Automatic service composition is an important issue in the field of grid, which enables individual services to be composed together to provide the end user a more powerful service, which would significantly improve the service reuse. This paper proposes a novel service composition approach based on QoS global optimization which tackles the QoS-aware composition optimization problem using ACO algorithm. The experimental results show that our model is effective and our approach to search the solution outperforms GA.
