Dr. Xudong Wang received his B.E. in Electric Engineering and his Ph.D. in Automatic Control in 1992 and 1997, respectively, from Shanghai Jiao Tong University, Shanghai, P. R. China. In August 2003, he also received a Ph.D. in Electrical and Computer Engineering from Georgia Institute of Technology. Dr. Wang founded TeraNovi Technologies, Inc. in 2008 and have been working on the cutting-edge technologies for wireless networks, smart power systems, computer vision, and automation. He is also an affiliate faculty member with the University of Washington. Before that, he was a research engineer, a senior network architect, and then an R&D manager at Kiyon, Inc., where he led research and development in wireless mesh networking technologies. He is the creator of the pioneering single-channel and multi-channel TDMA technologies for 802.11 mesh networks. His research interests also include cognitive/software radios, cross-layer design, and communication protocols for cellular networks, mobile ad hoc networks, sensor networks, and ultra-wideband networks. He holds patents in wireless mesh networking technologies and many of his inventions have been successfully transferred to products.

Dr. Wang was the demo co-chair of the ACM International Symposium on Mobile Ad Hoc Networking and Computing (ACM MOBIHOC 2006). Currently he is an editor for Ad Hoc Networks (Elsevier) and is also a guest editor for several special issues on wireless mesh networks in IEEE Wireless Communications, Elsevier Ad Hoc Networks, and ACM/Springer Mobile Networks and Applications. He was a technical program co-chair of Wireless Internet Conference (WICON) 2007 and a general co-chair of WICON 2008. He has been a technical committee member of many international conferences and a technical reviewer for numerous international journals and conferences.

Dr. Wang is an IEEE senior member, an ACM member, and a voting member of IEEE 802.11 and 802.15 Standard Committees. He was a member of the Broadband and Wireless Networking Laboratory (BWN-LAB), and his advisor was Dr. Ian F Akyildiz.

Industrial Contributions

Xudong Wang has invented and also successfully implemented the following MAC protocols based on IEEE 802.11 technologies:

  • Distributed Single-Channel TDMA MAC for Wireless Mesh Networks Based on IEEE 802.11
  • Distributed Multi-Channel TDMA MAC for Wireless Mesh Networks Based on IEEE 802.11

These MAC protocols have integrated novel schemes of distributed TDMA scheduling, distributed channel and time slot allocation, fast channel switching, software MAC architecture, and cross-layer design. These technologies have been successfully transferred into Kiyon’s mesh point (MP) and mesh access point (MAP). They are backward compatible with existing 802.11 standards and will be compliant with the emerging IEEE 802.11s standard. Field tests of these products have demonstrated great performance in scalability and throughput.

 

Xudong Wang’s inventions also include fast roaming, multi-radio mesh networking, single-radio client access, and dynamic frequency selection, which are all building blocks of Kiyon’s MP and MAP products.

 

Currently Xudong Wang is also working on a Mesh-QoS project with an objective to simultaneously deliver VoIP, IPTV, and data traffic over wireless mesh networks. This project involves research and development efforts in multiple protocol layers including MAC, routing, transport, and mobility management.

 

He has also invented layer-2 routing with distributed MAC for UWB mesh networks, in which functions such as layer-2 routing, distributed time slot and channel allocation, virtual multi-hop networking, and rate adaptation work together as one module in the same MAC protocol.
