Abstract

Abstract : Clustering is considered an important issue in Vehicular Ad‐hoc Networks (VANETs) to ensure the network robustness and throughput. Nevertheless, in the literature, there is still a lack of understanding of how relative mobility between cluster members and the cluster head affects the throughput of VANET clusters. In this letter, we present a model to characterize the throughput of VANET clusters, by taking into account the relative mobility effect, which implicitly accounts for the Doppler effect. The numerical analysis shows that there is a large gap between the throughput of the model with/without consideration of relative mobility, which indicates the necessity to develop clustering algorithms that minimize intra‐cluster mobility.
