Recent advances in wireless networking technology and the exponential development of semiconductor technology have engendered a new paradigm of computing, called personal mobile computing or ubiquitous computing. This offers a vision of the future with a much richer and more exciting set of architecture research challenges than extrapolations of the current desktop architectures. In particular,...

We consider a certain class of parallel program segments in which the order of messages sent affects the completion time. We give characterization of these parallel program segments and propose a solution to minimize the completion time. With a sample parallel program, we experimentally evaluate the effect of the solution on a PC cluster.

Mobile computing devices, which are commonly known as either personal digital assistants (PDA) or personal information managers (PIM), are an emerging technology that has the potential to be very useful in specific areas of computing. One area in which mobile computing devices are gaining favor is in data collection, especially in places where larger computers are impractical. While the use of ...

Astract The remote distribution of contemporary activities has direct implications for the mobility of humans and associated actions. Remote distribution inherently entails parameters such as the mobility of individuals, artefacts, tasks and information; and potential conflicts between objective and personal motives of individuals. The interactions of these parameters bear directly on the range...

in order to improve the level of intelligence, availability, being on demand, convenience, information and humanization of rural public transportation systems, they are more willing to use modern information and communicative technologies. in addition to management services, intelligent transportation systems can provide passengers, drivers, travel agencies and other institutions with other ser...

Consumers require personal firewalls that are highly secure, easy to use, configurable and up­to­date with the latest signatures to detect malicious network activity. Robustness tests were performed on a selection of the ten most popular firewalls by market share. The test system used was a vanilla installation of Windows XP with SP2 and all the most recent updates and patches. Each firewall wa...

s Cloud computing moved away from personal computers and the individual enterprise application server to services provided by the cloud of computers. The emergence of cloud computing has made a tremendous impact on the Information Technology (IT) industry over the past few years. Currently IT industry needs Cloud computing services to provide best opportunities to real world. Cloud computing is...
