Research
My research was supported by US NSF and NSF of China. My current research interests are mainly about the algorithm design and analysis for practical questions, including wireless ad hoc and sensor networks; protocol design in networks with selfish participants; protocol design in networks with some malicious participants, related to trusted computing; computational geometry; the properties and applications of social networks formed by social relations.

Projects:

1. EARS: Providing Predictable Service and Spectrum Access With Realtime Decision in Cognitive Multihop Wireless Networks, a three-year grant from the National Science Foundation. The objective of this project is to design real-time temporal-spatial spectrum sharing, trading and accessing schemes to provide predictable service and improve the network performances by fully exploiting the channel availability (e.g., spatial, temporal, and spectral) and quality (e.g., signal to interference plus noise ratio and data rate) diversities using cognitive radio techniques.
2. "Managing Loosely Coupled Networked Control Systems with External Disturbances", led by IIT Computer Science Professors, Xiang-Yang Li and Shangping Ren, together with two IIT Engineering faculty, Professor Paul Anderson from the Department of Civil, Architectural, and Environmental Engineering and Professor Fouad Teymour from the Department of Chemical and Biological Engineering, collaborated with the Metropolitan Water Reclamation District of Greater Chicago. This is an NSF funded CPS medium project with PI Xiang-Yang Li.
3. CitySee project: a large scale sensor networks for monitoring city environment. This is a project collaborated with Y. Liu from Tsinghua and several other faculty, supported by WuXi government and NSF of China.
4. Cognitive Radio Networks: study some fundamental performance limits on CRN, and do system implementation and verfication. This is an NSF funded project, with PI Xiang-Yang Li.
5. GreenObs for forest monitoring (collaboration with YunHao Liu from HKUST, JiZhong Zhao from Xi'An JiaoTong, Ming Gu from Tsinghua, GuoMo Zhou from Zhejiang Forestry Univ, GuoJun Dai from HangZhou DianZi, HuaDong Ma from Beijing University of Posts and Telecommunications).
   
6. OceanSense, Sensor Network for Sea Monitoring (collaboration with YunHao Liu from HKUST).
