The main reason of causing the cost in p2p system is the maintenance cost that nodes build their routing information. In a large-scale system or a dynamic environment, p2p system generates considerable maintenance workload, which not only increase the bandwidth consumption but also affect the routing efficiency. So we present here a new Hierarchy_based maintenance method to minimize the maintenance cost which combines the hierarchical DHT algorithm with a peer proximity mechanism. The analysis results show our design can significantly decrease maintenance cost and improve scalability of the P2P system.
