Today, most Backscatter systems involve a large number of deployed tags to transmit large volumes of data. Therefore, how to fully utilize the channels and enhance network throughput turns to be a very important problem. To solve this problem, we present FlipTracer, a practical system that achieves highly reliable parallel decoding even in hostile channel conditions. FlipTracer is designed based on a key insight: although the collided signal is time-varying and irregular, transitions between signals’ combined states follow highly stable probabilities, which offers important clues for identifying the collided signals, and provides us with an opportunity to decode the collided signals without relying on stable signals. Our experimental results have shown that FlipTracer achieves a maximum aggregated throughput that approaches 2 Mbps, which is 6× higher than the state-of-the-art. This work appears in MOBICOM 17.
iGuard is a real-time automatic anti-theft system for smartphones, which protect smartphone from being stolen with high sensitivity and high accuracy. iGuard utilizes only the inertial sensing data from the smartphone. The basic idea behind iGuard is to distinguish different people holding a smartphone, by identifying the order of the motions during the ‘take-out’ behavior and how each motion is performed. The experimental results show that iGuard is accurate and robust in various scenarios. This work appears in INFOCOM 17.
Intelligent utilization of the spectrum is critical for ZigBee to survive through the dense wireless network environment. Our design, named Smoggy-Link, enables a ZigBee node to concurrently transmit data under the ongoing interference (such as Wi-Fi and Bluetooth). Realizing the relationship between interference and link quality, Smoggy-Link can use low-cost interference information for effective link selection and transmission schedule. The experiment results under both controlled environment and real-world environment show that Smoggy-Link has consistent improvements in both throughput and packet reception ratio under interference from various interferer types. This work appears in ICNP '16.
The low-cost crystal oscillators embedded in wire-less sensor nodes are prone to be affected by their working condition, leading to undesired variation of clock skew. To preserve synchronized clocks, nodes have to undergo frequent re-synchronization to cope with the time-varying clock skew, which in turn means excessive energy consumption. Our design, named DualSync, makes it possible to simultaneously achieve high clock accuracy and low cost by smartly utilizing of the temperature and voltage information. The experiment results demonstrate that DualSync outperforms state-of-art approaches in terms of accuracy and energy efficiency. This work appeared in INFOCOM '16.
