Announcements

• 2023-06-27: We have decided to extend the deadline of Sheet 5 Task 3 by one week, the new deadline for this task is now 2023-07-02 (Sunday) at 23:59. Please note that this extension is valid only for this task and not the whole sheet.

• Like every year there are multiple students which registered a PECAS group but do not appear in our list of participants that was derived from the registrations in TVS. We do not have any means to contact such students directly because we only know the GitLab account name and don't have any names, matriculation numbers or email addresses. If this description fits you, YOU NEED TO BECOME ACTIVE. Please send an e-mail to the orga mailing list, containing the names, matriculation numbers, CS account names and e-mail addresses of all participants of your PECAS group. GitLab-participants that do not appear in our list of participants have to be removed from repositories for the reasons described above.
• 2023-04-04: The first introductory lecture took place, if you didn't attend, please consult the Orga slide set and/or consult with fellow students.

Mobility Management in the Internet, Wireless Communication Basics, Wireless Networking Technologies, Cellular/Mobile Communication Networks (voice and data communication), Ad-hoc and Sensor Networks.

Prerequisites (recommended)

We recommend existing basic knowledge on computer networks and communication systems protocols, e.g. coming from appropriate courses of your Bachelor programme. From the Uni Bonn "Bachelor Informatik" curriculum, we recommend the contents of the course BA-INF 101 "Kommunikation in Verteilten Systemem (KIVS)". All lecture slides are available in English language and may also be helpful for Master students who have not done taken this course. You can access the most recent course material here on the KIVS web page (no username/password required from within the University computer network).
