Data transmission scheme of VANET based on CH selection and switch between clusters

Abstract

A data transmission scheme based on cluster is proposed for data transmission of VANETs. Firstly, the selection scheme of cluster head CH is designed. The optimal CH is selected by calculating the utility function of CCHs, which combines node degree (NOD), available resource and mobile information of CHs and CMs, including the characteristic requirements of different user applications. According to the simulation results, the proposed scheme’s performance can be improved in terms of throughput, data transmission delay, successful transmission rate and overhead.
