P2 P Network Model Based on Interest Similarity
摘要
Abstract
The low efficiency and large communication overhead are the main problems for traditional resource searching method looking for the resource in unstructured P2P network. To solve this problem,a new P2P network model based on interest similarity is given in this paper. The access spectrum similar nodes are found by node behavior and constitute a set of similar nodes. Through establishing the few remote connections among these nodes will improve the traditional unstructured P2P network resources searching performance. Using the high-frequency access node aggregation characteristic makes the work more easily when selecting and accessing the suitable spectrum similar nodes to establish the remote connection. Meanwhile,a new resource searching algorithm is designed for the model of resource re-trieval. The simulation results show that the model can improve the resources searching efficiency of unstructured P2P network,while re-ducing the information redundancy in the network.关键词
