IEEE conference awards 'best student paper' to group from Stevens

Paper addresses the Federal Communications Commission's spectrum policy reform

Stevens Institute of Technology

The paper, "Real-Time Secondary Spectrum Sharing with Quality of Service Provisioning," written by a group from Stevens Institute of Technology's Multimedia System, Networking and Communications (MSyNC) Lab in the Electrical and Computer Engineering department, was awarded the Best Student Paper Award at the IEEE Consumer Communications and Networking Conference (CCNC), 2006. The paper's contributors are Yiping Xing and Chetan N. Mathur, doctoral students; M.A. Haleem, a postdoctoral researcher; R. Chandramouli, Associate Professor; and K.P. Subbalakshmi, Assistant Professor.

The award committee included leading experts from industry and academia who selected the paper as the best student paper from among 220 accepted papers.

The paper deals with quality of service (QoS) issues in secondary spectrum access subject to an interference temperature constraint, in a dynamic spectrum access wireless network. This is cast as a non-linear optimization problem, and solved. When not all the secondary links can be supported with their QoS requirement, a reduced-complexity searching algorithm is proposed to find the optimal subset of links. The paper also considers a game-theoretic perspective of this problem, proving that a Nash equilibrium solution exits.

"The idea we propose addresses the FCC's spectrum policy reform. This idea is applicable to state-of-the-art technology called software-defined radio or cognitive radio," said Chandramouli.

"In the future, these software-defined radio/wireless devices are expected to become prevalent and use the wireless spectrum more efficiently due to the spectrum policy reform. Our research proposes ideas on how efficiently to use the wireless spectrum, taking an economic perspective," said Subbalakshmi.
