Measurements, Analysis and Modeling of Wireless Networks

Dr. Maria Papadopouli, ass. prof., University of Crete

Mattilanniemi 2, Agora building, ground floor, room Alfa: Turn right from the main lobby, follow the signs. Alfa is the corner classroom next to the side entrance.

In general, networks are extremely complex and the interaction of different layers and technologies creates many situations that cannot be foreseen during the design and testing stages of technology development. This is especially true for wireless networks, which are used for many different purposes, and which are based on a shared medium that is inherently more vulnerable than its wired counterpart. It is critical to perform measurement-based studies in order to uncover deficiencies and identify possible optimizations for better utilizing the scarce resources in wireless systems.

The seminar will first introduce fundamental concepts on wireless networks and mobile computing and focus on the IEEE802.11 and positioning. It will then introduce some basic tools for monitoring, analysis, and modeling. The second part of the seminar will present specific research topics on measurements, analysis, and modeling of wireless networks. It will analyze the traffic load, delay, packet loss, and access patterns in campus-wide wireless networks. Finally, it will evaluate the impact of network conditions on the perceived quality of VoIP over wireless networks.

PhD students can gain 2 credit points by attending the seminar, and one more credit point if there is home assignment related to the event. Prof. Tapani Ristaniemi will give instructions for the possible home assignment during the seminar.
Certificates of the credit points will be delivered on paper for the participants afterwards. Please, give the certificate to your study secretary who can put the credits into your the register.
