This paper proposes an analytical throughput model for IEEE 802.11-based vehicle-to-infrastructure networks with asymmetric traffic. Previous models assume all nodes use ad-hoc mode with uniform traffic without mobility. This model is developed using the fixed-point analysis, which assumes asymmetric traffic loads for AP and clients, and both types of traffic are nonsaturated. The mobility effect is also considered, which is modeled as a throughput scaling factor taking account of velocity and communication range. Numerical evaluation compared with Bianchi's model, verifies the proposed model and quantifies the difference caused by asymmetric traffic, and the throughput with mobile nodes is evaluated with the increase in velocity.
