Distributed graph coloring in wireless ad hoc networks: a light-weight algorithm based on Japanese tree frogs' calling behaviour
(IEEE, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialGraph coloring concerns the problem of assigning colors to the nodes of a graph such that adjacent nodes do not share the same color. In this paper we deal with the problem of finding valid colorings of graphs in a distributed ... -
Distributed locomotion of 2-D lattice-based modular robotic systems
(Universitat Politècnica de Catalunya, 2019-07)
Treball Final de Grau
