| Abstract(in English) | Recently, it is becoming important to grasp and improve the communication quality in a cellular data service as the market grows. In regard to the TCP throughput, a major communication quality metric, there are a variety of active measurement methods for wired environments. However, it is diffcult to apply them to cellular networks whose bandwidth resources are limited, because most of these techniques transmit a large amount of probing packets. Although some estimation methods use small amount of probing packets, it is still a challenge to apply them for wireless environment due to its unstable availability of bandwidth resource. Furtheremore, these method cannot estimate TCP throughput directly. In this paper, we propose a method to estimates TCP throughput in cellular networks based on the propagation time of probing packets with multiple sizes. Specifically, we established a model that TCP throughput in wireless network is composed of physical bandwidth and its fluctuation elements. We also evaluated the model quantitatively with real measurement on a commercial cellular network. |
