Abstract

The invention discloses a highway vehicle network broadcast algorithm based on real-time successful broadcast rate and distance. With each vehicle as a node in the broadcast, the broadcast communication between nodes calculates the forwarding probability of the current node according to the real-time successful broadcast rate of the current node and the distance between the current node and the previous hop node, and then sends broadcast packets according to the forwarding probability , and update the broadcast packet sending and receiving record table, the sent broadcast packet record table and the successfully broadcast packet record table in real time during the mutual broadcast communication process between any two nodes. The present invention can effectively suppress broadcast grouping, improve broadcast reliability, and has short average transmission time delay, and is a vehicle-mounted ad hoc network broadcast algorithm that is better applicable to expressway scenes.

Description

technical field

[0001] The invention belongs to a broadcasting method in the field of wireless networks, and in particular relates to a broadcasting method for a vehicle-mounted self-organizing network on a highway based on real-time successful broadcasting rate and distance. Background technique

[0002] Vehicle ad hoc network is a special mobile Ad Hoc network, which is a wireless network composed of a group of vehicle nodes with wireless transceiver functions. Nodes in the network function as hosts and routers. When the destination node is not within the coverage of the source node, broadcast packets can be transmitted to the destination node through multi-hop communication. Vehicle self-organizing network not only has the characteristics of mobile Ad Hoc network without central control node, automatic networking, multi-hop routing, etc., but also has its own unique characteristics, such as: network topology changes quickly, vehicle movement trajectory has certain predict...
