User-aware WLAN Transmit Power Control in the Wild

no code implementations21 Feb 2023 Jonatan Krolikowski, Zied Ben Houidi, Dario Rossi

Yet each network comes with its unique distribution of users in space, calling for a power control that adapts to users' probabilities of presence, for example, placing the areas with higher interference probabilities where user density is the lowest.

Cross-network transferable neural models for WLAN interference estimation

no code implementations25 Nov 2022 Danilo Marinho Fernandes, Jonatan Krolikowski, Zied Ben Houidi, Fuxing Chen, Dario Rossi

Airtime interference is a key performance indicator for WLANs, measuring, for a given time period, the percentage of time during which a node is forced to wait for other transmissions before to transmitting or receiving.

Neural combinatorial optimization beyond the TSP: Existing architectures under-represent graph structure

no code implementations3 Jan 2022 Matteo Boffa, Zied Ben Houidi, Jonatan Krolikowski, Dario Rossi

Recent years have witnessed the promise that reinforcement learning, coupled with Graph Neural Network (GNN) architectures, could learn to solve hard combinatorial optimization problems: given raw input data and an evaluator to guide the process, the idea is to automatically learn a policy able to return feasible and high-quality outputs.

A hybrid primal heuristic for Robust Multiperiod Network Design

no code implementations22 Apr 2017 Fabio D'Andreagiovanni, Jonatan Krolikowski, Jonad Pulaj

Given the intrinsic difficulty of the problem, which proves challenging even for state-of-the art commercial solvers, we propose a hybrid primal heuristic based on the combination of ant colony optimization and an exact large neighborhood search.

A Fast Hybrid Primal Heuristic for Multiband Robust Capacitated Network Design with Multiple Time Periods

no code implementations21 Oct 2014 Fabio D'Andreagiovanni, Jonatan Krolikowski, Jonad Pulaj

We investigate the Robust Multiperiod Network Design Problem, a generalization of the Capacitated Network Design Problem (CNDP) that, besides establishing flow routing and network capacity installation as in a canonical CNDP, also considers a planning horizon made up of multiple time periods and protection against fluctuations in traffic volumes.
