Simulation of communities of nodes in a wide area distributed system

The complex structure of the Web requires decentralised, adaptive mechanisms efficiently providing access to local and global capacities. To facilitate the development of such mechanisms, it seems to be reasonable to build clusters or grids of machines with similar structures and interests. In such a manner, communities of machines can be built. In a community, every machine contributes to the overall success through a division of management work and a respective collaboration. This article presents and analyses experimental results for algorithms optimising service response times in a community. We introduce a community simulation tool, which is used to experiment with optimisation algorithms. The experimentation results are presented and analysed.
