In this paper, we compare the Dynamic Source Routing (DSR) protocol and our Energy Aware Dynamic Source Routing protocol (EADSR). The implementation of the routing protocols is carried out using the Click modular router infrastructure on laptops with wireless ethernet cards running Linux. We demonstrate the working of both ad hoc routing protocols through our experiments and highlight the energ...

The proliferation of mobile computing devices including laptops, personal digital assistants (PDAs), and wearable computers has created a demand for wireless personal area networks (PANs). PANs allow proximal devices to share information and resources. The mobile nature of these devices places unique requirements on PANs, such as low power consumption, frequent make-and-break connections, resou...

Power consumption is a leading concern when running applications on battery operated devices such as handhelds and laptops. This concern is heightened when accessing multimedia streams, owing to their high CPU requirement, and their realtime characteristics. Various techniques have been devised to optimize power consumption while maintaining the quality of the media presentation. Solutions rang...

Modern personal computers, including laptops, notebooks and perhaps smartphones, often have a low-resolution camera and a powerful graphic card. In this paper we present a system that uses these resources (camera and GPU) to build a low cost virtual 3D Human Interface Device. To do this, we apply an optical flow algorithm which is characterized by its high degree of parallelization. The experim...

This research explores the effect of the use of laptop computers on students’ learning experiences during lectures. Our methodology involves embedding laptops with visualization software as a learning aid during lectures. We then employ a framework of seven principles of good practice in higher education to evaluate the impact of the use of laptop computers on the learning experience of compute...

Today, computing nodes are everywhere, either visible as laptops and mobile phones or invisible as embedded devices in trains, home appliances or in the backbone of the Internet. The management of those devices becomes more and more difficult as the number of devices and the complexity of the applications increase. In order to cope with this complexity the idea of nodes with self-*1 features em...

Xgrid is the first distributed computing architecture built into a desktop operating system. It allows you to run a single job across multiple computers at once. All you need is at least one Macintosh computer running Mac OS X v10.4 or later. (Mac OS X Server is not required.) We provide explicit instructions and example code to get you started, including examples of how to distribute your comp...

The MUI framework supports composition of ad-hoc applications from services available on ad-hoc networked devices. MUI is an openended framework, relying on migrating user interfaces and standardized data formats for connecting services, allowing existing devices to be connected to new devices without needing any pre-defined knowledge of their services. We illustrate the benefits of the approac...

The Chip Multiprocessor (CMP) will be the basic building block for computer systems ranging from laptops to supercomputers. New software developments at all levels are needed to fully utilize these systems. In this work, we evaluate performance of different highperformance sparse LU factorization and triangular solution algorithms on several representative multicore machines. We include both pt...
