Routing, Modulation Level, Spectrum and Multiwavelength Transponder Assignment in IP-over-EON – Integer Linear Programming and Genetic Algorithm Approaches

CLEI Electronic Journal
Elastic Optical Networks (EONs) represent a high-spectral-efficiency paradigm for accommodating heterogeneous traffic demands. However, EONs impose stringent physicallayer operational constraints, including spectrum non-overlapping, contiguity, and ...

Stability and assignment of spectrum in systems with discrete time lags

Discrete Dynamics in Nature and Society, 2006
The asymptotic stability with a prescribed degree of time delayed systems subject to multiple bounded discrete delays has received important attention in the last years.

Spectrum Planning and Network Design Quality Assessment: A Relative Surplus Bandwidth Framework With Network Design Index

IEEE Access
Spectrum assignment by national regulatory authorities (NRAs) must distinguish genuine capacity shortage from apparent shortage caused by inefficient network deployment, yet conventional methodologies (ITU-R M.1768-1, 3GPP) quantify demand without ...

Synchrotron-based infrared spectroscopy of formic acid: Confirmation of the reassignment of Fermi-coupled 8 μm states

AIP Advances, 2019
The empirically derived assignment of the strongly interacting 51 and 92 vibrational states of trans-HCOOH has recently been reassigned on the basis of anharmonic frequency calculations, and this, in turn, affects the assignment of many higher energy ...

ZAP: a distributed channel assignment algorithm for cognitive radio networks

EURASIP Journal on Wireless Communications and Networking, 2011
We propose ZAP, an algorithm for the distributed channel assignment in cognitive radio (CR) networks. CRs are capable of identifying underutilized licensed bands of the spectrum, allowing their reuse by secondary users without interfering with primary ...

Flexible Spectrum Assignment for Local Wireless Networks

, 2015
In this dissertation, we consider the problem of assigning spectrum to wireless local-area networks (WLANs). In line with recent IEEE 802.11 amendments and newer hardware capabilities, we consider situations where wireless nodes have the ability to adapt not only their channel center-frequency but also their channel width.

Effective and fair cognitive terminal assignment scheme for cooperative spectrum sensing

Dianxin kexue
Cooperative spectrum sensing is regarded as the foundation and a key stage of cognitive radio networks. The node allocation strategy during the spectrum detection process was directly determined by the results of joint spectrum sensing.
