Statistical Design for Sensor Network Deployment
Collaborator & Mentor: Jun Yang
We discussed application scenario and solutions to the three main problems: overall design
problem and adoptive design in the sensor network deployment and analysis and inference
technique based on sensor network. (for example, Bayesian decision-theoretic setup, adaptive
suppression and uncertainty analysis of simulation models)
Working Group IV Sensor Network Datasets
Research Areas
Statistical Analysis of Water Potential Data
Collaborator & Mentor: Paul Flikkema
We are interested in modeling and inference issue on water potential dataset. Based on this, we
expect various applications to joint coding, estimation and transmission censoring issues in
energy-centric wireless data gathering networks.
Statistical Modeling for Soil Moisture Dynamics
Collaborators & Mentors: Jim Clark and Alan Gelfand
We are developing statistical modeling and inference for soil moisture dynamic based Duke
forest dataset. This project includes ecological scientific issue and Bayesian inference for
spatiotemporal soil moisture process.
