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.

RESEARCH POSITIONS (recruiting ad in Chinese): FOUR Research assistant positions are available (remain openning till filled), please follow application instructions to apply. Currently, I am particularly interested in applicants with background in one or more of the following (1) wireless networking and mobile computing, (2) cognitive radio and MIMO technology, (3) algorithmic method and optimization (4) RF and PCB hardware design.

Projects:
  1. NSF 1343306, EARS: Modeling and Analysis of Radar / Communications Spectrum Sharing Opportunities a three-year grant from the National Science Foundation. This research effort focuses on the impact that 4G/LTE wireless devices (e.g. cell towers and smart phones) may have on radar altimeters operating in the 4200-4400 MHz spectral band. To obtain this understanding, a significant spectrum measurement campaign will be undertaken focused on appropriate radar altimeter systems and on 4G/LTE systems.
  2. NSF 1247944, 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.
