	Biography

	Xiaolong Huang received the Ph.D. degree in Electrical Engineering from the University of California, Los Angeles (UCLA), California, USA, in 2006. He received the B.Sc. and M.Phil. from Peking University and Hong Kong University of Science and Technology, in 1999 and 2001, respectively, all in Electrical Engineering. Xiaolong Huang Joined the Motorola's R&D Center in China as an internship engineer to conduct software tests in Summer 1998. He was entitled the second prize of the Challenge Cup 1998 with other three team members at Peking University for his work in the network applications development. In 2003, he joined the HITACHI's R&D Center in China as an internship researcher to design protocols for MIPv6. In January 2007, he joined NextWave Wireless, San Diego, California, USA to develop WiMAX systems. Since December 2008, he has been with the Office of the Chief Scientist, Qualcomm Inc, San Diego, California, USA. Xiaolong Huang's research interests include telecommunications and computer communications systems, mobile ad hoc networks, infrastructure wireless communications and networks, network simulations and analysis.

	Academic Experiences

	■ Hong Kong University of Science and Technology Developed a theoretical framework named as Max-Min Fairness bandwidth allocation at the MAC layer in wireless ad hoc networks to allocate max-min fair capacity for each active link. This work has been cited by more than 50 journal articles, conference proceedings and book chapters, such as “Collision Avoidance Protocols” in “Ad Hoc Networks: Technologies and Protocols” (ISBN: 0-387-22689-3). ■ University of California, Los Angeles Modeled and provided optimization methods for the activation of sensor nodes to minimize the reproduction distortion incurred during sensing and communications networking processes under communications capacity and energy resource constraints. Derived an analytical method to calculate the bit-per-joule performance in ad hoc networks with or without the formation of a mobile backbone, and subsequently analyzed the proper distance threshold level to be used for maximizing the bit-per-joule performance level for multihop mobile backbone networks. Designed an on-demand distance aware routing scheme for Mobile Backbone Networks and analyzed the proper distance threshold level to make efficient use of network-wide capacity resources.
