With an abundance of social network data being released, the need to protect sensitive information within these networks has become an important concern of data publishers. One of privacy preserving approaches often used is anonymization. This paper focuses on the popular notion of <i>k</i>-anonymization, where <i>k</i> is the required threshold of(More)
Internet today is also a medium of sharing immeasurable amount of information for widespread Peer to Peer (P2P) environments. Various application domains such as file sharing, distributed computing and e community based applications adopted the P2P technology as underlying network structure. A fairly open structure of P2P network applications, also make(More)
As the dependency on Internet is increasing, the service providers are launching numerous web applications to facilitate the users. Due to threat of unauthorized access they want to identify their users accurately. In the same way, leakage of sensitive information makes clients aware enough to make sure whom they are dealing with. This leads to the(More)
Document clustering is used in information retrieval to organize a large collection of text documents into some meaningful clusters. k-means clustering algorithm of pratitional category, performs well on document clustering. k-means organizes a large collection of items into k clusters so that a criterion function is optimized. As it is sensitive to the(More)
There are many existing algorithms efficiently using the immense bandwidth of optical fiber switching by providing a contention free environment. These algorithms use either the hardware based or the software based approaches. Optical routing &amp; buffering and wavelength converters are often employed to provide a solution to the same. In this article, we(More)
In the study of networks, such as complex network, social network or biological network; number of different characteristics of many nodes are found common. These characteristics includes small-world property, clustering and community structure, among others. In the context of networks, community structure refers to occurrence of groups of nodes in a(More)
