基于非结构化P2P网络资源检索的自组织研究

Research on self-organization based on unstructured P2P network resource searching

通过自组织将非结构化P2P网络过渡到半结构化网络,改变传统P2P网络资源检索的盲目性,降低检索请求的响应延迟,减少检索时网络带宽的占用.针对非结构化网络的不稳定性,设计了易于管理和重构的三层自组织结构,优化检索请求在自组织结构中的传播;当节点退出网络时,采用了平稳的过渡方法,使自组织结构在重构过程中对网络的影响较小;在重构过程中根据节点的稳定程度选择管理节点,使整个网络保持相对稳定.

The authors have built half-structured network from unstructured P2P network using self-organization.Compared with traditional blind searching,it depresses response delay and reduces bandwidth use.They have also designed a three-layer structure which is easy to manage and reconstruct for searching request spreading.During reconstruction,the authors use smooth transition method to depress network impact,and choose stable management node to keep network relatively stable.
