アブストラクト
  In this paper, we provide a generalized file replication scheme with storage load balancing function in unstructured P2P file-sharing networks. The generalized file replication scheme is expressed as a weighted mixture of the ideas introduced in the existing schemes. As a result of mathematical analysis, we show that the system behavior realized by the generalized file replication scheme can be described with a thermal diffusion equation composed of heat, reaction and diffusion terms of which weights are controlled by using a parameter of the mixing rate. Here, the heat term represents a function to enhance file search performance by making replicas on the specific peers. The reaction term represents a function to avoid concentrations of storage loads on the specific peers. The diffusion term represents a function to balance storage loads among peers. The simulation results show that the generalized file replication scheme enables us to control the trade-off between search and storage load balancing performances widely and intuitively by controlling the parameter of the mixing rate. In addition, the simulation results show that the generalized file replication scheme can adapt to dynamic P2P file-sharing environments.
