We consider the routing and wavelength assignment (RWA) problem on wavelength division multiplexing (WDM) networks without wavelength conversion. When the physical network and required connections are given, RWA is the problem to select a suitable path and wavelength among the many possible choices for each connection such that no two paths using the same(More)
WDM optical networks are high speed networks and provide enormous capacity. Survivability is very important issue in these networks. Survivability requires resources for handling the failures. So, efficient resource allocation strategy is required for survivability. In this paper, we have presented two resource allocation strategies for survivability. These(More)
To stay ahead in competition, software organizations have to deliver required functionality consistently guaranteed with high quality. The quality expectations of customers at purchase time from the software is the major reason of emergent attention of software organizations to implement quality management in software development. Nowadays, use of Component(More)
A Mobile Ad hoc Network (MANET) is a temporary network of wireless mobile devices deployed without the aid of any pre-existing infrastructure or centralized administration. But this fascinating technology is studded with a number of serious challenges that need to be well catered before its successful deployment. These challenges include security issues(More)
MANET(mobile ad-hoc networks) is a type of network in which mobile nodes communicate to each other via radio waves. MANET is self configuring, infrastructure-less and robust network that's why nowadays its routing protocols become active research area. In this paper , literature survey of on-demand AODV and DSR routing protocols is to be discussed with(More)
One of the advantages of the Discrete Wavelet Transform (DWT) compared to Fourier Transform (e.g. Discrete Cosine Transform DCT) is its ability to provide both spatial and frequency localization of image energy. However, WT coefficients, like DCT coefficients, are defined by magnitude as well as sign. While algorithms exist for the coding of wavelet(More)
