This strategy is developed on a geometric approach without requiring estimation of algebraic connectivity. It is originally based upon behavioral control, but upgraded by distributed node control with a mobility constraint for global network integrity preservation and distributed connectivity control with a local connectivity minimization strategy for network coverage expansion. Thanks to properties of HDC, a networked MRS is capable of achieving high performance with cooperative tasks. We have examined and evaluated our proposed method in both simulations with up to 100 simulated robots and real-world experiments with up to 14 real robots. publisher: IEEE date: 2020-03 type: Article type: PeerReviewed identifier: Pham, Duy Hung and Tran, Quang Vinh and Ngo, Trung Dung (2020) Hierarchical Distributed Control for Global Network Integrity Preservation in Multirobot Systems.
