Digital watermarking is a technique which allows an individual to add hidden copyright notices or other verification messages to digital audio, video, or image signals and documents. Watermarking can be done by using least significant bit (LSB), singular value decomposition (SVD), Discrete Fourier Transform (DFT), Discrete cosine transform (DCT) and(More)
Intensity transformation function based on information extracted from image intensity histogram play a basic role in image processing, in areas such as enhancement. Histogram equalization (HE) is a conventional method for image contract enhancement. Histogram equalization improved the contrast of image by changing the intensity level of the pixel based on(More)
The explosive growth of multimedia data and real time applications have put unexpected load on network and have increased congestion in network, which occurs due to flooding of packets to intermediate node and increase in aggregate demand as compared to the accessible capacity of the resources. In mobile adhoc networks (MANETs) congestion, leads to packet(More)
Various techniques have been developed in attempt to minimize congestion in uniformly distributed networks. In this paper, a new algorithm, load balanced congestion adaptive routing (LBCAR) algorithm has been proposed for randomly distributed networks in which two metrics: traffic load density and life time associated with a routing path, have been used to(More)
Optimizing the single FPGA board resource as a simulator in a multi user environment regardless of the physical distance improved by TCP/IP. It is important step for IP and system development to use FPGA and IP core to design and improve flow of multi user data in a high speed communication internet environment and optimal utilization of available(More)
Now a days we are trying to improve through put and efficiency of existing MAC protocols used, suffering from different problem like Request to send and clear to send message propagation, and channel chapter effect or Unfairness due to using Binary Exponential Backoff algorithm, effect of noise in communication path, but it may be Possible to cause an(More)
