Embodiment Construction

[0063]In order to make the purpose, technical solutions and advantages of the present invention clearer, the following technical solutions in the present invention are clearly and completely described. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0064] The invention provides an efficient broadcasting algorithm for the Internet of Vehicles based on multi-delay optimization. In the algorithm, a node collects neighbor node information (location coordinates, moving speed and direction, etc.) through periodic HELLO data packet broadcasts. When the source node initiates a data broadcast, its neighbor nodes use the collected node information to calculate the forwarding delay time after receiving the data packet ...

Abstract

The invention provides a multi-delay optimization-based Internet of Vehicles efficient broadcast algorithm. The multi-delay optimization-based Internet of Vehicles efficient broadcast algorithm comprises the two steps of delay slot computing based on different network states and adaptive forwarding delay time computing. The multi-delay optimization-based Internet of Vehicles efficient broadcast algorithm can adapt to the complex and changeable Internet of Vehicles environment, can adaptively select an appropriate network state parameter for broadcast optimization when the network environment changes, not only keeps the high node reachable rate, but also significantly reduces the broadcast redundancy and significantly shortens the transmission delay and has the high adaptability.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, in particular to an efficient broadcast algorithm for the Internet of Vehicles based on multi-delay optimization. Background technique [0002] The Internet of Vehicles is a mobile network formed by using wireless communication technology with moving vehicles and transportation facilities as nodes. The data transmission methods in the Internet of Vehicles include unicast, multicast and broadcast. Among them, broadcasting has a wide range of important applications in the Internet of Vehicles. It can update network status information, detect traffic congestion, send emergency information, and improve driving safety through broadcasting between vehicles or between vehicles and infrastructure. However, broadcasting will cause serious problems such as high redundancy, high conflict and high delay in the data transmission process of the Internet of Vehicles, which will reduce the broa...
