〖HJ*3/8〗〖WTHZ〗Abstract： 〖WT〗This paper presents a game model of

node strategies with incomplete information in P2P networks. The model

classifies node strategies to several sets according to the node types.

Based on it, the paper analyzes the transfer conditions of different

strategies in the game model with incomplete information, as well as

the betrayal of the node types. Simulation of the evolution of the game

is carried out, showing effectiveness of the proposed model.
