Delivery of the required QoS in IP-over-DWDM networks would face uncertain environment capacity problems due to demand variations over different periods of network operation. Therefore, future demand uncertainties should be considered in planning DWDM transport backbones for capacity sensitive telecommunication applications with enhanced quality of service. This paper, presents a genetic algorithm...
This paper examines and analyzes the impact of correlations that exist in shadow fading between links in multihop cellular networks. Statistical moments of the total interference are derived based on two correlated shadowing models, shadowing model as functions of the spatial loss field and correlated lognormal shadowing. We apply both methods in order to evaluate performance in uplink of multihop...
This paper presents the integration of quality of service (QoS) requirements in routing and wavelength assignment (RWA) problems to design wavelength-routed dense wavelength division multiplexing (DWDM) optical networks. A genetic algorithm (GA) optimization approach is employed to solve this complex and multi-constraint problem under heavy load demand matrices employing the COST239 test bench. Simulation...
The important role of quality of service (QoS) in deployment of a resilient dense wavelength division multiplexing (DWDM) backbone for global networks requires critical design-phase planning optimisation. The design issues of resilient DWDM networks for bandwidth and delay sensitive applications of dedicated path protection are addressed. A genetic algorithm (GA) model has been developed to solve...
Adaptation of QoS in DWDM optical networks routing and the wavelength assignment (RWA) problem, known as an NP-hard problem, are addressed. The QoS constraint based routing RWA computes lightpaths for the original-destination node pair, (O, D), to meet the QoS propagation delay requirements. A heuristic algorithm based on a genetic algorithm (GA) is then developed to solve this problem. A simulation...
