Abstract: In a super-peers-based P2P network, if super-peers fail or leave, it may bring many problems, such as resource losing, network topology changing and increasing bandwidth occupancy for re-election. To solve these problem, this paper brings up a super-peers abdicate algorithm based on user’s behavior characteristic. According to statistic characteristic of the node failure, the SPAA algorithm can forecast the node leave time and appoint next super-peer. Simulation and analysis show that the SPAA algorithm can effectively reduce the net churn by super-peer failure and reduce network traffic.
