Fuzzy Neighborhood Allocation (FNA): A fuzzy approach to improve near neighborhood allocation in DDB

Abstract

Allocating data fragments in distributed database systems is an important issue in distributed database (DDB) systems. In this paper, we are going to improve the effectiveness of current NNA algorithm using a Fuzzy inference engine. Results indicate that, our fuzzy based NNA algorithm leads 5% gain in some of systems performance metrics. This algorithm, providing a data clustering mechanism, which is very suitable for DDBS in the networks, with heavy traffic loads, and frequent data access requests. © 2008 Springer-Verlag.
