Transaction execution in mobile environments needs to be flexible to support typical mobile computing characteristics, like movement, disconnections and limited resources, and also to support the variety of transactional properties that might be required by different applications. This paper proposes a solution for flexible transaction processing in mobile applications, and describes a middlewa...

In this paper, we consider a heuristic approach to reduce latency for mobile tracking in a city area. Our solution is based on the idea of parallelo-sequential paging, using mobility parameters of mobile units. Some design issues, based on specific cell layouts to get enhanced performance in terms of paging delay and call blocking, are also considered. The proposed algorithms employ breadth fir...

This work describes learning units, experiments, and infrastructure of a remote laboratory with mobile robots in tele-education. Remote experiments with real hardware are an important issue in the education of engineers and students of natural sciences. The presented infrastructure is based on JAVA applets in a server/client architecture to accommodate several self-contained learning units with...
