Complex software systems modelled as multi-agent systems (MAS) are characterised by activities that are generated either by agents, or by the environment in its most general acceptation—that is, environmental resources and the spatio-temporal fabric.
Modelling and engineering complex multi-agent systems (MAS) – such as pervasive, adaptive, and situated MAS – requires then to properly handle diverse classes of events: agent operations, resource events, spatio-temporal situation.
In the following, first we devise out the requirements for a software architecture for an agent-based middleware based on boundary artefacts, then we sketch a concrete architecture based on the TuCSoN middleware for MAS coordination.
