Abstract

In this paper, we address the gateway selection issue in a hybrid system composed of a VANET network and a 4G LTE Advanced infrastructure. The VANET network is structured via a clustering scheme. Our algorithm is based on a multi-criteria and QoS related attributes approach used to make a decision of the appropriate gateway that might be used to connect a source vehicle to the LTE Advanced infrastructure. Considered criteria for making the decision include load, Received Signal Strength and Link Connectivity Duration of the cluster head and other candidate gateways. Simulation results demonstrate that our algorithm makes efficient decisions for electing the appropriate gateway with the best VANET and infrastructure features.
