Abstract

The invention provides a method and a device for transmitting a data packet, which is used for solving a technical problem existing in the prior art of poor reliability in data transmission between vehicle-mounted equipment in a vehicle ad hoc network. The method comprises the steps that first vehicle-mounted equipment sends a data packet to second vehicle-mounted equipment through the vehicle ad hoc network; and the first vehicle-mounted equipment does not receive a response message from the second vehicle-mounted equipment before reaching a preset length of time, and the first vehicle-mounted equipment sends the data packet to the second vehicle-mounted equipment through a mobile communication network.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for transmitting data packets. Background technique [0002] With the development of communication technology, the vehicle ad hoc network routing is realized through short-distance communication and road-side units (Road-Side Units, RSU) assistance, that is, through the DSRC (Dedicated Short Range Communication, dedicated short-range communication technology) for vehicle ad hoc network routing, or with the assistance of RSU for routing. [0003] However, due to factors such as high-speed movement of vehicles, rapid changes in network topology, and frequent failures of links between nodes, coupled with problems such as local optima and local loops that may exist in the data pathfinding process, the vehicle-mounted equipment in the VAN The reliability of data transmission between them is poor. Contents of the invention [0004] The present invention provides an inf...
