Embodiment Construction

[0071] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0072] Such as figure 1 As shown, a broadcast flow chart of the present invention specifically includes the following steps:

[0073] Step 100, the source node sends a broadcast packet: assuming that node i is any source node that generates a broadcast packet in the network, and the source node i generates a broadcast packet with a sequence number of z, first create a corresponding entry for the broadcast packet in the broadcast packet reception record table , set the timeout T2, and record that the broadcast packet has been received under this entry;

[0074] Then encapsulate the IP address of the source node i, the serial number of the broadcast packet, the IP address of the current node i, the broadcast destination IP address, the speed and position information of the current node i in the broadcast packet header, and then send the broadcas...

Abstract

The invention discloses a vehicle-mounted ad hoc network broadcasting method based on average speed on expressways. With each vehicle as a node in the broadcast, the broadcast communication between nodes calculates the forwarding probability according to the average speed of the current node and neighbor nodes, and then sends broadcast packets according to the forwarding probability, and updates in real time during the mutual broadcast communication between any two nodes Neighbor Information Form. The invention can effectively suppress broadcast storms, has high reliability and short average information transmission time delay, and is a vehicle-mounted self-organizing network broadcasting method that is better applicable to expressway scenes.

Description

technical field [0001] The invention belongs to a broadcasting method in the field of wireless communication, and in particular relates to a broadcasting method based on an average speed vehicle-mounted self-organizing network on a highway. 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 predictability, No energy and equipment co...
