AbSTRACT
This chapter proposes a bio-inspired approach for the construction of a self-organizing Grid informa-
tion system. A dissemination protocol exploits the activity of ant-inspired mobile agents to replicate
and reorganize metadata information on the basis of the characteristics of the related Grid resources.
Resource reorganization emerges from simple operations of a large number of agents, in a “swarm
intelligence” fashion. Moreover, a discovery protocol allows Grid clients to locate useful resources on
the Grid through a semi-informed approach. This chapter also describes the SO-Grid Portal, a simu-
lation portal through which registered users can simulate and analyze the ant-based protocols. This
portal can be used by researchers to perform “parameter sweep” studies, as it allows for the graphical
comparison of results obtained in previous sessions. We believe that the deployment of the SO-Grid
portal, along with the definition and discussion of the protocols presented in this chapter, can foster
the understanding and use of swarm intelligence, multi-agent and bio-inspired paradigms in the field
of distributed computing.
