| Summary: | A data transmission algorithm of vehicle Ad Hoc network based on channel switching (DTA) was proposed.In the DTA,three network layers were considered,such as vehicle nodes,relay nodes and sink nodes.The vehicle nodes were classified by the information of vehicle’s driving direction.The vehicle nodes channel distribution and switching mechanism was proposed to reduce the interference of communication.Then a rapid transmission of relay nodes was proposed.A priority transmission method for emergency information was proposed to classify data with different queues and send data as their queues’ priority.Simulation results show that DTA can effectively achieve the rapid transmission of useful information,reduce unnecessary losses of energy,improve the data received rate of sink nodes,reduce the average hop number of data packets and improve coverage rate of data transmission.Under certain conditions,DTA is better than AODV and AODV-L algorithm,and is more suitable for vehicle driving environment of rapid change. |
