—In this paper the problem of Routing and Wavelength Assignment (RWA) in optical Wavelength Division Multiplexing (WDM) networks has been addressed and a new weight based Edge Disjoint Path (EDP) algorithm for RWA has been proposed to optimize the wavelength resources in a wavelength routed WDM networks. The simulation results reveal that the network(More)
This paper proposes a new wavelength conversion algorithm in a DWDM network using online routing. The model for the algorithm has been theoretically developed and the corresponding call connection probability has been calculated. The limitation on the number of wavelength conversions has been addressed by fixing the maximum number of wavelength conversions(More)
Digital Watermarking technique is now day needs to afford more robust for any image and also safe from many type of attack. Because every day by day need of multimedia techniques progress so another hand also creating of duplication problem. In this paper literature survey many techniques discuss year by year using for resolving this problem. But according(More)
The Wavelength routed optical network employs well preconfigured optical lightpaths to carry the traffic of users to communicate in the internet at an increasingly huge data rate. The optical network requires lightpaths to maintained, which has to be optimal to route the data traffic between a source to a destination. In most cases at such high data rate,(More)
Digital Watermarking technique is now day wants to provide new vigorous for any image and also benign from many type of attack. Because every day need of multimedia techniques develop so another hand also producing of copying problem. In this paper works study many methods discuss year by year using for resolving this problematic. But rendering to my(More)
BACKGROUND Chronic diseases result in significant morbidity and costs. Although medications and lifestyle changes are effective for improving outcomes in chronic diseases, many patients do not receive these treatments, in part because of financial barriers, patient and provider-level knowledge gaps, and low patient motivation. The Assessing outcomes of(More)

— A comprehensive study of the various modulation techniques has been discussed which helps to increase data rate, to overcome dispersion effects and various non-linear effects in the fibre. Modulation formats such as OOK (On Off Keying), BPSK (Binary Phase Shift Keying), DPSK (Differential Phase Shift Keying), DP-QPSK (Dual Polarized Quadrature Phase Shift(More)
