MODIFICATION OF MIMO HOST LOCATION OPTIMIZATION FOR ACTIVE ACCESS-POINT CONFIGURATION ALGORITHM IN ELASTIC WLAN SYSTEM

摘要

Previously, to improve the network perfor- mance, we proposed the multiple-input multiple-output (MIMO) host location optimization as an extension of the active AP con guration algorithm in the elastic WLAN system. However, our empirical studies de- picted that concurrent communications between mul- tiple hosts and a single AP offer different throughput features from the single communication between one host and an AP. As a result, obtained throughputs in simulations for the MIMO host location optimization are different from those in experiments. In this paper, we propose the modi cation of the MIMO host location optimization considering the effect in concurrent com- munications, where the effectiveness is veri ed through testbed experiments.
