Peer-To-Peer networks have emerged as a common method for sharing large amounts of data. The main challenge in these networks is efficiently locating information distributed across the hosts/peers of the network by decentralized approach. In this paper, first the authors refer to the Chord protocol that is a distributed lookup service, and then propose a new method, called CLTChord, to optimize this protocol. In this new method, in addition to using the local finger tables for routing requests, the cache location tables are used, in which each node stores nodes which are at its close geographical range.
