We show that the relative motion among the fish yields a periodically time-varying network of social interactions that enriches visually driven social communication. The oscillations lead to the regular making and breaking of occlusions, which we term “switching.” We show that the rate of convergence to consensus (biologically, the capacity for individuals in groups to achieve effective coordinated motion) governed by the switching outperforms static alternatives, and performs as well as the less practical case of every fish sensing every other fish. We show further that the oscillations in speed yield oscillations in relative bearing between fish over a range that includes the angles previously predicted to be optimal for a fish to detect changes in heading and speed of its neighbors. To investigate systematically, we derive and analyze a dynamic model of interacting agents that move with oscillatory speed. We show that coordinated circular motion of the school leads to systematic cycling of spatial ordering of agents and possibilities for enriched spatial density of measurements of the external environment. Our results highlight the potential benefits of dynamic communication topologies in collective animal behavior, and suggest new, useful control laws for the distributed coordination of mobile robotic networks.</dcterms:abstract> <dc:language>eng</dc:language> <dc:rights>terms-of-use</dc:rights> <dc:creator>Ehrich Leonard, Naomi</dc:creator> <dc:creator>Couzin, Iain D.</dc:creator> <dcterms:isPartOf rdf:resource=""/> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dspace:hasBitstream rdf:resource=""/> <dc:date rdf:datatype="">2015-12-16T09:59:01Z</dc:date> <dspace:isPartOfCollection rdf:resource=""/> <dcterms:issued>2015</dcterms:issued> <dc:contributor>Swain, Daniel T.</dc:contributor> <dcterms:title>Coordinated Speed Oscillations in Schooling Killifish Enrich Social Communication</dcterms:title> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:contributor>Ehrich Leonard, Naomi</dc:contributor> <dc:contributor>Couzin, Iain D.</dc:contributor> </rdf:Description> </rdf:RDF>
