Wireless sensor networks are the ultimate technology for communication that allows network nodes to communicate without the need for a fixed infrastructure and wires. They use electromagnetic waves, as the information transmission.The development of network technologies has prompted sensor folks to consider alternatives that reduce costs and complexity and(More)
Recent years showed a wide range of applications in Wireless Sensor Networks (WSN). For a WSN, Topology Control is crucial to obtain an energy efficient network without affecting the connectivity and other properties. In this paper the sequence of strategies carried out to obtain a better scheme for a topology control in terms of energy is discussed. An(More)
Digital mammography is the most widely used diagnostic technique for detecting breast cancer. Major challenge lies in developing an efficient image segmentation technique to extract the tumour to its original size and to remove the undesirable regions completely. In this paper, a hybrid image segmentation technique by combining ability of Hough transform to(More)

The role of internet became a non replaceable one in our day to day life. Internet users also face various security threats such as eavesdropping and unauthorized access through intrusion. Internet users need to be protected and provided privacy. Network security and image encryption has become important and high profile issues. Various cryptographic(More)
Wireless Sensor Network (WSN) is widely used in recent years for the applications where human intervention is impossible. In case of nuclear power plant if any small delay occurs for data forwarding due to any node failure may results in severe disaster. Hence effective Topology Control is required to obtain an energy efficient sensor network even if any(More)
