Chord algorithm based on two-way routing table

Chord algorithm is a typical and relatively successful routing algorithm in the structured P2P network, but it needs to be improved in searching efficiency. By the method adding a reverse routing table for each node,the finding each hop is as close as possible the target node to reduce search times in the search process, that is, to improve the search efficiency. The analysis of examples proves that routing hop times have a certain decrease in the search process, and the search efficiency is improved.
