Tracking the Best Beam for a Mobile User via Bayesian Optimization
Lorenzo Maggi, Ryo Koblitz, Qiping Zhu +1
The standard beam management procedure in 5G requires the user equipment (UE) to periodically measure the received signal reference power (RSRP) on each of a set of beams proposed…
Energy savings under performance constraints via carrier shutdown with Bayesian learning
Lorenzo Maggi, Claudiu Mihailescu, Qike Cao +9
By shutting down frequency carriers, the power consumed by a base station can be considerably reduced. However, this typically comes with traffic performance degradation, as the co…
Bayesian and Multi-Armed Contextual Meta-Optimization for Efficient Wireless Radio Resource Management
Yunchuan Zhang, Osvaldo Simeone, Sharu Theresa Jose +2
Optimal resource allocation in modern communication networks calls for the optimization of objective functions that are only accessible via costly separate evaluations for each can…
Learning Algorithms for Regenerative Stopping Problems with Applications to Shipping Consolidation in Logistics
Kishor Jothimurugan, Matthew Andrews, Jeongran Lee +1
We study regenerative stopping problems in which the system starts anew whenever the controller decides to stop and the long-term average cost is to be minimized. Traditional model…
Bayesian Optimization for Radio Resource Management: Open Loop Power Control
Lorenzo Maggi, Alvaro Valcarce Rial, Jakob Hoydis
We provide the reader with an accessible yet rigorous introduction to Bayesian optimisation with Gaussian processes (BOGP) for the purpose of solving a wide variety of radio resour…
Multi-Path Alpha-Fair Resource Allocation at Scale in Distributed Software Defined Networks
Zaid Allybokus, Konstantin Avrachenkov, Jérémie Leguay +1
The performance of computer networks relies on how bandwidth is shared among different flows. Fair resource allocation is a challenging problem particularly when the flows evolve o…
Lower Bounds for the Fair Resource Allocation Problem
Zaid Allybokus, Konstantin Avrachenkov, Jérémie Leguay +1
The -fair resource allocation problem has received remarkable attention and has been studied in numerous application fields. Several algorithms have been proposed in the context…
Real-Time Fair Resource Allocation in Distributed Software Defined Networks
Zaid Allybokus, Konstantin Avrachenkov, Jérémie Leguay +1
The performance of computer networks relies on how bandwidth is shared among different flows. Fair resource allocation is a challenging problem particularly when the flows evolve o…
Virtual Function Placement for Service Chaining with Partial Orders and Anti-Affinity Rules
Zaid Allybokus, Nancy Perrot, Jérémie Leguay +2
Software Defined Networking and Network Function Virtualization are two paradigms that offer flexible software-based network management. Service providers are instantiating Virtual…
Overlay Routing for Fast Video Transfers in CDN
Paolo Medagliani, Stefano Paris, Jérémie Leguay +3
Content Delivery Networks (CDN) are witnessing the outburst of video streaming (e.g., personal live streaming or Video-on-Demand) where the video content, produced or accessed by m…
Online and Global Network Optimization: Towards the Next-Generation of Routing Platforms
Jérémie Leguay, Moez Draief, Symeon Chouvardas +4
The computation power of SDN controllers fosters the development of a new generation of control plane that uses compute-intensive operations to automate and optimize the network co…
Adapting Caching to Audience Retention Rate: Which Video Chunk to Store?
Lorenzo Maggi, Lazaros Gkatzikis, Georgios Paschos +1
Rarely do users watch online contents entirely. We study how to take this into account to improve the performance of cache systems for video-on-demand and video-sharing platforms i…
Not Always Sparse: Flooding Time in Partially Connected Mobile Ad Hoc Networks
Lorenzo Maggi, Francesco De Pellegrini
In this paper we study mobile ad hoc wireless networks using the notion of evolving connectivity graphs. In such systems, the connectivity changes over time due to the intermittent…
