Abstract

In the last half-decade, many considerable peer-to-peer protocols have been proposed. They can be grouped in few architectural models, taking into account basically two dimensions: the dispersion degree of information about shared resources (centralized, decentralized, hybrid), and the logical organization (unstructured, structured). On the other side, there is a lack of common understanding about adaptive peer-to-peer sytems. In our view, peers' internal structure may change in order to adapt to the environment, according to an adaptation plan. To formalize this approach, we propose the Adaptive Evolutionary Framework (AEF). Moreover, we apply it to the problem of sharing consumable resources, such as CPU, RAM, and disk space.
