An Efficient Broadcasting Algorithm for Internet of Vehicles Based on Multiple Delay Optimization

Abstract

The present invention provides a multi-delay optimization-based high-efficiency broadcast algorithm for Internet of Vehicles, which includes two steps: calculation of delay time slots based on different network states and calculation of adaptive forwarding delay time. The present invention realizes the high-efficiency broadcast algorithm of the Internet of Vehicles based on multi-delay optimization, which can adapt to the complex and changeable Internet of Vehicles environment, and can adaptively select suitable network state parameters for broadcast optimization when the network environment changes, not only maintaining a higher node Reach rate, and significantly reduce broadcast redundancy and transmission delay, with strong 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...
