be transmitted by the wireless vehicular network, the joint scheduling based wireless vehicular network routing algorithm determines overall transmission performance of the wireless vehicular network and a transmission latency and transmission cost of the data packets, and determines an optimal transmission strategy. A multi-order Markov chain is used to model position change processes of vehicle nodes, and a next moment and several moments in the future are predicted and estimated under the condition that positions at previous several moments are given. On the basis of position actual values and predicted estimated values of the vehicle nodes, the optimal transmission strategy is combined to achieve data routing in the wireless vehicular network. The data-aware routing method is mainly used for data communication of a vehicular ad hoc network.
