- Abstract
- We address the problem of routing in wireless interference networks, where overlapping routes across multiple data flows cause interference and degrade link capacities. The objective is to design a multi-flow transmission strategy that maximizes overall network utility while accounting for dynamic interference patterns. While a range of classical and learning-based routing algorithms have been proposed, recent deep learning approaches are particularly promising due to their ability to generalize and adapt to complex network dynamics. However, most such methods still overlook the impact of wireless interference and rely on infrequent route updates to reduce computational and communication overhead. This introduces a fundamental challenge: achieving high spectral efficiency and adaptability without incurring the prohibitive cost of frequent, network-wide recomputation. In this paper, we address this challenge by developing a novel algorithm, dubbed Deep Predictive Interference-Aware Routing (DPIR), that integrates a graph neural network (GNN) with a deep reinforcement learning (DRL) agent to overcome these limitations. DPIR predicts network dynamics between routing updates and proactively determines routing schedules in advance. The GNN-based agent produces per-timestep routing decisions that are interference-aware and forward-looking. Extensive simulations over dense wireless topologies demonstrate the superiority of DPIR compared to existing routing approaches, showing consistent improvements in both throughput and packet delay. The algorithm’s robustness across varying traffic loads and network structures highlights its potential for deployment in next-generation wireless systems, including 5G and beyond.
