A basic study on a robust P2P network distributed construction method

Abstract

A P2P network has a problem: it is vulnerable to attacks on hub nodes. To solve this problem, a bimodal degree network has been studied that is robust to both hub node attacks and node departures. However, the bimodal degree network construction method in the conventional studies may construct a vulnerable network. Therefore, we propose the distributed method to construct a robust bimodal degree network and show the effectiveness of our method by computer simulations.
