Self-adaptive Chord risk model based on DHT for Peer-to-Peer networks
Zhijie Li · Computer Engineering and Applications Journal · 2007
This study's objective is to solve the problem that the Chord model is not appropriate for dynamic network as it brings large numbers of messages.A self-adaptive Chord based on DHT(Distribute Hash Table)is proposed.When node join or leave,it does not maintain consistency of entire network's logic topology,but only update routing table of node's predecessor and successor.Besides,nodes update their routing table when they transmit messages.Therefore logic topology of entire network tends to a consistent state.The experimental results show that self-adaptive Chord both evidently lessen messages caused by node join or leave,and basically reserve efficient search performance which is close to Chord.The conclusion indicates that model could provide a candidate solution of ad hoc P2P network with high churn rate.
