This project represents an approach to P2P based on study of nature's
original P2P creatures. (02)

"Anthill is a framework aimed at supporting the design, development and
analysis of peer-to-peer protocols and algorithms. The goals of Anthill are
to: (i) provide an environment for simplifying the design and deployment of
new P2P systems, and (ii) provide a "testbed'' for studying and
experimenting with P2P systems in order to understand their properties and
evaluate their performance. Anthill is based on the multi-agent systems
(MAS) paradigm. A MAS is a collection of autonomous agents that can observe
their environment and perform simple local computations leading to actions
based on these observations. The behavior of an agent may be
non-deterministic and its actions may modify the agent environment as well
as the agent location within the environment. What distinguishes MAS from
other agent models is that there is no central coordination of activity.
MAS often exhibit a property called swarm intelligence whereby a collection
of simple agents of very limited individual capabilities achieves
``intelligent'' collective behavior. In this manner, they are able to solve
problems that are beyond the capabilities or knowledge of individual
agents. For example, ant colonies, which are natural instances of MAS, are
known to be capable of solving complex optimization problems including
those arising in communication networks. In our opinion, MAS can be
profitably adopted for the design of innovative peer-to-peer algorithms.
Anthill uses terminology derived from the ant colony metaphor. A P2P system
based on Anthill is composed of a network of interconnected nests. Each
nest is a peer entity capable of performing computations and hosting
resources. Nests handle requests coming from users by generating one or
more ants --- autonomous agents that travel across the nest network trying
to satisfy the request. Ants interact indirectly with each other by
modifying their environment by updating the information stored in the
visited nests. This form of indirect communication, used also by real ants,
is known as stigmergy." (04)
