Wireless Networks and Mobile Computing

Objectives:
The main objective of this course is to provide the students with the competences required for understanding and using the communications component of an universal communications environment. Students will be provided, in particular, with the knowledge required to understand
> emerging communications networks, their computational demands,
> the classes of distributed services and applications enabled by networks, and
> the computational means required to create the new networks and the new applications.
