Privacy-Preserving Transactions On The Web, Sahil Behl, Leszek T. Lilien

The Hilltop Review

There is a rapid growth in the number of applications using sensitive and personal information on the World Wide Web. This growth creates an urgent need to maintain the anonymity of the participants in many web transactions and to preserve the privacy of their sensitive data during data dissemination over the web. First, maintaining the anonymity of users on the World Wide Web is essential for a number of web applications. Anonymity cannot be assured by single interested individuals or an organization but requires participation from other web nodes owned by other entities. Second, preserving the privacy of sensitive data …

Wmu Mobile For Iphone, Christopher A. Ashbay, Justuce Reule, Tim Wickey

Honors Theses

Western Michigan University does not currently have a smart phone application. WMU Mobile for iPhone was created for WMU students as a mobile source for campus news, weather information, and athletics highlights. It also provides connections to various sources of WMU media, and allows users to access GPS maps of campus buildings. The app is designed to allow for future releases which may include allowing the user to view campus events by department and search campus maps. The WMU Mobile for iPhone is accessible on the iPhone, iPod Touch, and iPad, and is available for free through the Apple App …

Leach-Sm: A Protocol For Extending Wireless Sensor Network Lifetime By Management Of Spare Nodes, Bilal Abu Bakr

Dissertations

Operational lifetime of a wireless sensor network (WSN) depends on its energy resources. Significant improvement of WSN lifetime can be achieved by adding spare sensor nodes to WSN. Spares are ready to be switched on when any primary (a node that is not a spare) exhausts its energy. A spare replacing a primary becomes a primary itself.

The LEACH-SM protocol (Low-Energy Adaptive Clustering Hierarchy with Spare Management) proposed by us is a modification of the prominent LEACH protocol. LEACH extends WSN lifetime via rotation of cluster heads but allows for inefficiencies due to redundant sensing target coverage. There are two …

Debugging Support For Message-Passing Based Concurrent Software, Mohamed Medhat Elwakil

Dissertations

Today, multi-core processors are used in all computing aspects, including embedded systems such as mobile devices. In order for software programs to benefit from the transition to multi-core processors, the programs need to be concurrent.

Recent research shows that programs developed using the message-passing model can scale better than programs developed using the shared-memory model. However, the message-passing model is not widely adopted, partly, because of the lack of debugging tools. Debugging message-passing programs is very intricate due to their inherent nondeterministic behavior; even with the same input, a program may behave differently when executed multiple times. Bugs in message-passing …
