Wi-Fi is one of the solutions to overcome the explosion of mobile data traffic and improvement of Wi-Fi performance intensifies the cellular data offload to Wi-Fi. Wi-Fi AP (Access Point) selection at the STA (STAtion) is a key function to improve Wi-Fi throughput. The authors' proposed method is practical for the AP selection. If an STA can know the throughputs between the STA and surrounding APs before exchanging Wi-Fi packets with an AP, the STA can select the optimum AP that promises high throughput. In this paper, they focus on a throughput estimation method that is applicable to AP selection, and discuss the accuracy of the estimated throughput. They propose a novel Wi-Fi throughput estimation method with passive measurement and without modification for the Wi-Fi standard.
