| description | With the wide applications of the <i>Internet of Things (IoT)</i> in <i>smart home</i> systems, <i>IEEE 802.11n Wireless Local Area Networks (WLANs)</i> have become a frequently chosen communication technology due to their adaptability and affordability. In a high-density network of devices such as the <i>smart home scenerio</i>, a host often meets interferences from other devices and unequal <i>Received Signal Strength (RSS)</i> from <i>Access Points (APs)</i>. This results in <i>throughput unfairness/insufficiency</i> problems between hosts communicating concurrently in WLAN. Previously, we have studied the <i>throughput request satisfaction method</i> to address this problem. It calculates the <i>target throughput</i> from measured single and concurrent throughputs of hosts and controls the actual throughput at this target one by applying <i>traffic shaping</i> at the AP. However, the insufficiency problem of maximizing the throughput is not solved due to interferences from other hosts. In this paper, we present an extension of the <i>throughput request satisfaction method</i> to maximize the throughput of a high-priority host under concurrent communications. It recalculates the target throughput to increase the actual throughput as much as possible while the other hosts satisfy the least throughput. For evaluations, we conduct experiments using the test-bed system with <i>Raspberry Pi</i> as the AP devices in several topologies in indoor environments. The results confirm the effectiveness of our proposal. |
