This paper on 'COLOR IMAGE STEGANOGRAPHY IN DCT DOMAIN' portrays a new arena in steganography in color images in frequency domain or more precisely that in Discrete Cosine Transform (DCT) domain. In this paper the authors have proposed the exploration of a deft method for image-secret data-steg pass based sampling along with encryption and embedding in frequency domain with a variable bit retrieval...
We report a simple, cost-efficient fiber-optic sensor for monitoring pressure fluctuations in ON/OFF state. The working principle of the proposed sensor is based on light intensity modulation of a reflected signal when external pressure fluctuations cause coupling optical signal variation between two multimode optical fibers placed side by side in front of a plane reflecting mirror attached on a pressure-sensitive...
Ad-hoc network is extensively used to create a communication hotspot exploiting the Wi-Fi and Wi-Max technologies which give rise to a smart network that can be used in a broader perspective. Here, we design Rapidly Deployable Ad-hoc Network(RADAN) for handling state or national level crisis where the emergency communication network will be deployed rapidly that will reduce/eliminate the communication...
A natural Disaster or a catastrophe is a sudden incident which disturbs the normal conditions or equilibrium of an area both intensively and extensively by threatening human life and property where resources required for combating the scenario substantially exceeds what is locally available. In this paper we present a technique of deployment of Command and Control (C2) Network to generate an effective...
