Design of Low Energy Consumption of Communication Module in Highway Environment
Under the environment of expressway,the communication module of vehicle-road cooperative system faces the problem of high energy consumption,which affects the continuous operation ability of the system.Aiming at this problem,this paper proposes a design scheme of low energy consumption.Firstly,the energy consumption of the communication module is analyzed,and then the low energy consumption of the communication module is realized from three aspects:dynamic power regulation,hierarchical sleep and wake up and lightweight data compression algorithm.The experimental results show that the scheme can effectively reduce the average transmission power,power consumption and transmission energy consumption of the communication module,and ensure the communication quality.This study provides technical support for the long-term stable operation of the highway vehicle-road cooperative system.
