In this paper, we propose a cooperative traffic transmission algorithm in a joint cellular and mobile ad hoc hybrid network architecture. The mobile ad hoc network is based on IEEE 802.11p standard. The focus of this paper is on defining an algorithm aiming to select the appropriate gateway for a given source vehicle under the scope of V2I communications.(More)
FemtoCells' deployment presents a major challenge. In fact, these femto-base stations are often seen as hostile interferers by macroCells. Therefore, the optimization of the radio resource allocation to femtoCells is essential to decrease the interference in the network and provide a better QoS for both femtoCell and macroCell users. In this paper, we(More)
In this paper, we propose a new dynamic frequency assignment scheme for femtoCells in OFDMA networks. The femtoCell base stations are small cellular base stations specially designed to improve the poor indoor coverage and increase the system capacity for cellular and wireless broadband networks. However, these femto-base stations cause harmful interference(More)
In this work, we investigate upon the potential of considering the Intelligent Transportation Systems (ITS) for cellular traffic offloading as an alternative to Wi-Fi and femtoCells approaches. We propose an analytical study based on an optimization problem formulation called VOPP where the objective is to elect the maximum number of data flows that could(More)
Due to the high user traffic demand increase, offloading cellular traffic through other kinds of networks, such as Wi-Fi hotspots and femtoCells has been highly studied. In this paper, we investigate upon the possibility to use Vehicular ad hoc Networks (VANETs) for the offloading the cellular infrastructure. We present an analytical study based on an(More)
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(More)
