Abstract: A gossip-based adaptive membership protocol which is oriented to dynamic heterogeneous P2P was put forward. This protocol could dynamically adjust node degree according to node capability, and thus the node degree could be matched with the node capability, and then increasing the resource utilization and load balance. The basic operations of the protocol include: node joining, node exit, node failure restore, and node capability aggregation. The experimental results show that the proposed protocol which adapted to the node capability has higher resource utilization than the not-adapted.
