Selection of multiple donor gauges via Graphical Lasso for estimation of daily streamflow time series
German A. Villalba, Xu Liang, Yao Liang
A fundamental challenge in estimations of daily streamflow time series at sites with incomplete records is how to effectively and efficiently select reference or donor gauges from…
Estimation of daily streamflow from multiple donor catchments with Graphical Lasso
German A. Villalba, Xu Liang, Yao Liang
A novel algorithm is introduced to improve estimations of daily streamflow time series at sites with incomplete records based on the concept of conditional independence in graphica…
Scalable Downward Routing for Wireless Sensor Networks and Internet of Things Actuation
Xiaoyang Zhong, Yao Liang
In this paper, we study the downward routing for network control/actuation in large-scale and heterogeneous wireless sensor networks (WSNs) and Internet of Things (IoT). We propose…
Compressed Sensing in Multi-Hop Large-Scale Wireless Sensor Networks Based on Routing Topology Tomography
Yimei Li, Yao Liang
Data acquisition from a multi-hop large-scale outdoor wireless sensor network (WSN) deployment for environmental monitoring is full of challenges. This is because the severe resour…
