Abstract Query optimization in data integration systems over large scale network, faces the challenges of dealing with autonomous, heterogeneous and distributed data sources, dynamic execution environment and changing user requirements. In this paper we introduce system architecture for query optimization. The latter consists of several important phases. We introduce also a cost model to calculate the cost of query execution. In order to optimize the cost of query processing considering the constraints in grid environment, an execution model based on mobile agents for efficient execution of binary relational operators (join) of the query is determined based on the cost model. Finally the paper tests our approach through experiment.
