Outline of Final Research Achievements

Since the number of smart devices is rapidly increasing, they concentrate on a WLAN, thereby causing significant congestion. The channel resource is physically limited in WLAN so that it is necessary to prioritize a part of communication. So far, many studies focus on prioritization of communication but limited to audio or video communication, which only require packet level quality of service. In this paper, we focus on the quality of service for traffic on web browsing. Specifically, an AP estimates the remaining time until finishing to load a web page and then prioritizes the packet transmission toward a client according to the estimation result. As a result, comparing the existing method, the proposed method increase the number of flows that satisfies the requirement of quality of service by 24 percents.
