Adapting Superpeer Size Using Particle Swam Optimization for Self-Organizing Superpeer Ring with Loosely Consistent DHT

A superpeer size adaptation using PSO is proposed for the self-organizing superpeer ring with loosely-consistent DHT. In the proposed scheme, all peers memorize the superpeer ratio where they or their neighbors experienced the best response time and adjust the superpeer ratio autonomously using PSO algorithm. Without tuning the optimal superpeer ratio value manually, the self-organizing superpeer ring can maintain moderately good response time in dynamic peer-to-peer systems.
