Wavelength Assignment for Dynamic Traffic in Multi-fiber WDM Networks

We propose an on-line wavelength assignment algorithm for multi-fiber WDM networks, in which lightpaths are established and released dynamically. For a given number of fibers per link and number of wavelengths per fiber, the algorithm aims to minimize the blocking probability. It may also be used to reduce the number of wavelengths required for a given tolerable blocking probability. Simulation...

Distributed Wavelength Assignment Algorithm for Optical Bursts in WDM Networks

We present a distributed wavelength assignment algorithm named Priority-based Wavelength Assignment (PWA) for the contention resolution problem in buffer-less burst optical networks without wavelength conversion capability. Simulation results show that the PWA can effectively reduce the blocking probability and increase the performance of burst optical networks compared to previous algorithms s...

Dynamic Wavelength Assignment in Cognitive Optical Network

This paper investigates the problem of wavelength assignment in dynamic wavelength reusable multicarrier distributed (WRMD) wavelength-divisionmultiplexing (WDM) networks. In WRMD network lightpath between source and destination edge nodes (ENs) are established by using multi-carrier light source (MCLS). An MCLS is a communication light source device that can generate multiple optical carriers ...

Multihop Routing and Wavelength Assignment Algorithm for Optical WDM Networks

We propose a new routing and wavelength assignment scheme that improves the blocking probability of WDM networks and offers a very good utilizat ion of the networks resources. This heuristic results in high quality of service, prioritization of the LAN networks and lower installat ion costs compared with the traditional RWA algorithms applied in WDM networks. It is based on the distributed Dijk...
