Efficient access to spectrum is critical to maintain reliable and robust communication in military networks, especially for ground vehicles on the move. High mobility and frequent topology variations make spectrum management in battlefields challenging. In this paper, we present a decentralized, hierarchical approach to assign spectrum channels among vehicles in a fair and efficient manner. Making use of group mobility, we propose a low-complexity allocation scheme with minimum communication and computation overhead. Experimental results demonstrate that the proposed algorithm can reduce the overhead by 10+ fold with maintaining reasonable spectrum utilization.
Haitao (Heather) Zheng received her B.S.degree (with highest honor) from Xian Jiaotong University in July 1995, her M.S.EE and Ph.D degree in Electrical and Computer Engineering from University of Maryland, College Park, in May 1998 and July 1999, respectively. She joined wireless research lab, Bell-Labs, Lucent Technologies as a member of technical staff in August 1999, and moved to Microsoft Research Asia as a project lead and researcher, in March 2004. Since Sept. 2005, she has been an assistant professor in Computer Science Department, Univ. of California, Santa Barbara. Dr. Zheng was recently named as the 2005 MIT Technology Review Top 35 Innovators under the age of 35 for her work on cognitive radios. She received 2002 Bell Laboratories President's Gold Award from Lucent Bell-Labs, and 1998-1999 George Harhalakis Outstanding Graduate Student Award from Institute of System Research, University of Maryland, College Park. Dr. Zheng was admitted to the highly gifted class of Xi’an Jiaotong Univeristy, P.R. China at age of 15, and graduated with the highest honor. She has served as guest editors of JSAC and EURASIP special issues and TPC members of many conferences. Dr. Zheng’s research area includes wireless communications and networking and multimedia computing.
