基于网络拓朴的资源发现机制研究

Research on Resource Discovery Mechanism Based on Network Topology

分析了大型分布式网络所呈现的小世界和Power-Law等特征。在总结现有资源发现技术的基础上,基于网络拓扑结构构造了合适的网络覆盖和资源发现机制,有效地减少了查询消息的冗余发送,提高了资源发现的效率和成功率。

After analysis of the realistic network, it is found that many networks have a small world and the power-law properties. Taking advantage of these characteristics, network can be divided into different clusters according to the nodes interests. Nodes have similar interest that are organized together to create interest clusters. Because of the similar interest in cluster, the success rate of resource discovery will increase greatly. When clusters are not satisfied, then request will be transmitted to a higher degree and more similar node according to Power-Law property.
