P2P (Peer-to-Peer) network has extensive functionality in variety of fields. Accordingly, P2P users share huge amounts of data. The widespread usage of P2P systems can make it a potential truck for worms. The attractiveness of a particular P2P group can be reduced by widely spread malicious peers. Now internet community has concentrated more on its security. One of the solutions prevailing to prevent...
Noise in images is ubiquitous and extraction of relevant features from noisy images is non-trivial problems. For satisfactory results of any higher level image processing like segmentation, recognition, authentication, compression, etc image denoising is an inevitable pre-processing step. Most of the practical images have directional features, edges, curves, lines and texture singularities as high...
Existing image steganographic methods lack in the complexity, which can be utilized by the radical to decode the images and neutralize the operations. Several methods have been proposed in order to combat this. Perhaps the most efficient method is Block-based Edge Adaptive based on Least-Significant-bit Matched Revisited (LSBMR) approach. It is a famous type of steganographic methods in the spatial...
In Power system, as the load changes the terminal voltage of the generator will also change. Automatic voltage regulator plays a major role in maintaining the constancy of the voltage. Automatic voltage regulator regulates the voltage with the help of controller to maintain the voltage stability of the power system. Two degree of Freedom Controller optimized by Particle Swarm Optimization will help...
Public key Cryptography, also known as asymmetric encryption is a form of cryptosystem which uses two keys, public key and private key for encryption and decryption respectively. This type of cryptosystem helps in achieving confidentiality, authentication or both. Public key cryptography includes key exchange, digital signatures, and encryption of blocks of data. Among the public key cryptosystem...
Data gathering by leveraging Sink's mobility in large-scale Wireless Sensor Networks (wsns) has drawn substantial interest in recent years. Challenge is to collect data in wsns through optimized network performance. Current researchers focus on how to minimize the energy of sensor nodes to help improve the lifetime of the node. Identifying mobile sink's moving trajectory in advance is cumbersome process...
