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)
Recently, the mobile devices are equipped with various wireless interfaces in heterogeneous environments which combine a large number of radio access technologies. The evolution of these technologies will allow users to benefit simultaneously from these radio access technologies. So that the most important challenge is how to choose a most suitable network(More)
