Abstract:
The development of algorithms for mobile sensors utilizing
"swarming'' dynamics is discussed. The phenomenon of swarming
has been observed in many biological systems. This idea entails
local interactions (communications) between agents that leads
to a global cooperative group behavior occurring on a larger
length scale than that of the local interactions. We use
this concept for the construction of "artificial swarms''
that arise in defense/industrial applications. Algorithms
have been constructed for the mine-countermeasures problem
and the environmental boundary-tracking problem. In the mine-countermeasure
problem, the goal is to visit a large number of underwater
sites for purposes of identifying potential mines. In the
environmental boundary-tracking problem, we seek an algorithm
for a vehicle to locate and track a boundary of some predefined
environmental concentration (oil, algae, etc.). In both cases,
cooperative agent interaction is shown to improve mission
reliability and efficiency. Analysis for both implementations
will be presented.
Biographical information Dan Marthaler
completed his undergraduate degree in Mathematics from the
University of Arizona. His doctoral work was done at Arizona
State University where he worked with Drs. Eric Kostelich
and Dieter Armbruster in two problems from nonlinear dynamical
systems. He recently moved from Duke Univerisy where he was
employed by Andrea Bertozzi as an Assistant Researcher in
the Center for Nonlinear and Complex Studies. Dan is currently
employed as an Assistant Researcher (by Andrea Bertozzi)
in the Applied Mathematics department at UCLA. His interests
encompass self propelled sentient particles, nonlinear dynamical
systems, and swarming.
