The paper presents a data-driven approach to predict the optimal topology of an ad-hoc robot network. The key highlights are:
The general topology prediction problem for ad-hoc robot networks is transformed into a set of simpler multi-class classification problems using a divide-and-conquer strategy. This allows efficient learning of the complex topological information.
The topology is partitioned into a backbone cycle and a branch set, which are efficiently encoded as integer vectors. This preserves the topological correlations between robots without using complex graph data structures.
The proposed learning model, called OpTopNET, successfully predicts the results of an algorithm that generates optimal topologies based on a set of complex nonlinear optimality criteria. This demonstrates the model's capacity to learn diverse optimality templates.
The paper first develops an algorithm to compute the optimal topology of a robot network based on criteria like maximizing connectivity, reliability, and structural distribution of links. It then generates a dataset of robot configurations and their corresponding optimal topologies.
OpTopNET is then synthesized as a network of stacked ensembles of multi-class classifiers, where each ensemble predicts the optimal topology for one robot in the network. The model is shown to outperform the state-of-the-art graph neural network approach in terms of accuracy and F1 score.
