The idea of an ad hoc network is a new pattern that allows mobile hosts (nodes) to converse without relying on a predefined communications to keep the network connected. Most nodes are implicit to be mobile and communication is implicit to be wireless. Ad-hoc networks are collaborative in the sense that each node is assumed to relay packets for other nodes… (More)
In this paper, a state feedback controller is designed for a non-linear system using a technique in which, the fuzzy model consists of a set of linear fuzzy local models, combined to get overall fuzzy inference mechanism. This approach utilizes a certain type of fuzzy systems that are based on Takagi-Sugeno (T-S) fuzzy models to approximate nonlinear… (More)
In this paper, a robust substitution technique to implement audio steganography is proposed. The technique resolves the various inherent problems in using traditional substitution techniques. It improves the data hiding capacity while being robust to various intentional as well as unintentional attacks.
