An Efficient Packet Forwarding Mechanism Based on Bandwidth Prediction with Consideration of V2I and V2V Communications

In order to support users who are transporting by vehicles, more efforts are on the technology of vehicular networks. The high mobility and topology diversity of networks are the major challenges to develop technology for vehicular networks. For the sake of obtaining the status of vehicular networks in real time and estimating the quality of network connections accurately, this paper proposes an available real-time bandwidth estimation mechanism based on the properties of vehicular networks. By detecting the number of users within the transmission range and the mobile information provided by the vehicles, our paper focuses on accurately estimating the efficiency index of network connections. In this paper, we also propose an efficient packet forwarding mechanism to improve the transmission quality of network services requested by users and to enhance the overall network performance. The simulations are done to show the improvement of our proposed method.
