Congestion Control Method of New Energy Vehicle Vehicle Communication Network
Congestion is a common problem in the communication network of new energy vehi-cles,and congestion control is one of the transmission technologies in the communication net-work.This study identifies vehicle communication network congestion based on the mechanism of congestion generation,optimizes the queue length of communication services by prioritizing communication network services,and then uses adaptive weight coefficients to perceive the link state of the communication network.By estimating the available bandwidth of the communica-tion network and the optimal congestion window length,vehicle communication network serv-ices are allocated and the transmission path of the vehicle communication network is optimized.Experimental results have shown that this method improves the throughput of vehicle commu-nication networks,shortens end-to-end time,and has good congestion control effects.
