Closure under Coupling of Cellular-DEVS for the Optimization of Memory Resource: Wildfire Spread Case Study
The present work aims to show one of the advantages of using the property of
closure under coupling in the DEVS specification. The advantage concerned in
this paper attempts to address the need for memory resources during the
simulation of systems by cellular-DEVS. This improvement of performance is
based on the usage of the property closure under coupling in the DEVS
formalism. With this property and taking account of the iterative behavior of
each cellular-DEVS atomic model, we provide simulation of many models
simultaneously. The method starts with the specification of the cellular-DEVS
coupled model which is then converted into its equivalent DEVS atomic model.
Thus, the goal of this conversion is to transform large quantities of atomic
models coupled together, which require huge computational resources, into one
DEVS atomic model. A case study is presented at the end of the work on modeling
and simulation of forest fire propagation using DEVS and cellular-DEVS. A
specification by cellular-DEVS of the forest fire model and its non-modular
equivalent DEVS atomic model are presented. Finally, a comparison between both
methods is presented in term of consumption of resources.Comment: This work was conducted between 2013 and 201
