Column generation algorithms for virtual network embedding in flexi-grid optical networks
Network virtualization provides means for efficient management of network resources by embedding multiple virtual networks (VNs) to share efficiently the same substrate network. Such virtual network embedding (VNE) gives ...
Security enhancement for OFDM-PON using Brownian motion and chaos in cell
We propose a novel security enhancement technique for a physical layer secure orthogonal frequency division multiplexed passive optical network (OFDM-PON) based on three-dimensional Brownian motion and chaos in cell (3DBCC). ...
Opinion formation on multiplex scale-free networks
Most individuals, if not all, live in various social networks. The formation of opinion systems is an outcome of social interactions and information propagation occurring in such networks. We study the opinion formation ...
