Abstract
Aiming at the problem of low query efficiency and delay of Object Naming Service (ONS), an improved Chord algorithm is used in this paper. By introducing an improved Chord algorithm for information discovery service of EPC network, this paper classifies neighboring nodes into a group, stratifies all the nodes according to the different performance, and selects more powerful nodes as the super nodes to manage ordinary nodes in the same region. The results of simulation experiments show that the query hops and network delay are both reduced while query efficiency is improved to a certain extent. Improved Chord algorithm can effectively solve the problem of ONS query bottlenecks, thus the query efficiency in information discovery service of EPC network is improved.
