Clustering based Model to Provide Defense against DDoS attacks in MANETs
Abstract: AbstractSecurity of MANETs is the part of extensive issue of research in past years. MANET is liable to DDoS attacks because of its no fixed infrastructure, changing topology, open medium, cooperative and trust-based algorithms and absence of a well-defined line of defense. DDoS attack is a synchronized attack created by attackers to overflow the target network with big quantity of information in the form of packets such that the resources …

Representative Feature Selection for Efficient Clustering
Abstract: AbstractClustering is one of the widely used data mining techniques. In machine learning, it is an unsupervised learning method that needs training data to be used. The problem with clustering is that it is computationally expensive and takes more time for grouping high-dimensional data. Therefore it is necessary to reduce number of features in the high-dimensional data in order to make the search space reduced. Many techniques came into existance …

Image Segmentation by Grouping Pixels in Color and Image Space Simultaneously using DBSCAN Clustering Algorithm
Abstract: In this paper, the authors propose a technique for image segmentation by integrating the spatial connectivity and color features of pixels. Taking into account that an image can be considered as a dataset in which each pixel has a spatial location and a color value, color image segmentation can be obtained by clustering these pixels into different groups of coherent spatial connectivity and color. To discover clusters in spatial databases …
