Abstract :
It is important to reduce access latency and network traffic in distributed database management problem (DDMP). This problem has been formulated as a multiobjective combinatorial optimization problem in the paper. A new approach is proposed that is an intelligent configuration with multiple objectives based on genetic algorithm. Multiple criteria are developed with a goal to provide trade-off optimal performance for Web services. A set of good configurations with diverse spread of DDMP is generated to approximate Pareto front of the optimization problem. The corresponding results demonstrate that the proposed approach is capable of discovering a set of nondominated configurations within a finite genetic generation. Its feasibility and performance has been verified.
