An Ordinary Differential Equation Framework for Stability Analysis of Networks with Finite Buffers
Xinyu Wu, Dan Wu, Eytan Modiano
We consider the problem of network stability in finite-buffer systems. We observe that finite buffer may affect stability even in simplest network structure, and we propose an ordi…
Fundamental Limits of Routing Attack on Network Overload
Xinyu Wu, Eytan Modiano
We quantify the threat of network adversaries to inducing \emph{network overload} through \emph{routing attacks}, where a subset of network nodes are hijacked by an adversary. We d…
Achieving AoI Fairness in Spatially Distributed Wireless Networks: From Theory to Implementation
Nicholas Jones, Joshua Wornell, Chao Li +1
We design and implement two variants of a practical random access protocol called WiFair, based on IEEE 802.11 and designed to mitigate spatial unfairness in Age of Information (Ao…
Power Failure Cascade Prediction using Graph Neural Networks
Sathwik Chadaga, Xinyu Wu, Eytan Modiano
We consider the problem of predicting power failure cascades due to branch failures. We propose a flow-free model based on graph neural networks that predicts grid states at every…
Intervention-Assisted Policy Gradient Methods for Online Stochastic Queuing Network Optimization: Technical Report
Jerrod Wigmore, Brooke Shrader, Eytan Modiano
Deep Reinforcement Learning (DRL) offers a powerful approach to training neural network control policies for stochastic queuing networks (SQN). However, traditional DRL methods rel…
Optimal Slicing and Scheduling with Service Guarantees in Multi-Hop Wireless Networks
Nicholas Jones, Eytan Modiano
We analyze the problem of scheduling in wireless networks to meet end-to-end service guarantees. Using network slicing to decouple the queueing dynamics between flows, we show that…
