In this paper, we propose a two-tiered Distributed Hash Table (DHT) based overlay for an implementation of publish/subscribe. In this overlay, upper tier consists of stable nodes with more resources whereas lower tier contains less stable nodes with limited resources. In our design, all nodes are required to join at lower tier and nodes with better uptime(More)
This paper presents text and data mining in tandem to detect the phishing email. The study employs Multilayer Perceptron (MLP), Decision Trees (DT), Support Vector Machine (SVM), Group Method of Data Handling (GMDH), Probabilistic Neural Net (PNN), Genetic Programming (GP) and Logistic Regression (LR) for classification. A dataset of 2500 phishing and non(More)
Publish-subscribe communication paradigm is an attractive alternative for MANET because of its anonymous, asynchronous and decoupled behavior. A broker is a dominant component of this paradigm and its design is non-trivial in MANET due to unpredictable mobility of nodes. In this paper, we present an algorithm to establish a reconfigurable, distributed(More)
Several design alternatives have been advocated for content-based publish subscribe communication infrastructure over structured peer to peer networks. These efforts have contributed significantly towards efficient implementations of subscription specification, installation of publications and subscriptions and notification delivery. There are some design(More)
In last few years, cloud computing has emerged as a popular alternative to satisfy the computing requirement of users. To support large number of users which is increasing very fast, the cloud service providers are forced to deploy more number of machines continuously. On the other hand, it has been observed that there are large number of machines(More)
