    A Study of the Modified KDD 99 Dataset by Using Classifier Ensembles

    Network security has been an important research area. KDD 99 dataset has been used to analyze various network security methods. However, it has been shown that this dataset has redundant data points that make the analysis bias for these data points. New modified data sets are proposed that overcome these...

    Adaptive Coding and Energy Efficient Packet Rate Transmission Over Wireless LAN Friendly VOIP

    Energy efficiency takes important in wireless communication systems where networked low-power devices relying on batteries should be able to communicate transparently. Current wireless network power management often substantially degrades performance and may increase overall energy usage when used with latency-sensitive applications. The authors propose power management that adapts its behavior...

    Concealing Encrypted Iris Templates in Images Using Quantized DCT Coefficients

    In this paper, the authors introduce a novel steganography-based approach to protect the iris data by hiding it into a digital image for personal identification purpose. Transformations are done to encrypt the biometric data before hiding. JPEG quantization blocks in diagonal sequence are investigated for exploring an efficient hiding algorithm...

    Component Identification From Existing Object Oriented System Using Hierarchical Clustering

    One of the important tasks in software engineering is software architecture modeling. High level software architecture is useful in all phases of software life cycle. Component based software architecture is beneficial as it is useful for reusing system parts represented as components. Most of the existing object-oriented systems do not...
