The purpose of this study was to integrate mobile communication technologies and a global positioning system (GPS) to construct an instant, convenient report of the mobile network service system named the Mobile Traffic Violation Reporting System (MTVRS), to improve learners’ traffic violation reflection level. Data were collected using a ‘‘usefulness of mobile learning systems” questionnaire a...

Mobile computing systems are made up of different components among which Mobile Support Stations (MSSs) play a key role. This paper proposes an efficient MSS-based non-blocking coordinated checkpointing scheme for mobile computing environment. In the scheme suggested nearly all aspects of checkpointing and their related overheads are forwarded to the MSSs and as a result the workload of Mobile ...

Although location based applications have been gaining popularity, most positioning devices do not work when in an indoor environment, hindering the development of indoor location based applications. In this paper we propose a technique, based on the detection of footsteps, and the direction in which they were taken by the user, to be able to calculate the position of the user inside a building...
