Wireless sensor networks (WSNs) are deployed for monitoring in a range of critical domains (e.g., healthcare, military, and critical infrastructure). Accordingly, these WSNs should be resilient to attacks. The current approach to defending against malicious threats is to develop and deploy a specific defense mechanism for a specific attack. However, the problem with this traditional approach to defending sensor networks is that the solution for a jamming attack does not defend against other attacks (e.g., Sybil and selective forwarding).

Desktop web browsing is becoming more and more heavyweight due to advertising concerns, related content linking, and various media (images, video, etc.). Many people prefer the more lightweight approach offered by mobile-specific formats. The goal of this project is to offer a customizable web-viewing experience on the desktop. Using a combination of client- and server-side technology, we allow users to enter any URL and browse the site with as much or as little of the page hidden as they like.

Wireless sensor networks (WSNs) are now widely used for monitoring and controlling systems where human intervention is not desirable or possible. Connected dominating set (CDS) based topology control in WSNs is one kind of hierarchical method used to ensure sufficient coverage while reducing redundant connections in a relatively crowded network. Moreover, a minimum connected dominating set (MCDS) has become a well-known approach for constructing a virtual backbone (VB) to alleviate the broadcasting storm for efficient routing in WSNs.

Apache Pig is a platform for analyzing large datasets built on Hadoop. The goal of this project is to create a tool that allows users to harness the power of Pig to create powerful data-cleaning scripts without the steep learning curve of Pig Latin or MapReduce. A set of extensions (user-defined functions) to Pig aimed at data cleaning as well as an easy-to-operate GUI program called Piglet that allows the user to manipulate the extensions will be shown.

STEM Portal is an online learning tool. It consists of an applet to explain a concept and a short quiz to test understanding of the topic. The project has been implemented with CodeIgniter, Doctrine, dynamic Google Charts, and a MySQL database. CodeIgniter is an open-source web application framework for use in building dynamic web sites with PHP. Doctrine is an object relational mapper for PHP that sits on top of a powerful database abstraction layer.
