Embodiment Construction

[0088] In order to make the above objects, features and advantages of the present application more obvious and understandable, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0089] In order to facilitate the understanding of the technical solutions provided by the embodiments of the present application, the background technology of the present application will first be described below.

[0090] The inventor found in the research on the traditional vehicle ad hoc network routing protocol that when the location-based routing protocol selects the next-hop forwarding node, it usually takes the vehicle node closest to the destination node as the next-hop. However, due to the particularity of the vehicular ad hoc network, the high-speed movement of vehicle nodes makes the network topology change drastically. Moreover, due to the influence of traffic lights, the ...

Abstract

The embodiment of the invention discloses a method and a device for realizing data forwarding. A current node can receive state data packets sent by other nodes, the state data packets can comprise road connectivity parameters and / or data queuing delay parameters, and neighbor nodes are determined according to the state data. Then, the current node selects a neighbor node closer to the destinationnode than the current node itself from the plurality of neighbor nodes as an alternative node. The priority of each alternative node is determined according to the road connectivity parameter and / orthe data queuing delay parameter of each alternative node, the node with the highest priority is taken as a next hop node, and the to-be-sent data packet is finally forwarded to the next hop node. When the current node selects the next hop node, the factors of the current road connectivity and / or data queuing delay of the alternative node are considered, and the alternative node with better current road connectivity and / or smaller data queuing delay is taken as the next hop, so that the transmission of the data packet is accelerated.

Description

technical field [0001] The present application relates to the technical field of communication, and specifically relates to a method, device, storage device, and program product for realizing data forwarding. Background technique [0002] With the development of science and technology, technologies such as electronic technology, communication technology, computer technology and automatic control technology provide new direction and support for solving traffic problems. Under this condition, intelligent transportation system came into being. The intelligent transportation system combines computer software technology, wireless sensor technology, automatic control technology and other technologies through the Internet to provide effective means for solving traffic congestion and traffic accidents. With the gradual popularization of intelligent transportation systems, VANETs (Vehicular Ad hoc Networks, vehicle ad hoc networks) designed for vehicle-to-vehicle communication have a...
