Research Status

1. Joint Research with Industry, “Protocol Testing-bed Design for Wireless Communication System”, Sept. 2009~Aug. 2011, Principle Investigator,

      The objective of the project is to build a testing bed to analysis the MAC and Network layers’ protocols of mobile cellular communication system, including 2G/3G/B3G.

2. Joint Research with Docomo, “Coexistent of Marco FDD with Femto TDD cells”, July 2009~July 2010, Principle Investigator,

      The objective of the project is to resolve the inter-cell interference problem among the Marco cells and Femto cells by the distributed resource allocation scheme and game theory.

3. National Natural Science Foundation of China, “Research on Relay and Cooperative Communication with Cognitive Radio”, Jan.2009-Dec.2012, Core Research Member,

      The objective of the project is to exploit the scientific issues of the relay and cooperative communication in cognitive radio scenarios.

4. Hi-tech Research and Development Program of China (National 863 Project), “Research on Wireless Communication Theory and Technology at High Carrier Spectrum”, Dec. 2008-Dec. 2010, Core Research Member,

      The objective of the project is to investigate the basic technologies of wireless transmission with high carrier frequency beyond 8GHz, and develop the L2/L3 protocols for such network.

5. Tsinghua Basic Research Foundation, “Networking Protocol for Wireless Cognitive Network”, Principle Investigator,

      In this research, Transmission Reliability based adaptive Routing (TRR) protocol for cognitive radio network is proposed. This TRR protocol takes Signal Stability Routing (SSR) protocol as a framework, using reliability of cognitive inter-node routing path as the routing selection criteria, meanwhile changes would be taken on SSR protocol’s structures and mechanisms to adapt to cognitive network routing characteristics.

6. Joint Research with INTEL, “WiMAX Beyond 802.16e: Client Mesh Networking”, July 2006 – July 2007, Principle Investigator.

      A mesh and cellular combination structure is proposed which supports direct data transmission between mobile terminals with the control of the Base Station if possible. This mesh model is easy to achieve, and could improve the system performance such as throughput and propagation delay. With the help of the BS, several key problems in pure wireless mesh network are satisfactorily solved, such as coexistence, interference and billing.

7. Joint Research with NEC, “Ad Hoc VoIP System on Wireless Mesh Networks”, Aug. 2005 – Aug 2006, Joint Principle Investigator,

      The objective of this project is to investigate the key technical challenges of the next-generation wireless mesh networks supporting real-time interactive multimedia applications. To be more specific, a distributed radio and channel allocation algorithm is designed for multi-hop ad hoc network, to enhance the performance of the network throughput with the joint optimization of ad-hoc routing protocols.
