On this computer, the command edit is configured to launch emacs. So in this context, the
file foo will be opened in emacs as illustrated by the following reduction:

Our agent agt might have even moved to a site where the command edit is not available
because no process abstraction of that name is defined. In this case the agent agt will not
be able to edit the file foo at this site and might consider moving to a nearby computer to
do so.

6. InfoStation-based mLearning system

As we have mentioned earlier that eLearning is becoming an authentic possible alternative
educational approach as the technologies regarding that area are developing so fast, and
there is a recognisable growth of a great variety of wide-band telecommunication delivery
technologies. The infostation paradigm first proposed by Frenkiel et al. [Frenkiel,1996] and
used in [Ganchev,2007] to devise an infostation-based mlearning system which allows
mobile devices such as cellular phones, laptops and personal digital assistants (PDAs) to
communicate to each other and to a number of services within a university campus. This
mLearning system provides a number of services among which are: mLecture, mTutorial,
mTest and communication services (private chat, intelligent message notification and phone
calls). This section presents the architecture of the infostation-based mLearning system and
describes the policies of the mLecture service.

6.1 mServices

This section introduces at glance each of the mServices provided by the infostation-based
mLearning system.

 AAA : in order for any user to use any mService in the system, the user device should be

registered. The AAA service (Authentication, Authorisation and Accounting) allows the
users to register their devices with the system to gain the ability of using the mLearning
services offered by the system.
