An Efficient Chord System Based on Super-peer

Chord is a successful structured P2P routing algorithm,but the heterogeneity of peers affects the efficiency of the system.And it brings system shaking because of a part of the peers in the network joining and leaving frequently.It's also a disadvantage that structured systems don't provide mutual anonymity.Taking advantage of the heterogeneity of capabilities across peers,we propose new Chord routing algorithm based on Super-Peer,not only to improve the efficiency of system,but also to deal with system shaking efficiently,at the same time,it could provide mutual anonymity.
