Proposal and Evaluation of Priority Control Method on Per-Flow Basis Based on Bandwidth Utilization to Keep Response Time Within a Certain Threshold

Abstract (in Japanese) (See Japanese page) 
(in English) Multiple data flows sharing limited bandwidth cause communication delay in communication networks. In particular it is important to deal with such a problem in the wireless LAN environments, since many terminals associate with the same access point within limited time span. In this paper, a method to increase the number of flows within response time threshold in congested wireless LAN is proposed. The method controls flow priority by calculating the bandwidth utilization ratio required to complete the download within certain time threshold. The ratio value is obtained through monitoring the transmitted data and elapsed time of transmission. In regular environment, where priority method is not applied, the ratio of flows completing the transmission within the threshold is below 50% of the total number of flows. According to the QualNet simulation results, the proposed priority method can raise this ratio to more than 80%.
