Abstract

Aiming at the system instability of Chord which is caused by the heterogeneity of nodes in model, this paper proposes a Double Deck P2P System based on Chord (DDChord). It considers the actual processing capacity of nodes. In every group, a super-node manages the ordinary-nodes to improve system stability. To solve the routing detour which caused by DHT technical, the system proposes search algorithm which is based on topology-aware. Experimental results show that the search algorithm can reduce the query delay and improve the efficiency of query.
