Load Balancing and QoS-Aware Network Selection Scheme in Heterogeneous Vehicular Networks

With the increasing demands for various wireless communication technologies and standards, new challenges arise in seamless connectivity among different techniques. Mobility management protocols face a new difficulty in vehicular network heterogeneity, from deployment issues to optimal handover management process. However, due to the dynamic environment in vehicular networks, providing the best quality of service is a critical issue. Additionally, conventional mobility management solutions do not consider user's preferences when selecting the next points of access. In this paper, we present a load balancing and QoS-aware handover scheme in Heterogeneous Vehicular Networks (Het-VeNET) in order to choose the least loaded network, while maintaining the high level of required quality of service. We define the vehicle's mobility and QoS measurements and demonstrate the stated handover process in a vehicular environment. The proposed scheme performance showed a higher rate of successful handoff and load balance on different cells and scenarios when compared to benchmark schemes.
