Biography

Xinxin Liu is a Ph.D. student in Computer & Information Science & Engineering Department of University of Florida. She got her B.S. degree from Jilin University in 2006, and Master degree from Oklahoma State University in 2010. She is now working in the field of wireless sensor networks, cyber-physical systems, and mobile social networks under the supervision of Dr. Xiaolin (Andy) Li.

Research Xinxin Liu's research interests include Sensor Networks, Cyber-Physical Systems, and Mobile Social Networks. She is currently working on building a cyber-physical experiment platforms, designing energy efficient routing and data gathering algorithms, and investigating the privacy issues in mobile social networks.

Projects During my Ph.D. study, I have been involved with many research projects that are related to different aspects of sensor networks, cyber-physical systems, etc.

OKGems (GENI): A GENI-Federated Cyber-Physical System with Multi-Modalities
OKGems is a Cyber-Physical System that integrates multi-modality resources (sensors, robots, fitPCs, and Linux machines) into the NSF funded GENI project. OKGems is part of the GemsCloud project of our laboratory, which aims at forming a cloud of sensors, actuators, networks, and people.
- URL: http://okgems.ece.ufl.edu
- Responsibility: Integrate wireless sensor networks and robots to GENI; Build up our TinyHive virtual machine based network platform
- Results: OKGems system has been implemented and functional. System details are summarized in technical report and papers.
PAGrid (NSF): Precision Agriculture Sensor Grid System
By leveraging emerging technologies: sensor networks, grid computing, autonomic computing, and mobile robots, this project targets at exploiting the spatial and temporal variability of soil and crop growth factors, in order to improve agriculture management strategies.
- URL: http://www.s3lab.ece.ufl.edu/projects/ASGrid/PAGrid.html
- Responsibility: Sensor network algorithm design, implementation, and team leader
- Results: Energy efficient data collections algorithms; correlated data reporting strategy for prolonged network lifetime; automatic data sensing program implementation.
TinyHive: a Lightweight virtual machine for sensors
TinyHive virtual machine project aims at implementing a lightweight, energy efficient, multitasking virtual machine that can be running on top of TinyOS-2.x in a sensor mote.
- URL: http://okgems.ece.ufl.edu/TinyHive.html
- Responsibility: System design, basic instruction implementation, and team leader
- Results: Basic system functionalities have been implemented and tested.
MagicLink: a middleware for seamlessly weaving multi-site sensor networks
Large-scale sensor network testbeds are rarely available for researchers to test and validate their design. We address this problem by utilizing heterogeneous sensor resources at multiple geographically distributed sites, and seamlessly weaving them together by virtualizing the radio links among them.
- URL:http://okgems.ece.ufl.edu
- Responsibility: System design and implementation, virtual link modeling
- Results: The MagicLink system has been implemented and validated. Findings are summarized both in technical report and papers.
