Effectively DecreasingtheMaintenance Overhead of
Highly Dynamic Chord System · 2008
P2Psystems arehighly dynamic innature. Nodes mayjoininorleave theP2Psystematanymoment.Frequently joining orleaving mustincrease themaintenance overhead greatly inDHT-based P2Psystem. Themainreasonofcausing thecostisthelookup costthatnodesbuild their fingers. Inthis paperweintroduce aniterative joinalgorithm forChordthatis suitable forhighlydynamicenvironments. Iterative join algorithm builds thefinger ofnodebyiterative lookup andbythe helpoffingers information ofnodesinthelookup path. Theory analysis andsimulation showthatIterative joinalgorithm decreases efficiently themaintenance overhead andimprove the lookup performance.
