EMOP2PVC:面向P2P网络的虚拟社区演化模型

摘要

近年来,P2P虚拟社区成为目前网络研究的热点之一.根据逻辑斯蒂克原理,从复杂系统理论的角度提出了P2P网络虚拟社区竞争与协作演化趋势进化过程的定量模型,讨论了P2P网络虚拟社区演化非平衡性、非线性和随机“涨落”等演化特性和作用机理,并给出P2P网络虚拟社区演化模型(EMOP2PVC).理论分析和仿真实验均表明所提出的模型具有较好的合理性和可行性.%Recently,the P2P network virtual community has become the focus on the network research field.This paper illuminates the self-organization characteristics of P2P network and proposes competition and coordination models of P2P network virtual community which are based on principles of logistic,and then discusses the mechanisms and characteristics of non-equilibrium, non-linear and stochastic "fluctuation" in the evolutionary process of P2P virtual community.This paper presents a new algorithm named EMOP2PVC(P2P network Virtual Community Evolution Algorithm).Theory analysis and experiment results indicate that the algorithm is reasonable and available.
