Robustness, imperceptibility and embedding capacity are the preliminary requirements of any watermarking technique. However, research concluded that these requirements are difficult to achieve at same time. In this paper, we review various recent robust and imperceptible watermarking methods in spatial and transform domain. Further, the paper introduces elementary concepts of digital watermarking,...
Software defined networking[1][9] has brought a rapid change in networking industry by providing programma-bility and abstraction. it also enables centralization of control in infrastructure. In this paper, we describe the results of our experiment to determine the performance of SDN by simulating Open vSwitch under conditions of congestion. We did experiments on MININET by creating four compute nodes...
Ability to move confidently is critical in maximizing independence, regardless of age and with or without existence of other disabilities. Orientation and mobility helps both children and adults to develop and master the concepts and skills which are necessary to move safely and efficiently within their world with confidence. Mobility for the visually impaired is always a great problem. With over...
The next-generation wireless systems are required to have high voice quality as compared to current cellular Mobile radio standards and provide high bit rate data services. The fundamental phenomenon which makes reliable wireless transmission difficult is time-varying multipath fading. In most scattering environments; antenna diversity is a practical, effective and, a widely applied technique for...
