The paper deals with fairness issues in a slotted, single-hop, WDM (Wavelength Division Multiplexing) optical architecture, based on a folded bus topology, previously proposed as a broadband access system or as a metro network. The peculiar fairness problem arising in this folded bus based architecture is addressed and an extension of the MetaRing protocol to the WDM scenario, named Multi-MetaR...
In Wavelength Division Multiplexing based Passive Optical Network (WDM-PON), multiple wavelength used to separate Optical Network Unit (ONU). Which actually increase the capacity of PON . WDM process can be dense and ultra-dense depending on channel spacing. In this paper we compare performance of Array Waveguide Grating Demultiplexer (AWG DEMUX) and Fiber Bragg Grating based Demultiplexer (FBG...
This article compares the performance of WDM lightpath protection and IP LSP protection schemes for IP-over-WDM networks. A mathematical formulation of the maximum throughput problem is presented and analytical expressions for recovery time are derived for both schemes. The throughputs and recovery times are analyzed and compared. Results show that the IP LSP protection scheme presents higher t...
Message sequencing and channel assignment are two important issues that need to be addressed when scheduling variable-length messages in a wavelength division multiplexing (WDM) network. Channel assignment addresses the problem of choosing an appropriate data channel via which a message is transmitted to a node. This problem has been addressed extensively in the literature. On the other hand, m...
Abstract Visible light communication can be leveraged to establish a wireless link between neurons in spiking networks even when neural areas are relative motions. In electro‐optical (SNN), parallel transmission is often achieved through wavelength division multiplexing (WDM). However, WDM prohibitive certain applications due the need for multiple narrow‐band transmitters and receivers with opt...
Finite-temperature Kohn-Sham density functional theory (KS-DFT) is a widely-used method in warm dense matter (WDM) simulations and diagnostics. Unfortunately, full KS-DFT-molecular dynamics models scale unfavourably with temperature there remains uncertainty regarding the performance of existing approximate exchange-correlation (XC) functionals under WDM conditions. Of particular concern expect...
Mm Pitching moment generated by the model Inverse force measurement using a wind-driven dynamic manipulator is explored. Using system identification techniques, the WDM offers a method of measuring forces and moments on wind tunnel models during rapid, multi-axis maneuvers. Previous work has shown the measurement of dynamic stability parameters for small disturbances using the WDM. System ident...
