STGED framework outperforms baselines in predicting future network connectivity for tactical communication networks.
要約
The content introduces the Spatial-Temporal Graph Representation Learning for Tactical Networks Future State Prediction. It discusses the challenges in resource allocation in tactical ad-hoc networks and the importance of accurate prediction of future network connectivity. The STGED framework hierarchically utilizes graph-based attention mechanism, recurrent neural network, and fully-connected feed-forward network to predict future state connectivity with high accuracy. Experimental results show STGED consistently outperforms baseline models across different time steps input.
