Efficient Range Queries and Fast Lookup Services for Scalable P2P Networks

Abstract

In this paper we propose a Peer-To-Peer (P2P) architecture using a tree based indexing scheme which allows for efficient lookup and range query services on documents in the network. We also present a basic load balancing technique by assigning a new node that joins the network to a heavily loaded area to take on some of load of its peers. Given a query, we need to search only a small number of nodes to locate matching documents hence making the architecture scalable. We also take into account the fact that nodes in a P2P environment need not have the same capability. We implemented a simulator and performed experiments to study to the performance of our proposed architecture. The results show that our proposed architecture is scalable and highly efficient when handling range queries.
