This paper presents our experience in designing, implementing, testing, and applying a
general-purpose antenna extension solution with commodity Wi-Fi. The proposed solution …

We propose and experimentally evaluate a novel method that dynamically changes the
contention window of access points based on system load to improve performance in a …

Tiny IoT devices have shown their utilities in many fields. However, due to the low cost, small
form factor, and inherently restricted computation resources, these IoT devices are facing …

We show experimentally that workload-based AP-STA associations can improve system
throughput significantly. We present a predictive model that guides optimal resource …

The signal intensity based wireless terminal access mechanism is the key cause of
imbalanced load of WLAN. In the environment where users are densely packed, such as …

As our modern life is very much dependent on the Internet, measurement and management
of network reliability is critical. Understanding the health of a network via outage and failure …

In this thesis, we discuss the feasibility of using distributed antenna systems to facilitate the
deployment of IoT devices. Our approaches are inspired by Fresnel zone plates focusing …
