The computational infrastructure for information technology will be
composed of a huge number of highly heterogeneous devices connected by
different network technologies, where a great number of services and
resources will be available to users. A key point of this
infrastructure is mobility. The user will no longer be restricted to
fixed points of access and, using different devices, will be able to
access services and resources. In addition, he(she) will be able to
discover and interact with new entities as he(she) moves around.
This computing environment will be highly dynamic. New services and resources
will be frequently included, removed, reconfigured, and moved
from one place to another. Users will be moving and the communication
and coordination between all these components utilize a
highly heterogenous network. In these ever changing environments,
it will not be possible to use static software configurations and still obtain
optimal performance.
The software will have to be as dynamic as the computational environment
it is inserted. This can only be achieved through adaptation.
In order to provide a seamless environment for users, applications
and systems must adapt themselves as mobility, variations in resources
availability, and other environmental changes take place.
