Abstract :
In this paper an MRESDL dynamic model is proposed for analyzing file diffusion in a node-to-node (P2P) file-sharing network. According to the principle of the P2P file diffusion system, each node not only shares the downloaded parts of the file, but also downloads the needed parts of the file. This behavior is similar to the spreading of epidemic diseases. The well-known medical model SIR is applied and modified to simulate P2P system. There exist five types of node in the model of MRESDL, which is used to simulate the dynamic behavior of the P2P network. Model of MRESDL is proved to have the ability to simulate the behavior of the nodes in P2P and is can be used to research the influence arguments of P2P file-sharing behavior.
