Semantic-Based Grid Resource Discovery Systems

Resource Discovery (RD) is an important key issue in
grid systems since resource reservation and task scheduling are
based on it. Classical grid RD systems use keyword-based
approaches to describe, and discover resources and services.
However, keyword-based approaches are associated with some
deficiencies that are inherited from the appearance of Intergrid
system with various types of resources, services and middleware
in the recent years. Therefore, semantic technology has been
introduced to grid RD system to overcome this matter. A
considerable amount of studies have been done in this context.
Such systems are known as semantic-based RD systems.
Nevertheless, review or survey studies that can compare and
evaluate these studies, and draw the future research directions in
this field remain a challenge. This paper addresses this issue. It
initially discusses the RD system components, semantic
technology and its use in grid systems. The paper then focuses on
the use of semantic technology in grid RD system components
and presents the current work in this perspective. It also presents
a detailed analysis on these systems and the future research
directions of this field. Finally, the paper discusses future
applications of the semantic-based RD system on emerging
technologies such as Meta-brokers and Clouds.
