Since ten years, the Grid systems are hot research topics. Recently, the Grid systems open towards the management of heterogeneous and distributed data on a large-scale environment. The Grid data management raises new problems and presents real challenges:
(i) resource discovery and allocation,
(ii) query optimization,
(iii) monitoring services,
(iv) replication and caching,
(v) cost models,
(vi) autonomic data management, and
The main characteristics offered by these systems are: large scale and dynamics of nodes (unstable system). The synergy and convergence of interests between Grid systems and agent systems have been clearly pointed out. To address some of the above problems, a complementary approach (with respect to P2P techniques) based on mobile agents deserves to be explored and experimented.
In this talk, we draw up a synthetic state of the art of using mobile agents to solve some fundamental problems of data management in grid systems, particularly distributed query processing and optimization. We point out the advantages of mobile agents and how they can help for decentralized control, and scaling.
Abdelkader Hameurlain is full professor in Computer Science at Paul Sabatier University, Toulouse, France. He is a member of the Institute of Research in Computer Science of Toulouse (IRIT). His current research interests are in query optimization in parallel and large scale distributed environments, mobile databases, and database performance. Prof. Hameurlain has been the general chair of the International Conference on Database and Expert Systems Applications (DEXA'02). He was guest editor of two special issues of "International Journal of Computer Systems Science and Engineering on "Mobile Databases" and "Data Management in Grid and P2P Systems".
