Exponential Backoff: Meta-Stability and Implicit Admission Control
Richard Combes, Fabien Mathieu, Thomas Bonald
We analyze exponential backoff, an algorithm used to share a single communication channel in a distributed manner between several users, in a similar way as many networking standar…
Hierarchical Beamforming: Resource Allocation, Fairness and Flow Level Performance
Julien Floquet, Richard Combes, Zwi Altman
We consider hierarchical beamforming in wireless networks. For a given population of flows, we propose computationally efficient algorithms for fair rate allocation including propo…
Multipath streaming: fundamental limits and efficient algorithms
Richard Combes, Habib Sidi, Salah-Eddine Elayoubi
We investigate streaming over multiple links. A file is split into small units called chunks that may be requested on the various links according to some policy, and received after…
Distributed coordination of self-organizing mechanisms in communication networks
Abdoulaye Tall, Richard Combes, Zwi Altman +1
The fast development of the Self-Organizing Network (SON) technology in mobile networks renders the problem of coordinating SON functionalities operating simultaneously critical. S…
Optimal Rate Sampling in 802.11 Systems
Richard Combes, Alexandre Proutiere, Donggyu Yun +2
In 802.11 systems, Rate Adaptation (RA) is a fundamental mechanism allowing transmitters to adapt the coding and modulation scheme as well as the MIMO transmission mode to the radi…
The association problem in wireless networks: a Policy Gradient Reinforcement Learning approach
Richard Combes, Ilham El Bouloumi, Stephane Senecal +1
The purpose of this paper is to develop a self-optimized association algorithm based on PGRL (Policy Gradient Reinforcement Learning), which is both scalable, stable and robust. Th…
