Here is the schedule. Each speaker has been asked to take some time to generate some discussion, on top of the traditional questions from the audience.
10:00 - 10:45 : Presentation
Jalel Ben Othman (Université Paris 13) on the subject “Performance evaluation of Wireless networks MAC layer using stochastic approaches"
Summary: Wireless and mobile networks have many advantages as easy deployment, user mobility and
provides network access to users regardless to their locations. The most critical issues that arise in those
networks are on the resource allocations as the bandwidth is limited, the propagation (multi-path, fading,
distortion) and security since communications are transmitted over radio waves.
In this seminar I will present works done to improve Quality of Service in Wireless networks.
Three methods are proposed and evaluated and will be presented in this lecture.
In the first part a model based on Markov chains is presented to model the different service classes
defined in IEEE 802.16 based on strict priority. While in the second part I will present a new AC
that we have defined for IEEE 802.16 based on token bucket and have been evaluated using
Stochastic Automata Networks. Finally I will present a stochastic model
that represent the behaviour of a DoS attack in wireless networks using IEEE 802.11 standard.
10:45 - 11:30 : Presentation
Megumi Kaneko (Associate Professor at the National Institute of Informatics (NII) and at the Graduate University for Advanced Studies (Sokendai), in Tokyo)) on the subject "Prediction-based Radio Resource Allocation in Heterogeneous Small Cell Networks".
