Evolutionary creation of linkages between information sources in P2P networks

The present paper describes a mechanism for evolutionarily creating linkages of information sources in a P2P network that are useful for both information publishers and information users. The proposed mechanism relies on interactions among information publishers, information users, and a P2P network. In order to enhance the value of their own information sources, information publishers propose new linkages of information sources that indicate information sources with which they would like to have their own information sources co-occur. The information users evaluate the linkages proposed by the information publishers. The network evolutionarily reconstructs the topological structures of the P2P network based on the fitness obtained from the users. Simulation results suggest that it is possible to find more information sources that users desire using the topological structures reconstructed by the proposed mechanism, as compared to the use of non-reconstructed topological structures.
