Abstract

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 be routed to the downloaders through the Vehicular Network (VANET). VOPP considers the link availability between the infrastructure and the downloader, the medium contention, interferences, data volume, gateways capacity and the channel aggregation to evaluate the VANET capacity to support additional traffics. Numerical results of our analytical approach show that the data offloading fraction is closely tied to the data volume of the flows and to the vehicles positions and VANET topology.

VOPP:叶片卸载潜力预测模型
在这项工作中,我们研究了考虑将智能交通系统(ITS)用于蜂窝流量分流作为Wi-Fi和femtoCells方法的替代方案的潜力。我们提出了一个基于VOPP优化问题公式的分析研究,其目标是选择可以通过车载网络(VANET)路由到下载器的数据流的最大数量。VOPP考虑基础设施和下载器之间的链路可用性、介质争用、干扰、数据量、网关容量和信道聚合来评估VANET容量以支持额外的流量。数值结果表明,数据卸载分数与流的数据量、车辆位置和VANET拓扑结构密切相关。
