Spectrum compactness based defragmentation in flexible bandwidth optical networks

This paper proposes a novel Spectrum Compactness based Defragmentation scheme to maximize the profitability of defragmentation. Numerical simulation shows that there exists an optimum load region to operate defragmentation.
