Modeling Self-Expression by holons

Finding the right instruments for increasing the level of adaptivity in ensembles of autonomic components is a challenging task, since these ensembles (as large set of computational units) are often located in non-deterministic scenarios in which stopping a system for further tuning is unfeasible. In this paper, we propose an approach to model and enable the capability of adopting different collaboration patterns in ensembles of autonomic components inserted in open and non-deterministic environments by taking inspiration from the holonic organisation of multi agent systems and Self-Expression; the latter one is defined as the property of a distributed system to change its collaboration pattern during run time executions of tasks in unknown situations. Ensembles able to deploy Self-Expression show a higher level of adaptation and the concept of Self-Expression can be easily exploited through a Self-Repeating structure like a hierarchy of holons.
